* 'for-linus' of git://android.git.kernel.org/kernel/tegra: ARM: Tegra: Harmony: Fix conflicting GPIO numbering
2011-06-05ARM: Tegra: Harmony: Fix conflicting GPIO numberingStephen Warren2-2/+5
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 6f168f2fa60f87e85e0df25e87e2372f22f5eb7c.

2011-05-31sh: Fix up asm-generic/ptrace.h fallout.Paul Mundt1-2/+4
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.

2011-05-29[S390] mm: fix mmu_gather reworkHeiko Carstens1-7/+16
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. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
2011-05-29[S390] mm: fix storage key handlingHeiko Carstens1-8/+8
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.

2011-05-29x86 idle: deprecate mwait_idle() and "idle=mwait" cmdline paramLen Brown1-0/+1
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. cc: x86@kernel.org cc: stable@kernel.org # .39.x Signed-off-by: Len Brown <len.brown@intel.com>
2011-05-29x86 idle: deprecate "no-hlt" cmdline paramLen Brown1-0/+1
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(). cc: x86@kernel.org # .39.x Signed-off-by: Len Brown <len.brown@intel.com>
2011-05-29x86 idle APM: deprecate CONFIG_APM_CPU_IDLELen Brown1-0/+2
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. cc: x86@kernel.org cc: Jiri Kosina <jkosina@suse.cz> cc: stable@kernel.org # .39.x Signed-off-by: Len Brown <len.brown@intel.com>

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.

* 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
2011-05-28ns: Wire up the setns system callEric W. Biederman49-28/+84
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. >  arch/blackfin/include/asm/unistd.h     |    3 ++- >  arch/blackfin/mach-common/entry.S      |    1 + Acked-by: Mike Frysinger <vapier@gentoo.org> Oh - ia64 wiring looks good.

2011-05-28x86: Put back -pg to tsc.o and add no GCOV to vread_tsc_64.oSteven Rostedt1-0/+2
The commit 44259b1abfaa8bb819d25d41d71e8e33e25dd36a 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.

2011-05-28ARM: 6945/1: Add unwinding support for division functionsLaura Abbott1-5/+20
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.
