89c4705ed5 OMAP2+: Fix 9 section mismatch(es) warnings from mach-omap2/built-in.o
The serial*_data should have been marked as __initdata as per
it's usage in the board files. Fix the same to remove the
section mismatch warnings caused by it.

f9fa1bb9d7 ARM: OMAP2: Add missing include of linux/gpio.h
I got some build error like below while executing "make omap2plus_defconfig".

  CC      arch/arm/mach-omap2/board-2430sdp.o
arch/arm/mach-omap2/board-2430sdp.c: In function 'omap_2430sdp_init':

This patch fixes the build error by include linux/gpio.h instead of mach/gpio.h.

571503e100 Merge branch 'setns'
* setns:
  ns: Wire up the setns system call

Done as a merge to make it easier to fix up conflicts in arm due to
addition of sendmmsg system call
2011-05-28 10:51:01 -07:00
Eric W. Biederman
7b21fddd08 ns: Wire up the setns system call
32bit and 64bit on x86 are tested and working.  The rest I have looked
at closely and I can't find any problems.

setns is an easy system call to wire up.  It just takes two ints so I
don't expect any weird architecture porting problems.

While doing this I have noticed that we have some architectures that are
very slow to get new system calls.  cris seems to be the slowest where
the last system calls wired up were preadv and pwritev.  avr32 is weird
in that recvmmsg was wired up but never declared in unistd.h.  frv is
behind with perf_event_open being the last syscall wired up.  On h8300
the last system call wired up was epoll_wait.  On m32r the last system
call wired up was fallocate.  mn10300 has recvmmsg as the last system
call wired up.  The rest seem to at least have syncfs wired up which was
new in the 2.6.39.

v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com>
v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com>
v4: Moved wiring up of the system call to another patch
v5: ported to v2.6.39-rc6
v6: rebased onto parisc-next and net-next to avoid syscall  conflicts.
v7: ported to Linus's latest post 2.6.39 tree.

a2812e1783 arch: add #define for each of optimized find bitops
The style that we normally use in asm-generic is to test the macro itself
for existence, so in asm-generic, do:

	#ifndef find_next_zero_bit_le
	extern unsigned long find_next_zero_bit_le(const void *addr,
		unsigned long size, unsigned long offset);
	#endif

and in the architectures, write

	static inline unsigned long find_next_zero_bit_le(const void *addr,
		unsigned long size, unsigned long offset)
	#define find_next_zero_bit_le find_next_zero_bit_le

This adds the #define for each of the optimized find bitops in the
architectures.

52af9c6cd8 ARM: 6943/1: mm: use TTBR1 instead of reserved context ID
On ARMv7 CPUs that cache first level page table entries (like the
Cortex-A15), using a reserved ASID while changing the TTBR or flushing
the TLB is unsafe.

This is because the CPU may cache the first level entry as the result of
a speculative memory access while the reserved ASID is assigned. After
the process owning the page tables dies, the memory will be reallocated
and may be written with junk values which can be interpreted as global,
valid PTEs by the processor. This will result in the TLB being populated
with bogus global entries.

This patch avoids the use of a reserved context ID in the v7 switch_mm
and ASID rollover code by temporarily using the swapper_pg_dir pointed
at by TTBR1, which contains only global entries that are not tagged
with ASIDs.

a248b13b21 ARM: 6941/1: cache: ensure MVA is cacheline aligned in flush_kern_dcache_area
The v6 and v7 implementations of flush_kern_dcache_area do not align
the passed MVA to the size of a cacheline in the data cache. If a
misaligned address is used, only a subset of the requested area will
be flushed. This has been observed to cause failures in SMP boot where
the secondary_data initialised by the primary CPU is not cacheline
aligned, causing the secondary CPUs to read incorrect values for their
pgd and stack pointers.

This patch ensures that the base address is cacheline aligned before
flushing the d-cache.

The DB8500v2 and DB5500 has a fifth version of the "PL023" and

revision in the PrimeCell peripheral ID registers. Since the

2846d84ffa ARM: 6940/1: fiq: Briefly document driver responsibilities for suspend/resume
Drivers which make use of the FIQ interrupt may require the state
of the FIQ mode registers to be preserved across suspend/resume.

Because the FIQ mode registers are not saved and restored
automatically by the kernel, driver authors will need to do the
appropriate save/restore in their own driver suspend/resume
handlers.

Implementing global automatic save/restore of the FIQ state does
not appear appropriate, since this by itself is not sufficient for
FIQ-based drivers to function correctly across suspend/resume in
any case.

This patch adds a brief explanatory note to fiq.h documenting the
requirement placed on driver authors.

* To remove the risk of inconvenient register allocation decisions

 * The apcs frame manipulation code is not applicable for Thumb-2

   have a full frame on these leaf assembler functions, the frame
   manipulation is removed, in the interests of simplicity.

 * Split up ldm/stm instructions to be compatible with Thumb-2,

40f7bfe4f1 ARM: 6914/1: sparsemem: fix highmem detection when using SPARSEMEM
sanity_check_meminfo walks over the registered memory banks and attempts
to split banks across lowmem and highmem when they would otherwise
overlap with the vmalloc space.

When SPARSEMEM is used, there are two potential problems that occur
when the virtual address of the start of a bank is equal to vmalloc_min.

 1.) The end of lowmem is calculated as __pa(vmalloc_min - 1) + 1.
     In the above scenario, this will give the end address of the
     previous bank, rather than the actual bank we are interested in.
     This value is later used as the memblock limit and artificially
     restricts the total amount of available memory.

 2.) The checks to determine whether or not a bank belongs to highmem
     or not only check if __va(bank->start) is greater or less than
     vmalloc_min. In the case that it is equal, the bank is incorrectly
     treated as lowmem, which hoses the vmalloc area.

This patch fixes these two problems by checking whether the virtual
start address of a bank is >= vmalloc_min and then calculating
lowmem_end by finding the virtual end address of the highest lowmem
bank.

7b7bf499f7 ARM: 6913/1: sparsemem: allow pfn_valid to be overridden when using SPARSEMEM
In commit eb33575c ("[ARM] Double check memmap is actually valid with a
memmap has unexpected holes V2"), a new function, memmap_valid_within,
was introduced to mmzone.h so that holes in the memmap which pass
pfn_valid in SPARSEMEM configurations can be detected and avoided.

The fix to this problem checks that the pfn <-> page linkages are
correct by calculating the page for the pfn and then checking that
page_to_pfn on that page returns the original pfn. Unfortunately, in
SPARSEMEM configurations, this results in reading from the page flags to
determine the correct section. Since the memmap here has been freed,
junk is read from memory and the check is no longer robust.

In the best case, reading from /proc/pagetypeinfo will give you the
wrong answer. In the worst case, you get SEGVs, Kernel OOPses and hung
CPUs. Furthermore, ioremap implementations that use pfn_valid to
disallow the remapping of normal memory will break.

This patch allows architectures to provide their own pfn_valid function
instead of using the default implementation used by sparsemem. The
architecture-specific version is aware of the memmap state and will
return false when passed a pfn for a freed page within a valid section.

5ca43f6c3b lib: consolidate DEBUG_STACK_USAGE option
Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way.  Move it
to lib/Kconfig.debug so each arch doesn't have to define it.  This
obviously makes the option generic, but that's fine because the config is
already used in generic code.

It's not obvious to me that sysrq-P actually does anything caution by
keeping the most inclusive wording.

7bf02ea22c arch, mm: filter disallowed nodes from arch specific show_mem functions
Architectures that implement their own show_mem() function did not pass
the filter argument to show_free_areas() to appropriately avoid emitting
the state of nodes that are disallowed in the current context.  This patch
now passes the filter argument to show_free_areas() so those nodes are now
avoided.

This patch also removes the show_free_areas() wrapper around
__show_free_areas() and converts existing callers to pass an empty filter.

ia64 emits additional information for each node, so skip_free_areas_zone()
must be made global to filter disallowed nodes and it is converted to use
a nid argument rather than a zone for this use case.

so will pass it via system_rev

66ee3bef3c ARM: mach-shmobile: mackerel: add renesas_usbhs support for USB1
renesas_usbhs driver can use external interrupt mode
(which come from USB-PHY) or autonomy mode (it use own interrupt)
for detecting connection/disconnection when Function.
And it will be power OFF while it has been disconnecting
if external interrupt mode is selected.

mackerel board has 2 USB ports.

But we can not use external interrupt mode
on CN22 USB0 port which is only for USB Function.
IRQ7-PORT40 is already used by Touchscreen,
and USB-PHY needs IRQ7-PORT167.
It is impossible to use IRQ7 demux on mackerel.

We can use external interrupt mode USB-Function on "USB1".
USB1 can become Host by r8a66597, and become Function by renesas_usbhs.
But don't select both drivers in same time.
These 2 drivers are not supporting IRQ SHARD.

This is a snapshot of the current PRCMU firmware API as it looks
right now. The PRCMU firmware is still subject to change. This
also updates the CPUfreq driver to a newer version that will
utilize the new API.

mv mach-ux500/include/mach/prcmu-defs.h include/linux/mfd/db8500-prcmu.h

mach-ux500/include/mach/prcmu.h >> include/linux/mfd/db8500-prcmu.h
rm arch/arm/mach-ux500/include/mach/prcmu.h

Then we update different #include statements and Makefile orders etc
to make the PRCMU driver compile, link and boot in the new place
without really changing any code.

Fix the case of too late twd_base initialization for SMP
on sh73a0 which bas been broken because sh73a0 specific
smp_prepare_cpu() and percpu_timer_setup() changed order

6776fba7e2 ARM: mach-shmobile: Disable sh7372 RT side MSTP bits
Update the sh7372 clock code to set the RT side
set of MSTP bits to a fixed disabled state.

The sh7372 SoC contains two sets of MSTP bits,
one for the ARM (SYS) side, and one for the
SH4AL-DSP (RT) side. The actual clock associated
with the MSTP bit will only be stopped when both
sides have set the MSTP bit to disabled mode.

Some MSTP bits are enabled by default after
hardware reset, so this patch adjusts the code
to disable all MSTP bits associated with the RT
side to allow the SYS side to have full control.
