2017-03-02selftests: lib.mk Fix individual test buildsShuah Khan1-0/+4
In commit a8ba798bc8ec ("selftests: enable O and KBUILD_OUTPUT"), added support to generate compile targets in a user specified directory. OUTPUT variable controls the location which is undefined when tests are built in the test directory or with "make -C tools/testing/selftests/x86". make -C tools/testing/selftests/x86/ make: Entering directory '/lkml/linux_4.11/tools/testing/selftests/x86' Makefile:44: warning: overriding recipe for target 'clean' ../lib.mk:51: warning: ignoring old recipe for target 'clean' gcc -m64 -o /single_step_syscall_64 -O2 -g -std=gnu99 -pthread -Wall single_step_syscall.c -lrt -ldl /usr/bin/ld: cannot open output file /single_step_syscall_64: Permission denied collect2: error: ld returned 1 exit status Makefile:50: recipe for target '/single_step_syscall_64' failed make: *** [/single_step_syscall_64] Error 1 make: Leaving directory '/lkml/linux_4.11/tools/testing/selftests/x86' Same failure with "cd tools/testing/selftests/x86/;make" run. Fix this with a change to lib.mk to define OUTPUT to be the pwd when MAKELEVEL is 0. This covers both cases mentioned above.

2017-03-02drm/i915: Fix legacy cursor vs. watermarks for ILK-BDWVille Syrjälä2-19/+30
In order to make cursor updates actually safe wrt. watermark programming we have to clear the legacy_cursor_update flag in the atomic state. That will cause the regular atomic update path to do the necessary vblank wait after the plane update if needed, otherwise the vblank wait would be skipped and we'd feed the optimal watermarks to the hardware before the plane update has actually happened. To make the slow vs. fast path determination in intel_legacy_cursor_update() a little simpler we can ignore the actual visibility of the plane (which can only get computed once we've already chosen out path) and instead we simply check whether the fb is being set or cleared by the user. This means a fully clipped but logically visible cursor will be considered visible as far as watermark programming is concerned. We can do that for the cursor since it's a fixed size plane and the clipped size doesn't play a role in the watermark computation. This should fix underruns that can occur when the cursor gets enable/disabled or the size gets changed. Hopefully it's good enough that only pure cursor movement and flips go through unthrottled.

2017-03-02ath10k: search SMBIOS for OEM board file extensionWaldemar Rymarkiewicz2-3/+117
Board Data File (BDF) is loaded upon driver boot-up procedure. The right board data file is identified, among others, by device and sybsystem ids. The problem, however, can occur when the (default) board data file cannot fulfill with the vendor requirements and it is necessary to use a different board data file. To solve the issue QCA uses SMBIOS type 0xF8 to store Board Data File Name Extension to specify the extension/variant name. The driver will take the extension suffix into consideration and will load the right (non-default) board data file if necessary. If it is unnecessary to use extension board data file, please leave the SMBIOS field blank and default configuration will be used. Example: If a default board data file for a specific board is identified by a string "bus=pci,vendor=168c,device=003e,subsystem-vendor=1028, subsystem-device=0310" then the OEM specific data file, if used, could be identified by variant suffix: "bus=pci,vendor=168c,device=003e,subsystem-vendor=1028, subsystem-device=0310,variant=DE_1AB" If board data file name extension is set but board-2.bin does not contain board data file for the variant, the driver will fallback to the default board data file not to break backward compatibility. This was first applied in commit f2593cb1b291 ("ath10k: Search SMBIOS for OEM board file extension") but later reverted in commit 005c3490e9db ("Revert "ath10k: Search SMBIOS for OEM board file extension"". This patch is now otherwise the same as commit f2593cb1b291 except the regression fixed.

2017-03-02sched/headers: Move scheduler topology interfaces to <linux/sched/topology.h>Ingo Molnar2-212/+213
The vast majority of sched.h users does not require the topology types and interfaces, so split them out into <linux/sched/topology.h>. This reduces the size of linux/sched.h by ~6%.

2017-03-02sched/headers: Prepare to remove spurious <linux/sched.h> inclusion dependenciesIngo Molnar4-0/+4
In the following patches we are going to remove various headers from sched.h and other headers that sched.h includes. To make those patches build cleanly prepare the scene by adding dependencies to various files that learned to rely on those to-be-removed dependencies. These changes all make sense standalone: they add a header for a data type that a particular .c or .h file is using.
