The find_next_bit, find_first_bit, find_next_zero_bit
and find_first_zero_bit functions were not properly
clamping to the maxbit argument at the bit level. They
were instead only checking maxbit at the byte level.
To fix this, add a compare and a conditional move
instruction to the end of the common bit-within-the-
byte code used by all the functions and be sure not to
clobber the maxbit argument before it is used.

init_mm used at kernel/sched.c:idle_task_exit() has spin_lock
(init_mm.context.id_lock) that is not initialized when spin_lock/unlock
is called at an ARM machine. Note that mm_struct.context.id_lock is
usually initialized except for the instance of init_mm at
linux/arch/arm/mm/context.c
Not initializing this spinlock incurs "BUG: pinlock bad magic"
warning when spinlock debug is enabled. We have observed such
instances when testing PM in S5PC210 machines.

The .stack section doesn't contain any contents, and doesn't require
initialization either. Rather than marking the output section with
'NOLOAD' but still having it exist in the object files, mark it with
%nobits which avoids the assembler marking the section with 'CONTENTS'.

Commit 8b592783 added a Thumb-2 variant of usracc which, when it is
called with \rept=2, calls usraccoff once with an offset of 0 and
secondly with a hard-coded offset of 4 in order to avoid incrementing
the pointer again. If \inc != 4 then we will store the data to the wrong
offset from \ptr. Luckily, the only caller that passes \rept=2 to this
function is __clear_user so we haven't been actively corrupting user data.
This patch fixes usracc to pass \inc instead of #4 to usraccoff
when it is called a second time.

The current implementation of sched_clock() for the Nomadik
family is based on the clock source that will wrap around without
any compensation. Currently on the Ux500 after 1030 seconds.
Utilize cnt32_to_63 to expand the sched_clock() counter to 63
bits and introduce a keepwarm() timer to assure that sched clock
and this cnt32_to_63 is called atleast once every half period.
When I print out the actual wrap-around time, and using
a year (3600*24*365 seconds) as minumum wrap limit I get an
actual wrap-around of:
sched_clock: using 55 bits @ 8333125 Hz wrap in 416 days

Commit 7c63984b86 (ARM: do not define VMALLOC_END relative to PAGE_OFFSET)
changed VMALLOC_END to be an explicit value. Before this, it was
relative to PAGE_OFFSET and therefore converted to unsigned long
as PAGE_OFFSET is an unsigned long. This introduced the following
build warning. Fix this by changing the explicit defines of
VMALLOC_END to be unsigned long.

Allow the compiler to better optimize the page table walking code
by avoiding over-complex pmd_addr_end() calculations. These
calculations prevent the compiler spotting that we'll never iterate
over the PMD table, causing it to create double nested loops where
a single loop will do.

In:
powerpc/mm: Fix pgtable cache cleanup with CONFIG_PPC_SUBPAGE_PROT
commit d28513bc7f675d28b479db666d572e078ecf182d
Author: David Gibson <david@gibson.dropbear.id.au>
subpage_protection() was changed to to take an mm rather a pgdir but it
didn't change calling site in hashpage_preload(). The change wasn't
noticed at compile time since hashpage_preload() used a void* as the
parameter to subpage_protection().
This is obviously wrong and can trigger the following crash when
CONFIG_SLAB, CONFIG_DEBUG_SLAB, CONFIG_PPC_64K_PAGES
CONFIG_PPC_SUBPAGE_PROT are enabled.

EEH and pci_dlpar #undef DEBUG, but I think they were added before the
ability to control this from Kconfig. It's really annoying to only get
some of the debug messages from these files. Leave the lpar.c #undef
alone as it produces so much output as to make the kernel unusable.

We now use load_gs_index() to load gs safely; unfortunately this also
changes MSR_KERNEL_GS_BASE, which we managed separately. This resulted
in confusion and breakage running 32-bit host userspace on a 64-bit kernel.
Fix by
- saving guest MSR_KERNEL_GS_BASE before we we reload the host's gs
- doing the host save/load unconditionally, instead of only when in guest
long mode
Things can be cleaned up further, but this is the minmal fix for now.

The fix from ba773f7c510c0b252145933926c636c439889207
(x86,kgdb: Fix hw breakpoint regression) was not entirely complete.
The kgdb_remove_all_hw_break() function also needs to call the
hw_break_release_slot() or else a breakpoint can get activated again
after the debugger has detached.
The kgdb test suite exposes the behavior in the form of either a hang
or repetitive failure. The kernel config that exposes the problem
contains all of the following:
CONFIG_DEBUG_RODATA=y
CONFIG_KGDB_TESTS=y
CONFIG_KGDB_TESTS_ON_BOOT=y
CONFIG_KGDB_TESTS_BOOT_STRING="V1F100"

Move the mid-layer's ->queuecommand() invocation from being locked
with the host lock to being unlocked to facilitate speeding up the
critical path for drivers who don't need this lock taken anyway.
The patch below presents a simple SCSI host lock push-down as an
equivalent transformation. No locking or other behavior should change
with this patch. All existing bugs and locking orders are preserved.
Additionally, add one parameter to queuecommand,
struct Scsi_Host *
and remove one parameter from queuecommand,
void (*done)(struct scsi_cmnd *)
Scsi_Host* is a convenient pointer that most host drivers need anyway,
and 'done' is redundant to struct scsi_cmnd->scsi_done.
Minimal code disturbance was attempted with this change. Most drivers
needed only two one-line modifications for their host lock push-down.

Both commits 0a3d763f1a68 ("ptrace: cleanup arch_ptrace() on um") and
9b05a69e0534 ("ptrace: change signature of arch_ptrace()") broke the um
build. This patch fixes the issues.
0a3d763f1a68 introduced the undeclared variable "datavp". The patch seems
completely untested. :-(
9b05a69e0534 changed arch_ptrace()'s signature but did not update
um/include/asm/ptrace-generic.h.

Software generated interrupts (SGI) are used for IPIs by the kernel.
While previous revisions of the GIC hardware were specified not to
implement enable bits for SGIs, more recent hardware is now permitted
to implement these bits in a per-CPU banked register.
The priority registers for the PPI and SGIs are also per-CPU banked
registers, so ensure that these are also appropriately initialized.

Some BIOSes provide PCI host bridge windows that overlap, e.g.,
pci_root PNP0A03:00: host bridge window [mem 0xb0000000-0xffffffff]
pci_root PNP0A03:00: host bridge window [mem 0xafffffff-0xdfffffff]
pci_root PNP0A03:00: host bridge window [mem 0xf0000000-0xffffffff]
If we simply insert these as children of iomem_resource, the second window
fails because it conflicts with the first, and the third is inserted as a
child of the first, i.e.,
b0000000-ffffffff PCI Bus 0000:00
f0000000-ffffffff PCI Bus 0000:00
When we claim PCI device resources, this can cause collisions like this
if we put them in the first window:
pci 0000:00:01.0: address space collision: [mem 0xff300000-0xff4fffff] conflicts with PCI Bus 0000:00 [mem 0xf0000000-0xffffffff]
Host bridge windows are top-level resources by definition, so it doesn't
make sense to make the third window a child of the first. This patch
coalesces any host bridge windows that overlap. For the example above,
the result is this single window:
pci_root PNP0A03:00: host bridge window [mem 0xafffffff-0xffffffff]
This fixes a 2.6.34 regression.

This is a big revert of a lot of -rc1 tidspbridge patches in order to
get the driver back into a working state. It also includes a OMAP patch
that was approved by the OMAP maintainer.
