d30cecbcbe MIPS: Don't write ones to reserved entryhi bits.
We've silently been relying on the hardware chopping off excess, reserved
ASID bits for no better reason that it saving an instruction.  Because we
already have:

#define cpu_asid(cpu, mm)       (cpu_context((cpu), (mm)) & ASID_MASK)

in <asm/mmu_context.h>.

We can use a cleanup to avoid writing non-zero bits into the reserved
entryhi bits.  This avoid triggering some debugging assertion in the
Cavium simulator.

89a8640279 NOMMU: Don't pass NULL pointers to fput() in do_mmap_pgoff()
Don't pass NULL pointers to fput() in the error handling paths of the NOMMU
do_mmap_pgoff() as it can't handle it.

The following can be used as a test program:

	int main() { static long long a[1024 * 1024 * 20] = { 0 }; return a;}

Without the patch, the code oopses in atomic_long_dec_and_test() as called by
fput() after the kernel complains that it can't allocate that big a chunk of
memory.  With the patch, the kernel just complains about the allocation size
and then the program segfaults during execve() as execve() can't complete the
allocation of all the new ELF program segments.

1a6f2a7512 Driver core: allow certain drivers prohibit bind/unbind via sysfs
Platform drivers registered via platform_driver_probe() can be bound
to devices only once, upon registration, because discard their probe()
routines to save memory. Unbinding the driver through sysfs 'unbind'
leaves the device stranded and confuses users so let's not create
bind and unbind attributes for such drivers.

39acbc12af Driver core: fix driver_register() return value
In this patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=16dc42e018c2868211b4928f20a957c0c216126c
the check was added for another driver to already claim the same device
on the same bus. But the returned error code was wrong: to modprobe, the
-EEXIST means that _this_ driver is already installed. It therefore
doesn't produce the needed error message when _another_ driver is trying
to register for the same device.  Returning -EBUSY fixes the problem.

b64dc0a597 USB: serial: sierra driver autopm fixes
This patch presents fixes for the autosuspend feature implementation in
sierra usb serial driver in  functions sierra_open(), sierra_close() and
stop_read_write_urbs().

The patch "sierra_close() must resume the device before it notifies it
of a closure" submitted by Oliver Neukum on Wed, October 14 has been
merged as fix in sierra_close() function.

The bug fix  in sierra_open() function restores the autopm interface
state on error condition.

The bug fix in in stop_read_write_urbs() function assures that both
receive and interrupt urbs are recycled.

they are uneeded with the stack builtin and makes rtl81* modules

0b0595bfda Staging: Panel: prevent driver from calling misc_deregister twice on same ressource
This patch prevents the driver from calling misc_deregister twice on the same
ressouce when unloading the driver.
Unloading the driver without this patch results in a Kernel BUG like this:
Panel driver version 0.9.5 registered on parport0 (io=0x378).
BUG: unable to handle kernel paging request at 0000000000100108
IP: [<ffffffff803c02ee>] misc_deregister+0x2d/0x90

Oops: 0002 [] PREEMPT SMP
last sysfs file: /sys/devices/platform/w83627hf.656/in8_input

This patch fixes this issue, although maybe not in the best way possible :)

c7ff91d722 xfs: fix xfs_quota remove error
The xfs_quota returns ENOSYS when remove command is executed.
Reproducable with following steps.

    # mount -t xfs -o uquota /dev/sda7 /mnt/mp1
    # xfs_quota -x -c off -c remove
    XFS_QUOTARM: Function not implemented.

The remove command is allowed during quotaoff, but xfs_fs_set_xstate()
checks whether quota is running, and it leads to ENOSYS.

To solve this problem, add a check for X_QUOTARM.

3b826386d3 xfs: free temporary cursor in xfs_dialloc
Commit bd16956599 seems
to have a slight regression where this code path:

    if (!--searchdistance) {
        /*
         * Not in range - save last search
         * location and allocate a new inode
         */
        ...
        goto newino;
    }

doesn't free the temporary cursor (tcur) that got dup'd in
this function.

This leaks an item in the xfs_btree_cur zone, and it's caught
on module unload:

===========================================================
BUG xfs_btree_cur: Objects remaining on kmem_cache_close()
-----------------------------------------------------------

It seems like maybe a single free at the end of the function might
be cleaner, but for now put a del_cursor right in this code block
similar to the handling in the rest of the function.
