370f06c Madhavan Srinivasan 25 January 2016, 08:33:46 UTC powerpc/perf: Remove PPMU_HAS_SSLOT flag for Power8 Commit 7a7868326d77 ("powerpc/perf: Add an explict flag indicating presence of SLOT field") introduced the PPMU_HAS_SSLOT flag to remove the assumption that MMCRA[SLOT] was present when PPMU_ALT_SIPR was not set. That commit's changelog also mentions that Power8 does not support MMCRA[SLOT]. However when the Power8 PMU support was merged, it errnoeously included the PPMU_HAS_SSLOT flag. So remove PPMU_HAS_SSLOT from the Power8 flags. mpe: On systems where MMCRA[SLOT] exists, the field occupies bits 37:39 (IBM numbering). On Power8 bit 37 is reserved, and 38:39 overlap with the high bits of the Threshold Event Counter Mantissa. I am not aware of any published events which use the threshold counting mechanism, which would cause the mantissa bits to be set. So in practice this bug is unlikely to trigger.

7ee9621 Takashi Iwai 28 January 2016, 06:54:16 UTC ALSA: dummy: Disable switching timer backend via sysfs ALSA dummy driver can switch the timer backend between system timer and hrtimer via its hrtimer module option. This can be also switched dynamically via sysfs, but it may lead to a memory corruption when switching is done while a PCM stream is running; the stream instance for the newly switched timer method tries to access the memory that was allocated by another timer method although the sizes differ. As the simplest fix, this patch just disables the switch via sysfs by dropping the writable bit.

The power on phase of a genpd starts by acquiring its lock. Then it walks the hierarchy of its parent domains to be able to power on these first, as per design of genpd. From a locking perspective this means the locks of the parents becomes acquired after the lock of the subdomain. Let's fix pm_genpd_add|remove_subdomain() to maintain the same order of acquiring/releasing the genpd lock as being applied in the power on/off sequence.

13b4389 Alan Stern 20 January 2016, 16:26:01 UTC SCSI: fix crashes in sd and sr runtime PM Runtime suspend during driver probe and removal can cause problems. The driver's runtime_suspend or runtime_resume callbacks may invoked before the driver has finished binding to the device or after the driver has unbound from the device. This problem shows up with the sd and sr drivers, and can cause disk or CD/DVD drives to become unusable as a result. The fix is simple. The drivers store a pointer to the scsi_disk or scsi_cd structure as their private device data when probing is finished, so we simply have to be sure to clear the private data during removal and test it during runtime suspend/resume.

9abc2a0 David Hildenbrand 14 January 2016, 21:12:47 UTC KVM: s390: fix memory overwrites when vx is disabled The kernel now always uses vector registers when available, however KVM has special logic if support is really enabled for a guest. If support is disabled, guest_fpregs.fregs will only contain memory for the fpu. The kernel, however, will store vector registers into that area, resulting in crazy memory overwrites. Simply extending that area is not enough, because the format of the registers also changes. We would have to do additional conversions, making the code even more complex. Therefore let's directly use one place for the vector/fpu registers + fpc (in kvm_run). We just have to convert the data properly when accessing it. This makes current code much easier. Please note that vector/fpu registers are now always stored to vcpu->run->s.regs.vrs. Although this data is visible to QEMU and used for migration, we only guarantee valid values to user space when KVM_SYNC_VRS is set. As that is only the case when we have vector register support, we are on the safe side.

67dfa17 dann frazier 25 January 2016, 23:52:16 UTC arm64: errata: Add -mpc-relative-literal-loads to build flags GCC6 (and Linaro's 2015.12 snapshot of GCC5) has a new default that uses adrp/ldr or adrp/add to address literal pools. When CONFIG_ARM64_ERRATUM_843419 is enabled, modules built with this toolchain fail to load: module libahci: unsupported RELA relocation: 275 This patch fixes the problem by passing '-mpc-relative-literal-loads' to the compiler.

728dabd William Cohen 22 January 2016, 03:56:26 UTC Eliminate the .eh_frame sections from the aarch64 vmlinux and kernel modules By default the aarch64 gcc generates .eh_frame sections. Unlike .debug_frame sections, the .eh_frame sections are loaded into memory when the associated code is loaded. On an example kernel being built with this default the .eh_frame section in vmlinux used an extra 1.7MB of memory. The x86 disables the creation of the .eh_frame section. The aarch64 should probably do the same to save some memory. Signed-off-by: William Cohen <wcohen@redhat.com> Signed-off-by: Will Deacon <will.deacon@arm.com> 26 January 2016, 11:14:13 UTC
0790529 Lucas Tanure 25 January 2016, 21:30:23 UTC ALSA: bebob: Use a signed return type for get_formation_index The return type "unsigned int" was used by the get_formation_index function despite of the aspect that it will eventually return a negative error code. So, change to signed int and get index by reference in the parameters. Done with the help of Coccinelle.

481eaec Michael S. Tsirkin 21 January 2016, 12:44:10 UTC tools/virtio: add ringtest utilities This adds micro-benchmarks useful for tuning virtio ring layouts. Three layouts are currently implemented: - virtio 0.9 compatible one - an experimental extension bypassing the ring index, polling ring itself instead - an experimental extension bypassing avail and used ring completely Typical use: sh run-on-all.sh perf stat -r 10 --log-fd 1 -- ./ring It doesn't depend on the kernel directly, but it's handy to have as much virtio stuff as possible in one tree.
