355e8e8d1b m68knommu: fix invalid flags on coldfire pit clocksource
The m68knommu coldfire pit clocksource looks like it was incorrectly
marked as a continuous clocksource.  Running with it marked as a
continuous clocksource could cause hangs when the system switches to
highres mode or enables nohz.

This patch removes the CLOCK_SOURCE_IS_CONTINUOUS flag on the coldfire pit
clocksource.  This will disallow systems using this clocksource from
entering oneshot mode (disabling highres timers and nohz).

6846ee5ca6 zlib: Fix build of powerpc boot wrapper
Commit ac4c2a3bbe broke the build
of all powerpc boot wrappers.

It attempts to add an include of autoconf.h but used the wrong
path for it. It also adds -D__KERNEL__ to our boot wrapper, both
things that we pretty much didn't do on purpose so far.

We want our boot wrapper to remain independent enough of the kernel
for various reasons, one of them being that you can "wrap" an existing
kernel at distro install time which allows to ship one kernel image
and a set of boot wrappers for different platforms, the wrappers
don't have to be built out of the same kernel build tree.

It's also incorrect to do what the patch does in our boot environment
since we may not have a proper alignment exception handler which means
we may not be able to fixup the few cases where an unaligned access will
need SW emulation (depends on the core variant, could be when crossing
page or segment boundaries for example).

This patch fixes it by putting the old code back in and using the
new "fancy" variant only when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS
is set, which happens not to be set on powerpc since we don't include
autoconf.h. It also reverts the changes to our boot wrapper Makefile.

This means that x86 should, afaik, keep the optimisations since its
boot wrapper does include autoconf.h and define __KERNEL__ (though I
doubt they make that much different outside of slow embedded processors).

6f50248ef0 [S390] duplicate SIGTRAP on signal delivery.

tracehook_signal_handler after the signal frame has been set up.

07105202bd Makefile: do not override LC_CTYPE
Setting LC_CTYPE=C breaks localized messages in some setups. With only
LC_COLLATE=C and LC_NUMERIC=C, we get almost all we need, except for not
so defined character classes and tolower()/toupper(). The former is not
a big issue, because we can assume that e.g. [:alpha:] will always
include a-zA-Z and we only ever process ASCII input. The latter seems
only affect arch/sh/tools/gen-mach-types, which we can handle separately.

So after this patch the meaning of ranges like [a-z], the behavior of
sort and join, etc. should be the same everywhere and at the same time
gcc should be able to print localized waring and error messages.
LC_NUMERIC=C might not be necessary, but setting it doesn't hurt.

e68266b700 x86: xen: 64-bit kernel RPL should be 0
Under Xen 64 bit guests actually run their kernel in ring 3,
however the hypervisor takes care of squashing descriptor the
RPLs transparently (in order to allow them to continue to
differentiate between user and kernel space CS using the RPL).
Therefore the Xen paravirt backend should use RPL==0 instead of
1 (or 3). Using RPL==1 causes generic arch code to take
incorrect code paths because it uses "testl $3, <CS>, je foo"
type tests for a userspace CS and this considers 1==userspace.

This issue was previously masked because get_kernel_rpl() was
omitted when setting CS in kernel_thread(). This was fixed when
kernel_thread() was unified with 32 bit in
f443ff4201.

42590a7501 x86/agp: Fix agp_amd64_init and agp_amd64_cleanup
This fixes the regression introduced by the commit
f405d2c023.

The above commit fixes the following issue:

  http://marc.info/?l=linux-kernel&m=126192729110083&w=2

However, it doesn't work properly when you remove and insert the
agp_amd64 module again.

agp_amd64_init() and agp_amd64_cleanup should be called only
when gart_iommu is not called earlier (that is, the GART IOMMU
is not enabled). We need to use 'gart_iommu_aperture' to see if
GART IOMMU is enabled or not.

c2c5d45d46 perf: Stop stack frame walking off kernel addresses boundaries
While processing kernel perf callchains, an bad entry can be
considered as a valid stack pointer but not as a kernel address.

In this case, we hang in an endless loop. This can happen in an
x86-32 kernel after processing the last entry in a kernel
stacktrace.

Just stop the stack frame walking after we encounter an invalid
kernel address.

This fixes a hard lockup in x86-32.

682137f7e6 m68knommu: fix definitions of __pa() and __va()
Fix compilation breakage of all m68knommu targets:

  CC      arch/m68knommu/kernel/asm-offsets.s
In file included from include/linux/sched.h:77,
                 from arch/m68knommu/kernel/asm-offsets.c:12:
include/linux/percpu.h: In function 'per_cpu_ptr_to_phys':
include/linux/percpu.h:161: error: implicit declaration of function 'virt_to_phy

This is broken in linux-2.6.33-rc3.

Change the definitions of __pa() and __va() to not use virt_to_phys()
and phys_to_virt(). Trivial 1:1 conversion required for the non-MMU case.

A side effect if this is that the m68knommu can now use asm/virtconvert.h
for the definition of virt_to_phys() and phys_to_virt().

Also cleaned up the definition of page_to_phys() when moving into
virtconvert.h.

aff7b4f867 ARM: Ensure ARMv6/7 mm files are built using appropriate assembler options
A kernel with both ARMv6 and ARMv7 selected results in build errors.
Fix this by specifying the proper architectures for these assembly

7511bce406 ARM: Fix wrong dmb
The __kuser_cmpxchg code uses an ARMv6 dmb instruction, rather than
one based upon the architecture being built for.  Switch to using
the macro provided for this purpose, which also eliminates the
need for an ifdef.

d797396f33 MIPS: cpumask_of_node() should handle -1 as a node
pcibus_to_node can return -1 if we cannot determine which node a pci bus
is on. If passed -1, cpumask_of_node will negatively index the lookup array
and pull in random data:

# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus
00000000,00000003,00000000,00000000
# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist
64-65

Change cpumask_of_node to check for -1 and return cpu_all_mask in this
case:

# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpus
ffffffff,ffffffff,ffffffff,ffffffff
# cat /sys/devices/pci0000:00/0000:00:01.0/local_cpulist
0-127

With the advent of function graph tracing on MIPS, Octeon needs a high
precision sched_clock() implementation.  Without it, most timing
numbers are reported as 0.000.

This new sched_clock just uses the 64-bit cycle counter appropriately
scaled.

Since commit 898d357b5262f9e26bc2418e01f8676e80d9867e (lmo) /
6acc7d485c (kernel.org) ("Fix and enhance
built-in kernel command line") arcs_cmdline[] does not contain built-in
command line.  The commit introduce CONFIG_CMDLINE_BOOL and
CONFIG_CMDLINE_OVERRIDE to control built-in command line, and now we can
use them instead of platform-specific built-in command line processing.
