2015-01-08Makefile: include arch/*/include/generated/uapi before .../generatedMichal Marek1-0/+1
The introduction of the uapi directories in v3.7-rc1 moved some of the generated headers from arch/*/include/generated to the uapi directory, keeping the #include directives intact. This creates a problem when bisecting, because the unversioned files are not cleaned automatically by git and the compiler might include stale headers as a result. Instead of cleaning them in the Makefiles, promote arch/*/include/generated/uapi in the search path. Under normal circumstances, there is no overlap between this uapi subdirectory and its parent, so the include choices remain the same. We keep arch/*/include/generated/uapi in the USERINCLUDE variable so that it is usable standalone. Note that we cannot completely swap the order of the uapi and kernel-only directories, since the headers in include/uapi/asm-generic are meant to be wrapped by their include/asm-generic counterparts when building kernel code.

2015-01-08NVMe: Admin queue removal handlingKeith Busch1-14/+20
This protects admin queue access on shutdown. When the controller is disabled, the queue is frozen to prevent new entry, and unfrozen on resume, and fixes cq_vector signedness to not suspend a queue twice. Since unfreezing the queue makes it available for commands, it requires the queue be initialized, so this moves this part after that. Special handling is done when the device is unresponsive during shutdown. This can be optimized to not require subsequent commands to timeout, but saving that fix for later. This patch also removes the kill signals in this path that were left-over artifacts from the blk-mq conversion and no longer necessary.

2015-01-08NVMe: Start all requestsKeith Busch1-4/+12

For timed out commands on a device that is not initialized, this fixes potential deadlocks that can occur on startup and shutdown when a device is unresponsive since they can now be cancelled. Asynchronous requests do not have any expected timeout, so these are using the new "REQ_NO_TIMEOUT" request flags.

2015-01-08libata: Whitelist SSDs that are known to properly return zeroes after TRIMMartin K. Petersen3-8/+34
As defined, the DRAT (Deterministic Read After Trim) and RZAT (Return Zero After Trim) flags in the ATA Command Set are unreliable in the sense that they only define what happens if the device successfully executed the DSM TRIM command. TRIM is only advisory, however, and the device is free to silently ignore all or parts of the request. In practice this renders the DRAT and RZAT flags completely useless and because the results are unpredictable we decided to disable discard in MD for 3.18 to avoid the risk of data corruption. Hardware vendors in the real world obviously need better guarantees than what the standards bodies provide. Unfortuntely those guarantees are encoded in product requirements documents rather than somewhere we can key off of them programatically. So we are compelled to disabling discard_zeroes_data for all devices unless we explicitly have data to support whitelisting them. This patch whitelists SSDs from a few of the main vendors. None of the whitelists are based on written guarantees. They are purely based on empirical evidence collected from internal and external users that have tested or qualified these drives in RAID deployments. The whitelist is only meant as a starting point and is by no means comprehensive: - All intel SSD models except for 510 - Micron M5?0/M600 - Samsung SSDs - Seagate SSDs Signed-off-by: Martin K.

So fix its check before comparing the callchain depth. This also changes the hist accumulation tests: In test 3, xmalloc in bash thread should be above than other perf threads due to alphabetical order of comm string. Also it's under page_fault in bash thread since alphabetical order of dso name. The sys_perf_event_open in perf thread is put on the last line since it's self overhead is 0.

The early ioremap support introduced by patch bf4b558eba92 ("arm64: add early_ioremap support") failed to add a call to early_ioremap_reset() at an appropriate time. Without this call, invocations of early_ioremap etc. that are done too late will go unnoticed and may cause corruption. This is exactly what happened when the first user of this feature was added in patch f84d02755f5a ("arm64: add EFI runtime services"). The early mapping of the EFI memory map is unmapped during an early initcall, at which time the early ioremap support is long gone. Fix by adding the missing call to early_ioremap_reset() to setup_arch(), and move the offending early_memunmap() to right after the point where the early mapping of the EFI memory map is last used.

git://people.freedesktop.org/~gabbayo/linux into drm-fixes - Complete overhaul to the main IOCTL function, kfd_ioctl(), according to drm_ioctl() example. This includes changing the IOCTL definitions, so it breaks compatibility with previous versions of the userspace. However, because the kernel was not officialy released yet, and this the first kernel that includes amdkfd, I assume I can still do that at this stage. - A couple of bug fixes for the non-HWS path (used for bring-ups and debugging purposes only). * tag 'amdkfd-fixes-2015-01-06' of git://people.freedesktop.org/~gabbayo/linux: drm/amdkfd: rewrite kfd_ioctl() according to drm_ioctl() drm/amdkfd: reformat IOCTL definitions to drm-style drm/amdkfd: Do copy_to/from_user in general kfd_ioctl() drm/amdkfd: unmap VMID<-->PASID when relesing VMID (non-HWS) drm/radeon: Assign VMID to PASID for IH in non-HWS mode drm/radeon: do not leave queue acquired if timeout happens in kgd_hqd_destroy() drm/amdkfd: Load mqd to hqd in non-HWS mode drm/amd: Fixing typos in kfd<->kgd interface

2015-01-08ARM: shmobile: sh73a0 legacy: Set .control_parent for all irqpin instancesGeert Uytterhoeven1-0/+3
The sh73a0 INTC can't mask interrupts properly most likely due to a hardware bug. Set the .control_parent flag to delegate masking to the parent interrupt controller, like was already done for irqpin1. Without this, accessing the three-axis digital accelerometer ADXL345 on kzm9g through /dev/input/event1 causes an interrupt storm, which requires a power-cycle to recover from. This was inspired by a patch for arch/arm/boot/dts/sh73a0.dtsi from Laurent Pinchart <[email protected]>.
