Pull ARM fixes from Russell King:
"A number of fixes:
Patrik found a problem with preempt counting in the VFP assembly
functions which can cause the preempt count to be upset.
Nicolas fixed a problem with the parsing of the DT when it straddles a
1MB boundary.
Subhash Jadavani reported a problem with sparsemem and our highmem
support for cache maintanence for DMA areas, and TI found a bug in
their strongly ordered memory mapping type.
Also, three fixes by way of Will Deacon's tree from Dave Martin for
instruction compatibility and Marc Zyngier to fix hypervisor boot mode
issues."
* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:

ARM: virt: boot secondary CPUs through the right entry point
ARM: virt: Avoid bx instruction for compatibility with <=ARMv4
Here's a long-pending fixes pull request for arm-soc (I didn't send one
in the -rc4 cycle).
The larger deltas are from:
- A fixup of error paths in the mvsdio driver
- Header file move for a driver that hadn't been properly converted to
multiplatform on i.MX, which was causing build failures when included
- Device tree updates for at91 dealing mostly with their new
pinctrl setup merged in 3.8 and mistakes in those initial configs
The rest are the normal mix of small fixes all over the place; sunxi,
omap, imx, mvebu, etc, etc.

At the moment the MSR driver only relies upon file system
checks. This means that anything as root with any capability set
can write to MSRs. Historically that wasn't very interesting but
on modern processors the MSRs are such that writing to them
provides several ways to execute arbitary code in kernel space.
Sample code and documentation on doing this is circulating and
MSR attacks are used on Windows 64bit rootkits already.
In the Linux case you still need to be able to open the device
file so the impact is fairly limited and reduces the security of
some capability and security model based systems down towards
that of a generic "root owns the box" setup.
Therefore they should require CAP_SYS_RAWIO to prevent an
elevation of capabilities. The impact of this is fairly minimal
on most setups because they don't have heavy use of
capabilities. Those using SELinux, SMACK or AppArmor rules might
want to consider if their rulesets on the MSR driver could be
tighter.

The flush tlb optimization code has logical issue on UV
platform. It doesn't flush the full range at all, since it
simply ignores its 'end' parameter (and hence also the "all"
indicator) in uv_flush_tlb_others() function.
Cliff's notes:
| I tested the patch on a UV. It has the effect of either
| clearing 1 or all TLBs in a cpu. I added some debugging to
| test for the cases when clearing all TLBs is overkill, and in
| practice it happens very seldom.

putreg() assumes that the tracee is not running and pt_regs_access() can
safely play with its stack. However a killed tracee can return from
ptrace_stop() to the low-level asm code and do RESTORE_REST, this means
that debugger can actually read/modify the kernel stack until the tracee
does SAVE_REST again.
set_task_blockstep() can race with SIGKILL too and in some sense this
race is even worse, the very fact the tracee can be woken up breaks the
logic.
As Linus suggested we can clear TASK_WAKEKILL around the arch_ptrace()
call, this ensures that nobody can ever wakeup the tracee while the
debugger looks at it. Not only this fixes the mentioned problems, we
can do some cleanups/simplifications in arch_ptrace() paths.
Probably ptrace_unfreeze_traced() needs more callers, for example it
makes sense to make the tracee killable for oom-killer before
access_process_vm().
While at it, add the comment into may_ptrace_stop() to explain why
ptrace_stop() still can't rely on SIGKILL and signal_pending_state().

The kernel's internal definition of ELF_NGREG uses struct pt_regs, which
means that we disagree with userspace on the size of coredumps since
glibc correctly uses the user-visible struct user_pt_regs.
This patch fixes our ELF_NGREG definition to use struct user_pt_regs
and introduces our own ELF_CORE_COPY_REGS to convert between the user
and kernel structure definitions.

Cong Ding <dinggnu@gmail.com> reports correctly that the variable dummy
is being used without initialization. That said, I can't reproduce this
warning with GCC 4.7.1. However, since the variable dummy servces no
real purpose, I'm going for a different fix. This fix
includes https://patchwork.linux-mips.org/patch/4801/ plus Geert's
suggestion to use ACCESS_ONCE().

When building a 32-bit kernel for RBTX4927 with gcc version 4.1.2 20061115
(prerelease) (Ubuntu 4.1.1-21), I get:
arch/mips/lib/delay.c:24:5: warning: "__SIZEOF_LONG__" is not defined
As a consequence, __delay() always uses the 64-bit "dsubu" instruction.
Replace the check for "__SIZEOF_LONG__ == 4" by "BITS_PER_LONG == 32" to
fix this.

On s390, an architecture-specific implementation of the function
pmdp_set_wrprotect() is missing and the generic version is currently
being used. The generic version does not flush the tlb as it would be
needed on s390 when modifying an active pmd, which can lead to subtle
tlb errors on s390 when using transparent hugepages.
This patch adds an s390-specific implementation of pmdp_set_wrprotect()
including the missing tlb flush.

The function omap_init_ocp2scp() references

This is often because omap_init_ocp2scp lacks a __init

The ia64 function "thread_matches()" has no users since commit
e868a55c2a ("[IA64] remove find_thread_for_addr()"). Remove it.
This allows us to make ptrace_check_attach() static to kernel/ptrace.c,
which is good since we'll need to change the semantics of it and fix up
all the callers.

Patch
5a5a51db78 x86-32: Start out eflags and cr4 clean
... made x86-32 match x86-64 in that we initialize %eflags and %cr4
from scratch. This broke OLPC XO-1.5, because the XO enters the
kernel with paging enabled, which the kernel doesn't expect.
Since we no longer support 386 (the source of most of the variability
in %cr0 configuration), we can simply match further x86-64 and
initialize %cr0 to a fixed value -- the one variable part remaining in
%cr0 is for FPU control, but all that is handled later on in
initialization; in particular, configuring %cr0 as if the FPU is
present until proven otherwise is correct and necessary for the probe
to work.
To deal with the XO case sanely, explicitly disable paging in %cr0
before we muck with %cr3, %cr4 or EFER -- those operations are
inherently unsafe with paging enabled.
NOTE: There is still a lot of 386-related junk in head_32.S which we
can and should get rid of, however, this is intended as a minimal fix
whereas the cleanup can be deferred to the next merge window.
