Fixed trivial IPv4/6 address printing conflicts in fs/cifs/connect.c due
to the conversion to %pI (in this networking merge) and the addition of
doing IPv6 addresses (from the earlier merge of CIFS).
Fix kernel-doc notation to use correct syntax. Even though this should be
moved to where the function is actually implemented...

If it is reasonable to apply PTR_ERR to the result of calling clk_get, then
that result should first be tested with IS_ERR, not with !.

[ARM] Fix alignment fault handling for ARMv6 and later CPUs
[ARM] 5340/1: fix stack placement after noexecstack changes
[ARM] 5339/1: fix __fls() on ARM
[ARM] Orion: fix bug in pcie configuration cycle function field mask
[ARM] omap: fix a pile of issues
On ARMv6 and later CPUs, it is possible for userspace processes to
get stuck on a misaligned load or store due to the "ignore fault"
setting; unlike previous CPUs, retrying the instruction without
the 'A' bit set does not always cause the load to succeed.
We have no real option but to default to fixing up alignment faults
on these CPUs, and having the CPU fix up those misaligned accesses
which it can.

Commit 8ec53663d2 ("[ARM] Improve
non-executable support") added support for detecting non-executable
stack binaries. One of the things it does is to make READ_IMPLIES_EXEC
be set in ->personality if we are running on a CPU that doesn't support
the XN ("Execute Never") page table bit or if we are running a binary
that needs an executable stack.
This exposed a latent bug in ARM's asm/processor.h due to which we'll
end up placing the stack at a very low address, where it will bump into
the heap on any application that uses significant amount of stack or
heap or both, causing many interesting crashes.
Fix this by testing the ADDR_LIMIT_32BIT bit in ->personality instead
of testing for equality against PER_LINUX_32BIT.

Commit 0c65f459ce intended to fix truncation issues with fls() on
ARMv5+ by renaming it to __fls() and wrapping it into a C function.
However that didn't take into account the fact that __fls() already
already had different semantics in the kernel.
Let's move the __fls() code into fls() function directly, and redefine
__fls() with the appropriate semantics. While at it, bring a generic
__fls() definition for pre ARMv5 too.

The G3IPL expects the value at RAM address 0xa020b020 to be

Mikael Pettersson reported:
The 2.6.28-rc kernels fail to detect PCI device 0000:00:01.0
(the first ethernet port) on my Thecus n2100 XScale box.
There is however still a strange "ghost" device that gets partially
detected in 2.6.28-rc2 vanilla.
The IOP321 manual says:
The user designates the memory region containing the OCCDR as
non-cacheable and non-bufferable from the IntelR XScaleTM core.
This guarantees that all load/stores to the OCCDR are only of
DWORD quantities.
Ensure that the OCCDR is so mapped.

Same fix as commit c7cf72dcadb: when 'start' and 'end' are less than a

When 'start' and 'end' are less than a cacheline apart and 'start' is
unaligned we are done after cleaning and invalidating the first
cacheline. So check for (start < end) which will not walk off into
invalid address ranges when (start > end).
This issue was caught by drivers/dma/dmatest.
2.6.27 is susceptible.

As a result of the ptebits changes, we ended up marking device mappings
as normal memory on ARMv7 CPUs, resulting in undesirable behaviour with
serial ports and the like. While reviewing the section mapping table
entries, other errors in the memory type settings for devices were
detected and confirmed to prevent Xscale3 platforms booting.

OMAP34xx (ARMv7),
OMAP24xx (ARMv6),
OMAP16xx (ARM926T, ARMv5),

As of 73bdf0a60e, the kernel needs
to know where modules are located in the virtual address space.
On ARM, we located this region between MODULE_START and MODULE_END.
Unfortunately, everyone else calls it MODULES_VADDR and MODULES_END.
Update ARM to use the same naming, so is_vmalloc_or_module_addr()
can work properly. Also update the comment on mm/vmalloc.c to
reflect that ARM also places modules in a separate region from the
vmalloc space.
