I came across this difference while looking at doing bg locking during bg initialization. This patch: * removes unnecessary casts in the error messages * renames read_inode_bitmap to ext4_read_inode_bitmap * and more substantially, restructures the inode bitmap reading function to be more like the block bitmap counterpart. The change to the inode bitmap reader simplifies the locking to be applied in the next patch.

Currently, the locality group prealloc list is freed only when there is a block allocation failure. This can result in large number of entries in the preallocation list making ext4_mb_use_preallocated() expensive. To fix this, we convert the locality group prealloc list to a hash list. The hash index is the order of number of blocks in the prealloc space with a max order of 9. When adding prealloc space to the list we make sure total entries for each order does not exceed 8. If it is more than 8 we discard few entries and make sure the we have only <= 5 entries.

Here is the scenario: (1) update inode_A at the block_B (2) pdflush writes out new inode_A to the filesystem, but it results in write I/O error, at this point, BH_Uptodate flag of the buffer for block_B is cleared and BH_Write_EIO is set (3) create new inode_C which located at block_B, and __ext4_get_inode_loc() tries to read on-disk block_B because the buffer is not uptodate (4) if it can read on-disk block_B successfully, inode_A is overwritten by old data This patch makes __ext4_get_inode_loc() not read the inode block if the buffer has BH_Write_EIO flag. In this case, the buffer should have the latest information, so setting the uptodate flag to the buffer (this avoids WARN_ON_ONCE() in mark_buffer_dirty().) According to this change, we would need to test BH_Write_EIO flag for the error checking. Currently nobody checks write I/O errors on metadata buffers, but it will be done in other patches I'm working on.

But this behavior is unintended, and we found that it has been adopted accidentally. This patch undoes it and just calls printk() instead of aborting the journal. Unlike a similar patch for ext3/jbd, file data buffers are written via generic_writepages(). But we also need to set AS_EIO into their mappings because wait_on_page_writeback_range() clears AS_EIO before a user process sees it.

Nevertheless it's possible for Linux to be more resolent about this situation (and similar situations) and work around this bug, by cross-checking the mmconf range against the e820 table and ACPI resources. Change the mconf bus range from [0,0xff] to to [0, 0x3f] to match range [0xf0000000, 0xf4000000) in e820 tables.

Most of the written info is the same all the time, but memset(0) is very wrong. If ->sigq is queued we can race with collect_signal() which can fail to find this siginfo looking at .si_signo, or copy_siginfo() can copy the wrong .si_code/si_tid/etc. In short, sys_timer_settime() can in fact stop the active timer, or the user can receive the siginfo with the wrong .si_xxx values. Move "memset(->info, 0)" from posix_timer_event() to alloc_posix_timer(), change send_sigqueue() to set .si_overrun = 0 when ->sigq is not queued. It would be nice to move the whole sigq->info initialization from send to create path, but this is not easy to do without uglifying timer_create() further. As Roland rightly pointed out, we need more cleanups/fixes here, see the "FIXME" comment in the patch. Hopefully this patch makes sense anyway, and it can mask the most bad implications.

What do you think? restore_fpu_checking() calls init_fpu() in error conditions. While this is wrong(as our main intention is to clear the fpu state of the thread), this was benign before commit 92d140e21f1 ("x86: fix taking DNA during 64bit sigreturn"). Post commit 92d140e21f1, live FPU registers may not belong to this process at this error scenario. In the error condition for restore_fpu_checking() (especially during the 64bit signal return), we are doing init_fpu(), which saves the live FPU register state (possibly belonging to some other process context) into the thread struct (through unlazy_fpu() in init_fpu()). This is wrong and can leak the FPU data. For the signal handler restore error condition in restore_i387(), clear the fpu state present in the thread struct(before ultimately sending a SIGSEGV for badframe). For the paranoid error condition check in math_state_restore(), send a SIGSEGV, if we fail to restore the state.

If there is no reserved block at all, we shouldn't need to do so. But current code still tries to release the reserved blocks regardless whether the counters's value is 0. Continue to do that causes the later calculation to go wrong and a kernel BUG_ON() caught that. This doesn't happen for extent-based files, as the calculation for 0 reserved blocks was right for extent based file. This patch fixed the kernel BUG() due to above reason. It adds checks for 0 to avoid unnecessary release and fix calculation for non-extent files.

Some of the flex groups searched have free blocks and free inodes, but the flex_freeb_ratio is < 10, so they're skipped. Then when a group is compared to the current "best" flex group, it does not have more free blocks than "best", so it is skipped as well. This continues until no flex group with free inodes is found which has a proper ratio or which has more free blocks than the "best" group, and we're left with a "best" group that has 0 inodes free, and we return -ENOSPC.

The current calculation of how many index/leaf blocks should be accounted is too conservetive, it always considered the worse case, where the tree level is 5, and in the case of multiple chunk allocations, it always assumed no blocks were dirtied in common across the allocations. This path uses the accurate depth of the inode with some extras to calculate the index blocks, and also less conservative in the case of multiple allocation accounting.

This patch uses the helper function in DIO and fallocate case, passing a flag indicating that the modified data are contigous thus could account less indirect/index blocks. This patch also fixed the journal credit reservation for direct I/O (DIO). Previously the estimated credits for DIO only was calculated for non-extent files, which was not enough if the file is extent-based. Also fixed was fallocate double-counting credits for modifying the the superblock.

This makes sure we don't take too much journal credits during writeout. We also don't limit the pages to write. That means we loop through the dirty pages building largest possible contiguous block request. Then we issue a single get_block request. We may get less block that we requested. If so we would end up not mapping some of the buffer_heads. That means those buffer_heads are still marked delay. Later in the writepage callback via __mpage_writepage we redirty those pages. We should also not limit/throttle wbc->nr_to_write in the filesystem writepages callback.

Since we didn't know exactly how many blocks would need to be allocated, the estimated journal credits required was very conservative and caused many issues. With the reworked delayed allocation, a new transaction is created for each get_block(), thus we don't need to guess how many credits for the multiple chunk of allocation. We start every transaction with enough credits for inserting a single exent. When estimate the credits for indirect blocks to allocate a chunk of blocks, we need to know the number of data blocks to allocate. We use the total number of reserved delalloc datablocks; if that is too big, for non-extent files, we need to limit the number of blocks to EXT4_MAX_TRANS_BLOCKS. Code cleanup from Aneesh.

No idea what happened. This puts back the missing bits. --rmk) The initial patch from Lothar, and Lennert make it into a cleaner one, modified and tested on PXA320 by Eric Miao. This patch moves the L2 cache operations out of proc-xsc3.S into dedicated outer cache support code. CACHE_XSC3L2 can be deselected so no L2 cache specific code will be linked in, and that L2 enable bit will not be set, this applies to the following cases: a. _only_ PXA300/PXA310 support included and no L2 cache wanted b. PXA320 support included, but want L2 be disabled So the enabling of L2 depends on two things: - CACHE_XSC3L2 is selected - and L2 cache is present Where the latter is only a safeguard (previous testing shows it works OK even when this bit is turned on). IXP series of processors with XScale3 cannot disable L2 cache for the moment since they depend on the L2 cache for its coherent memory, so IXP may always select CACHE_XSC3L2. Other L2 relevant bits are always turned on (i.e. the original code enclosed by #if L2_CACHE_ENABLED .. #endif), as they showed no side effects. Specifically, these bits are: - OC bits in TTBASE register (table walk outer cache attributes) - LLR Outer Cache Attributes (OC) in Auxiliary Control Register Signed-off-by: Lothar WaÃ<9f>mann Signed-off-by: Lennert Buytenhek Signed-off-by: Eric Miao Signed-off-by: Russell King --- arch/arm/mm/Kconfig | 8 ++ arch/arm/mm/cache-xsc3l2.c | 182 +++++++++++++++++++++++++++++++++++++ arch/arm/mm/proc-xsc3.S | 22 ----- 3 files changed, 190 insertions(+), 22 deletions(-) create mode 100644 arch/arm/mm/cache-xsc3l2.c diff --git a/arch/arm/mm/Kconfig b/arch/arm/mm/Kconfig index 399d1d66bf93..ed15f876c725 100644 --- a/arch/arm/mm/Kconfig +++ b/arch/arm/mm/Kconfig @@ -742,3 +742,11 @@ config CACHE_L2X0 select OUTER_CACHE help This option enables the L2x0 PrimeCell. + +config CACHE_XSC3L2 + bool "Enable the L2 cache on XScale3" + depends on CPU_XSC3 + default y + select OUTER_CACHE + help + This option enables the L2 cache on XScale3. diff --git a/arch/arm/mm/cache-xsc3l2.c b/arch/arm/mm/cache-xsc3l2.c new file mode 100644 index 000000000000..158bd96763d3 --- /dev/null +++ b/arch/arm/mm/cache-xsc3l2.c @@ -0,0 +1,182 @@ +/* + * arch/arm/mm/cache-xsc3l2.c - XScale3 L2 cache controller support + * + * Copyright (C) 2007 ARM Limited + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It seems cdrwtool in the udftools has been unusable on "modern" kernels for some time. A Google search reveals many people with the same issue but no solution (cdrwtool fails to format the disk). After spending some time tracking down the issue, it comes down to the following: The udftools still use the older CDROM_SEND_PACKET interface to send things like FORMAT_UNIT through to the drive. They should really be updated, but that's another story. Since most distros are using libata now, the cd or dvd burner appears as a SCSI device, and we wind up in block/scsi_ioctl.c. Here, the code tries to take the "struct cdrom_generic_command" and translate it and stuff it into a "struct sg_io_hdr" structure so it can pass it to the modern sg_io() routine instead. Unfortunately, there is one error, or rather an omission in the translation. The timeout that is passed in in the "struct cdrom_generic_command" is in HZ=100 units, and this is modified and correctly converted to jiffies by use of clock_t_to_jiffies(). However, a little further down, this cgc.timeout value in jiffies is simply copied into the sg_io_hdr timeout, which should be in milliseconds. Since most modern x86 kernels seems to be getting build with HZ=250, the timeout that is passed to sg_io and eventually converted to the timeout_per_command member of the scsi_cmnd structure is now four times too small. Since cdrwtool tries to set the timeout to one hour for the FORMAT_UNIT command, and it takes about 20 minutes to format a 4x CDRW, the SCSI error-handler kicks in after the FORMAT_UNIT completes because it took longer than the incorrectly-calculated timeout.

After much debugging with Peter Zijlstra it turned out that the problem is caused by the string of sched_clock() changes - they caused the CPU clock to jump backwards a bit - which confuses the scheduler arithmetics. (which is unsigned for performance reasons) So revert: # c300ba2: sched_clock: and multiplier for TSC to gtod drift # c0c8773: sched_clock: only update deltas with local reads. # af52a90: sched_clock: stop maximum check on NO HZ # f7cce27: sched_clock: widen the max and min time This solves the interactivity problems.

Therefore it is never necessary to traverse through a node more than once to get a correct answer to the given query. Take advantage of this property using a global ID counter so that we need not clear all the markers in all the lock_class entries before doing a traversal. A new ID is choosen when we start to traverse, and we continue through a lock_class only if it's ID hasn't been marked with the new value yet. This short-circuiting is essential especially for high CPU count systems. The scheduler has a runqueue per cpu, and needs to take two runqueue locks at a time, which leads to long chains of backwards and forwards subgraphs from these runqueue lock nodes. Without the short-circuit implemented here, a graph traversal on a runqueue lock can take up to (1 << (N - 1)) checks on a system with N cpus. For anything more than 16 cpus or so, lockdep will eventually bring the machine to a complete standstill. Signed-off-by: David S.

The story is that what we used to do when we actually used smp_report_regs() is that if you specifically only wanted to have the current cpu's registers dumped you would call "__show_regs()" otherwise you would call show_regs() which also invoked smp_report_regs(). Now that we killed off smp_report_regs() there is no longer any reason to have these two routines, just show_regs() is sufficient.

Sorry for being dense :-/ The below changes the annotation from a lock class per cpu, to a single nested lock, as the scheduler never holds more that 2 rq locks at a time anyway. If there was code requiring holding all rq locks this would not work and the original annotation would be the only option, but that not being the case, this is a much lighter one.

This difficulty has not made much sense until it was realized that it was possible for mac80211 to make a call to the config routine while that routine was already being executed. On this device, it is necessary to loopback the TX when changing channels. Unless this is properly restored, the device will lockup. A mutex now protects the device state, and the private data in several places. The problem was found by Herton Ronaldo Krzesinski , who also suggested this type of fix.

This was traced to splice_direct_to_actor() returning a short or zero count when racing with page invalidation. However this is not FUSE or NFSD specific, other filesystems (notably NFS) also call invalidate_inode_pages2() to purge stale data from the cache. If this happens while such pages are sitting in a pipe buffer, then splice(2) from the pipe can return zero, and read(2) from the pipe can return ENODATA. The zero return is especially bad, since it implies end-of-file or disconnected pipe/socket, and is documented as such for splice. But returning an error for read() is also nasty, when in fact there was no error (data becoming stale is not an error). The same problems can be triggered by "hole punching" with madvise(MADV_REMOVE). Fix this by not clearing the PG_uptodate flag on truncation and invalidation.

However, some apps such as libdc1394 relied on the presence of that bug in order to function correctly. In order to stay compatible with old versions of those apps, this patch preserves the bug in cases where it is harmless to normal operation (such as the single quadlet read) due to a simple duplication of data. This guarantees maximum compatability for those users who are using the old app with the fixed kernel.

This is because even though we can't fragment packets within SCTP due to the prtocol's inherent faults, we can still fragment it at IP layer. By setting the DF bit we will improve the PMTU process. RFC 2960 only says that we SHOULD clear the DF bit in this case, so we're compliant even if we set the DF bit. In fact RFC 4960 no longer has this statement. Once we make this change, we only need to control the local fragmentation. There is already a bit in the skb which controls that, local_df. So this patch sets that instead of using the ipfragok argument. The only complication is that there isn't a struct sock object per transport, so for IPv4 we have to resort to changing the pmtudisc field for every packet. This should be safe though as the protocol is single-threaded. Note that after this patch we can remove ipfragok from the rest of the stack too. Signed-off-by: Herbert Xu Signed-off-by: David S.

On the Freescale MPC8610 DMA ASoC driver, this caused the DMA controller to be unneccessarily re-programmed, and apparently it doesn't like that. The DMA will then not operate when instructed.

The rtnl lock is already held in this path. The function fw_supports_fastreg() was introduced in 2.6.27 to conditionally set the IB_DEVICE_MEM_MGT_EXTENSIONS bit iff the firmware was at 7.0 or greater, and this function also acquires the rtnl lock and which thus causes a deadlock. Further, if iw_cxgb3 is loaded _after_ the nic interface is brought up, then the deadlock does not occur and therefore fw_supports_fastreg() does need to grab the rtnl lock in that path. It turns out this code is all useless anyway. The low level driver will NOT allow the open if the firmware isn't 7.0, so iw_cxgb3 can always set the MEM_MGT_EXTENSIONS bit. Simplify...

Subject: [PATCH 0271/1568] [IA64] update generic_defconfig to support sn2. This patch changes the generic_defconfig so it works on all sn2 platforms I have access to. There is only one support configuration which was not tested and that configuration is only a combination of two tested configurations. With this patchset applied, a generic kernel can be booted on either a RHEL 5.2, RHEL5.3, or SLES10 SP1 root and operate. All features needed by SGI's ProPack are also working. I have not tested all features of RHEL or SLES, but they do at least boot.

Not being able to resolve the name member of the led device structure to a meaningful value leads to confusion during ad-hoc debugging and potential breakage in the future, if we ever decide to access the name member outside of the registration function. Move the buffer to our private per led device structures so that it is accessible after registration. A quick grep didn't yield any occurence of using the led device name parameter outside of the led device registration function, so currently we should already be safe for normal operation.

And now the reason has finally become apparent: It breaks TX capabilities As soon as the device has been associated all following TX frames will be queued in the hardware and never transmitted to the air. Disabling sections of the link tuner did not have the expected result, but completely disabling the link tuner did have the right result (Both of my rt2570 devices came back to life).

For these cases the callers make sure: 1) The cpus indicated are online. 2) The current cpu is not in the list of indicated cpus. Therefore we can pass a pointer to the mask directly. One of the motivations in this transformation is to make use of "&cpumask_of_cpu(cpu)" which evaluates to a pointer to constant data in the kernel and thus takes up no stack space. Hopefully someone in the future will change the interface of arch_send_call_function_ipi() such that it passes a const cpumask_t pointer so that this will optimize ever further.

Slowing the SPI clock down to 9 MHz reduced the occurrence of the hang from "always" during boot to a nuisance level that allowed other SW development to continue. Finally had to address this issue when an application stresses the I/O to always cause a hang. Hang seems to be caused by a missed SPI interrupt, so that the task ends up waiting forever after calling spi_sync(). The fix has 2 parts. First is to halt the DMA engine before the "current" PDC registers are loaded. This ensures that the "next" registers are loaded before the DMA operation takes off. The second part of the fix is a kludge that adds a "completion" interrupt in case the ENDRX interrupt for the last segment of the DMA chaining operation was missed. The patch allows the SPI clock for the serial flash to be increased from 9 MHz to 15 MHz (or more?). No hangs or SPI overruns were encountered. Haavard: while this patch does indeed improve things, I still see overruns and CRC errors on my NGW100 board when running the DataFlash at 10 MHz. However, I think some improvement is better than nothing, so I'm passing this on for inclusion in 2.6.27.

When I tested the same on older kernels like 2.6.18, I got the correct result i.e errno 12 (ENOMEM). I think in source code mlock(2), setting errno ENOMEM has been missed in do_mlock() , on mlock_fixup() failure. SUSv3 requires the following behavior frmo mlock(2). [ENOMEM] Some or all of the address range specified by the addr and len arguments does not correspond to valid mapped pages in the address space of the process. [EAGAIN] Some or all of the memory identified by the operation could not be locked when the call was made. This rule isn't so nice and slighly strange. but many people think POSIX/SUS compliance is important.

That turns out to have a deadlock. The actual fix is really major and I've got it lined up as part of the ops changes for 2.6.28 so for 2.6.26/2.6.27 it is safer to reintroduce this ages old minor bug.

Within a single qdisc this could be avoided by other means easily, upper qdiscs would still increase the counter when we return anything besides NET_XMIT_SUCCESS though. This means we need a new NET_XMIT return value to indicate this to the upper qdiscs. So I'd suggest to introduce NET_XMIT_STOLEN, return that to upper qdiscs and translate it to NET_XMIT_SUCCESS in dev_queue_xmit, similar to NET_XMIT_BYPASS." David Miller noticed: "Maybe these NET_XMIT_* values being passed around should be a set of bits. They could be composed of base meanings, combined with specific attributes. So you could say "NET_XMIT_DROP | __NET_XMIT_NO_DROP_COUNT" The attributes get masked out by the top-level ->enqueue() caller, such that the base meanings are the only thing that make their way up into the stack. If it's only about communication within the qdisc tree, let's simply code it that way." This patch is trying to realize these ideas. Signed-off-by: Jarek Poplawski Signed-off-by: David S.

A recent patch allowed do_md_stop to know whether it was being called via an ioctl or not, and thus where to allow for an extra open file descriptor when checking if it is in use. This broke then switch to readonly performed by the shutdown notifier, which needs to work even when the array is still (apparently) active (as md doesn't get told when the filesystem becomes readonly). So restore this feature by pretending that there can be lots of file descriptors open, but we still want do_md_stop to switch to readonly.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The raid10 resync/recovery code currently limits the amount of in-flight resync IO to 2Meg. This was copied from raid1 where it seems quite adequate. However for raid10, some layouts require a bit of seeking to perform a resync, and allowing a larger buffer size means that the seeking can be significantly reduced. There is probably no real need to limit the amount of in-flight IO at all. Any shortage of memory will naturally reduce the amount of buffer space available down to a set minimum, and any concurrent normal IO will quickly cause resync IO to back off. The only problem would be that normal IO has to wait for all resync IO to finish, so a very large amount of resync IO could cause unpleasant latency when normal IO starts up. So: increase RESYNC_DEPTH to allow 32Meg of buffer (if memory is available) which seems to be a good amount. Also reduce the amount of memory reserved as there is no need to keep 2Meg just for resync if memory is tight. Thanks to Keld for the suggestion.

The first hunk of the patch removes an unnecessary tg3_set_power_state() call. The chip will already be in the D0 state either due to a chip reset or through a previous call to tg3_set_power_state(). The second hunk of the patch moves the tg3_set_power_state() call outside the critical section guarded by tg3_full_lock() and tg3_full_unlock() functions. The power state of the device is and should be outside the lock's domain and all other tg3_set_power_state() calls support this.

The bigger the object size, the more pages we keep on the partial list. I tested SLAB, SLUB, and SLUB with this patch on Jens Axboe's 'netio' example script of the fio benchmarking tool. The script stresses the networking subsystem which should also give a fairly good beating of kmalloc() et al. To run the test yourself, first clone the fio repository: git clone git://git.kernel.dk/fio.git and then run the following command n times on your machine: time ./fio examples/netio The results on my 2-way 64-bit x86 machine are as follows: [ the minimum, maximum, and average are captured from 50 individual runs ] real time (seconds) min max avg sd SLAB 22.76 23.38 22.98 0.17 SLUB 22.80 25.78 23.46 0.72 SLUB (dynamic) 22.74 23.54 23.00 0.20 sys time (seconds) min max avg sd SLAB 6.90 8.28 7.70 0.28 SLUB 7.42 16.95 8.89 2.28 SLUB (dynamic) 7.17 8.64 7.73 0.29 user time (seconds) min max avg sd SLAB 36.89 38.11 37.50 0.29 SLUB 30.85 37.99 37.06 1.67 SLUB (dynamic) 36.75 38.07 37.59 0.32 As you can see from the above numbers, this patch brings SLUB to the same level as SLAB for this particular workload fixing a ~2% regression. I'd expect this change to help similar workloads that allocate a lot of objects that are close to the size of a page.

Tue, 5 Aug 2008 13:49:09 +0200 Subject: [PATCH 0370/1568] avr32: Introduce arch/avr32/mach-*/include/mach Add arch/avr32/mach-*/include to include search path and copy all the files from include/asm/arch there. The old files will be removed once ARM does the same change and all common drivers are converted.

This could either turn out to be instantaneous, or horribly slow depending on the load of the machine. As there is nothing preventing us from enabling forwarding straight away, this patch eliminates this potential delay by executing the code directly if the forward delay is zero. The effect of this problem is that immediately after the carrier comes on a port, the bridge will drop all packets received from that port until it enters forwarding mode, thus causing unnecessary packet loss. Note that this patch doesn't fully remove the delay due to the link watcher. We should also check the carrier state when we are about to drop an incoming packet because the port is disabled. But that's for another patch. -------------------- This version of the fix takes a different approach, in that it just does the state change directly. Signed-off-by: David S.

When it does this, it does not take the setgid bit on the parent directory into account. This patch has CIFS flip on the setgid bit when the parent directory has it. If the share is mounted with "setuids" then also change the group owner to the gid of the parent. This patch should apply cleanly on top of the setattr cleanup patches that I sent a few weeks ago.

That regression was not root-caused by the original commit, it was just uncovered by it, and the real fix was done by Alan Stern in commit 580da34847488b404218d1d7f53b156f245f5555 ("Fix USB storage hang on command abort"). We can thus re-introduce the change that was confirmed by Alan Jenkins to be still required by his odd card reader.

Any Interrupt can wake the core form it's idle state. - Remove deep sleep mode as it is not going to be used anywhere: We support sleep, sleep deeper and hibernate.

It adds 3 new functions that are called instead of having the same code spread throughout the driver. It also removes the cciss_getgeometry function. The patch is fairly complex but we haven't figured out how to make it any simpler and still do everything that needs to be done. Some of the complexity comes from having to special case booting from cciss. Otherwise the gendisk doesn't get added in time and the switchroot will fail. Signed-off-by: Stephen M.

We must ping the watchdog from the kernel until the userspace handles it. MPC83xx CPUs are only differ in a way that watchdog could be disabled once, but after it was enabled via software it becomes just the same as MPC86xx. Thus, to support MPC86xx I added the kernel timer which pings the watchdog until the userspace opens it. Since we implemented the timer, now we're able to implement proper handling for the CONFIG_WATCHDOG_NOWAYOUT case, for MPC83xx and MPC86xx. Also move the probe code into subsys_initcall, because we want start pinging the watchdog ASAP, and misc devices are available in subsys_initcall.

Both registers are available on the MPC8xx, and seem to have the same offsets and semantics as in MPC83xx/MPC86xx watchdogs. The only difference is prescale value. So this driver simply works on the MPC8xx CPUs. One quirk is needed for the MPC8xx, though. It has small prescale value and slow CPU, so the watchdog resets board prior to the driver has time to load. To solve this we should split initialization in two steps: start ping the watchdog early, and register the watchdog userspace interface later. MPC823 seem to be the first CPU in MPC8xx line, so we use fsl,mpc823-wdt compatible matching.

This patch takes cares of the indentation as described in chapter 1. Main changes: * Re-structure the ioctl switch call for all drivers as follows: switch (cmd) { case WDIOC_GETSUPPORT: case WDIOC_GETSTATUS: case WDIOC_GETBOOTSTATUS: case WDIOC_GETTEMP: case WDIOC_SETOPTIONS: case WDIOC_KEEPALIVE: case WDIOC_SETTIMEOUT: case WDIOC_GETTIMEOUT: case WDIOC_GETTIMELEFT: default: } This to make the migration from the drivers to the uniform watchdog device driver easier in the future.

That macro could probably be improved to be along the lines of #define snd_assert(expr, args...) do { if ((void)(expr),0) { args; } } while (0) or similar to make sure that we always both evaluate 'expr' and parse 'args', but while gcc should optimize it all away, I'm too lazy to really verify that.

It's ok, but if drivers set IFF_PROMISC flag when they set promisc, it will broken upper layer handle for promisc and allmulti. In addition, drivers can use their own hardware programming to make it. So do not allow drivers to set IFF_* flags. This is a general driver fix, so I didn't split it to pieces and send to specific driver maintainers.

This patch breaks up the monolithic mii monitor into two phases: an inspection phase, followed by an optional commit phase. The commit phase is the only portion that requires RTNL or makes changes to state, and is only called when inspection finds something to change.

When last IPoIB slave is unenslaved from by writing to a sysfs file (for bond0 this would be /sys/class/net/bond0/bonding/slaves) the driver tries to destroy the bond. This is wrong and can lead to a lockup or a crash. This fix lets the bonding master stay and relies on the user to destroy the bonding master if necessary (i.e. before module ib_ipoib is unloaded) This patch affects only bonds of IPoIB slaves. Ethernet slaves stay unaffected.

Remove asm/hardware.h, use asm/arch/hardware.h instead Remove includes of asm/hardware.h in addition to asm/arch/hardware.h. Then, since asm/hardware.h only exists to include asm/arch/hardware.h, update everything to directly include asm/arch/hardware.h and remove asm/hardware.h.
