2013-09-29Revert "perf symbols: Demangle cloned functions"Ingo Molnar
This reverts commit de95ab53645a2f0015e0f68ee723f18dce2b8b51. Markus Trippelsdorf reported that this commit broke 'perf top': > I just see a gray screen with no text at all. Sometimes the > following error messages are printed: > > *** Error in `perf': invalid fastbin entry (free): 0x00000000029b18c0 > *** > *** Error in `perf': malloc(): memory corruption (fast): 0x0000000000ee0b10 *** While this code is fixable, the commit itself fails on several levels: - it should have been a separate helper function - why the heck does it do strchr() twice - it casts a const char * over into char * - sloppy style - it's not even a regression fix! So lets revert it and re-try the patch in v3.13.

Specifics: 1) After the recent locking changes in the cpufreq core it is possible to trigger BUG_ON(!policy) in lock_policy_rwsem_read() if cpufreq_get() is called before registering a cpufreq driver. Fix from Viresh Kumar. 2) If intel_pstate has been loaded already, it doesn't make sense to do anything in acpi_cpufreq_init() and moreover doing something in there in that case may be harmful, so make that function return immediately if another cpufreq driver is already present. From Yinghai Lu. 3) The ACPI IPMI driver sometimes attempts to acquire a mutex from interrupt context, which can be avoided by replacing that mutex with a spinlock. From Lv Zheng. 4) A NULL pointer may be dereferenced by the exynos5440 cpufreq driver if a memory allocation made by it fails. Fix from Sachin Kamat. 5) Hanjun Guo's commit fixes a typo in the kerneldoc comment documenting acpi_bus_unregister_driver()" * tag 'pm+acpi-3.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / scan: fix typo in comments of acpi_bus_unregister_driver() cpufreq: exynos5440: Fix potential NULL pointer dereference cpufreq: check cpufreq driver is valid and cpufreq isn't disabled in cpufreq_get() acpi-cpufreq: skip loading acpi_cpufreq after intel_pstate ACPI / IPMI: Fix atomic context requirement of ipmi_msg_handler()
2013-09-28PCI: Workaround missing pci_set_master in pci driversYinghai Lu
Ben Herrenschmidt found that commit 928bea964827 ("PCI: Delay enabling bridges until they're needed") breaks PCI in some powerpc environments. The reason is that the PCIe port driver will call pci_enable_device() on the bridge, so the device is enabled, but skips pci_set_master because pcie_port_auto and no acpi on powerpc. Because of that, pci_enable_bridge() later on (called as a result of the child device driver doing pci_enable_device) will see the bridge as already enabled and will not call pci_set_master() on it. Fixed by add checking in pci_enable_bridge, and call pci_set_master if driver skip that. That will make the code more robot and wade off problem for missing pci_set_master in drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 lockref enablement from Heiko Carstens: "Enabling the new lockless lockref variant on s390 would have been trivial until Tony Luck added a cpu_relax() call into the CMPXCHG_LOOP(), with commit d472d9d98b46 ("lockref: Relax in cmpxchg loop") As already mentioned cpu_relax() is very expensive on s390 since it yields() the current virtual cpu. So we are talking of several thousand cycles. Considering this enabling the lockless lockref variant would contradict the intention of the new semantics. And also some quick measurements show performance regressions of 50% and more. Simply removing the cpu_relax() call again seems also not very desireable since Waiman Long reported that for some workloads the call improved performance by 5%." * 'lockref' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390: enable ARCH_USE_CMPXCHG_LOCKREF lockref: use arch_mutex_cpu_relax() in CMPXCHG_LOOP() mutex: replace CONFIG_HAVE_ARCH_MUTEX_CPU_RELAX with simple ifdef

Make use of arch_mutex_cpu_relax() so architectures can override the default cpu_relax() semantics.

In kobj_ns_current_may_mount the default should be to allow the mount. The test is only for a single kobj_ns_type at a time, and unless there is a reason to prevent it the mounting sysfs should be allowed. Subsystems that are not registered can't have are not involved so can't have a reason to prevent mounting sysfs.

2013-09-27lockref: allow relaxed cmpxchg64 variant for lockless updatesWill Deacon
The 64-bit cmpxchg operation on the lockref is ordered by virtue of hazarding between the cmpxchg operation and the reference count manipulation. On weakly ordered memory architectures (such as ARM), it can be of great benefit to omit the barrier instructions where they are not needed. This patch moves the lockless lockref code over to a cmpxchg64_relaxed operation, which doesn't provide barrier semantics. If the operation isn't defined, we simply #define it as the usual 64-bit cmpxchg macro.

2013-09-27i2c: designware: 10-bit addressing mode enabling if I2C_DYNAMIC_TAR_UPDATE ↵Chew, Chiau Ee
is set According to Designware I2C spec, if I2C_DYNAMIC_TAR_UPDATE is set to 1, the 10-bit addressing mode is controlled by IC_10BITADDR_MASTER bit of IC_TAR register instead of IC_CON register. The IC_10BITADDR_MASTER in IC_CON register becomes read-only copy. Since I2C_DYNAMIC_TAR_UPDATE value can't be detected from hardware register, so we will always set the IC_10BITADDR_MASTER bit in both IC_CON and IC_TAR register whenever 10-bit addresing mode is requested by user application.

2013-09-27arm: Fix build error with context tracking callsFrederic Weisbecker
ad65782fba50 (context_tracking: Optimize main APIs off case with static key) converted context tracking main APIs to inline function and left ARM asm callers behind. This can be easily fixed by making ARM calling the post static keys context tracking function. We just need to replicate the static key checks there. We'll remove these later when ARM will support the context tracking static keys.

2013-09-27x86/microcode/AMD: Fix patch level reporting for family 15hSuravee Suthikulpanit
On AMD family 14h, applying microcode patch on the a core (core0) would also affect the other core (core1) in the same compute unit. The driver would skip applying the patch on core1, but it still need to update kernel structures to reflect the proper patch level. The current logic is not updating the struct ucode_cpu_info.cpu_sig.rev of the skipped core. This causes the /sys/devices/system/cpu/cpu1/microcode/version to report incorrect patch level as shown below: $ grep . cpu?/microcode/version cpu0/microcode/version:0x600063d cpu1/microcode/version:0x6000626 cpu2/microcode/version:0x600063d cpu3/microcode/version:0x6000626 cpu4/microcode/version:0x600063d Signed-off-by: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com> Acked-by: Borislav Petkov <bp@suse.de> Cc: <bp@alien8.de> Cc: <jacob.w.shin@gmail.com> Cc: <herrmann.der.user@googlemail.com> Link: http://lkml.kernel.org/r/1285806432-1995-1-git-send-email-suravee.suthikulpanit@amd.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
