Stephen Warren f2a4d8ae4d ARM: Tegra: Harmony: Fix conflicting GPIO numbering
Currently, both the WM8903 and TPS6586x chips attempt to register with
gpiolib using the same GPIO numbers. This causes the audio driver to
fail to initialize.

To solve this, add a define to board-harmony.h for the TPS6586x, and make
board-harmony-power.c use this define, instead of directly referencing
TEGRA_NR_GPIOS.

This fixes a regression introduced by commit
6f168f2fa6.

Paul Mundt db7eba292e sh: Fix up asm-generic/ptrace.h fallout.
There was an ordering issue with regards to instruction_pointer() being
used in profile_pc() prior to the asm-generic/ptrace.h include, which
subsequently provided the instruction_pointer() definition. In the
interest of simplicity we simply open-code the regs->pc deref for the
profile_pc() definition instead.

The FP functions were also broken due to a lack of a common regs->fp,
so provide a common GET_FP() that is safe for both architectures in order
to fix up the frame pointer helpers too.

Heiko Carstens 3c5cffb66d [S390] mm: fix mmu_gather rework
Quite a few functions that get called from the tlb gather code require that
preemption must be disabled. So disable preemption inside of the called
functions instead.
The only drawback is that rcu_table_freelist_finish() doesn't get necessarily
called on the cpu(s) that filled the free lists. So we may see a delay, until
we finally see an rcu callback. However over time this shouldn't matter.

So we get rid of lots of "BUG: using smp_processor_id() in preemptible"
messages.

Heiko Carstens a43a9d93d4 [S390] mm: fix storage key handling
page_get_storage_key() and page_set_storage_key() expect a page address
and not its page frame number. This got inconsistent with 2d42552d
"[S390] merge page_test_dirty and page_clear_dirty".

Result is that we read/write storage keys from random pages and do not
have a working dirty bit tracking at all.
E.g. SetPageUpdate() doesn't clear the dirty bit of requested pages, which
for example ext4 doesn't like very much and panics after a while.

Len Brown 5d4c47e019 x86 idle: deprecate mwait_idle() and "idle=mwait" cmdline param
mwait_idle() is a C1-only idle loop intended to be more efficient
than HLT on SMP hardware that supports it.

But mwait_idle() has been replaced by the more general
mwait_idle_with_hints(), which handles both C1 and deeper C-states.
ACPI uses only mwait_idle_with_hints(), and never uses mwait_idle().

Deprecate mwait_idle() and the "idle=mwait" cmdline param
to simplify the x86 idle code.

After this change, kernels configured with
(!CONFIG_ACPI=n && !CONFIG_INTEL_IDLE=n) when run on hardware
that support MWAIT will simply use HLT.  If MWAIT is desired
on those systems, cpuidle and the cpuidle drivers above
can be used.

We'd rather that modern machines not check if HLT works on
every entry into idle, for the benefit of machines that had
marginal electricals 15-years ago.  If those machines are still running
the upstream kernel, they can use "idle=poll".  The only difference
will be that they'll now invoke HLT in machine_hlt().

We don't want to export the pm_idle function pointer to modules.
Currently CONFIG_APM_CPU_IDLE w/ CONFIG_APM_MODULE forces us to.

CONFIG_APM_CPU_IDLE is of dubious value, it runs only on 32-bit
uniprocessor laptops that are over 10 years old.  It calls into
the BIOS during idle, and is known to cause a number of machines
to fail.

Removing CONFIG_APM_CPU_IDLE and will allow us to stop exporting
pm_idle.  Any systems that were calling into the APM BIOS
at run-time will simply use HLT instead.

this workaround is specific to AMD's version of C1E.
Use the string "e400" to clarify that the workaround is specific

Mike Frysinger d09fb60203 Blackfin: debug-mmrs: fix typos with gptimers/mdma/ppi
This code was mostly developed against a BF54x, so some BF537-specific

The PPI block starts at PPI_CONTROL, not PPI_STATUS (which is the reverse
of the EPPI block).

The MDMA block starts at MDMA_NEXT_DESC_PTR, not MDMA_CONFIG.  Seems the
sim does not catch misreads here so that'll need to get fixed.

The gptimer block is mostly 32bit regs, not 16bit.  Use the gptimer struct

Linus Torvalds 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.

Steven Rostedt 89e1be50c6 x86: Put back -pg to tsc.o and add no GCOV to vread_tsc_64.o
The commit 44259b1abf
    Author: Andy Lutomirski <luto@MIT.EDU>
    x86-64: Move vread_tsc into a new file with sensible options

Removed the -pg from tsc.o which caused the function graph tracer
to go into an infinite function call recursion as it uses the tsc
internally outside its recursion protection, thus tracing the tsc
breaks the function graph tracer.

This commit also added the file vread_tsc_64.c that gets used
by vdso but failed to prevent GCOV from monkeying with it,
causing userspace to try to access kernel data when GCOV was
enabled.

Thanks to Thomas Gleixner for pointing out GCOV as the likely
culprit that added strange kernel accesses into the vread_tsc()
call.

Laura Abbott 81479c246c ARM: 6945/1: Add unwinding support for division functions
The software division functions never had unwinding annotations
added. Currently, when a division by zero occurs the backtrace shown
will stop at Ldiv0 or some completely unrelated function. Add
unwinding annotations in hopes of getting a more useful backtrace
when a division by zero occurs.
