      selftests/powerpc: Specify we expect to build with std=gnu99 · ca49e64f
      由 Michael Ellerman 提交于 
      We have some tests that assume we're using std=gnu99, which is fine on
most compilers, but some old compilers use a different default.

So make it explicit that we want to use std=gnu99.

      ALSA: hda - Manage power well properly for resume · a52ff34e
      由 Takashi Iwai 提交于 
      For SKL and later Intel chips, we control the power well per codec
basis via link_power callback since the commit [03b135ce: ALSA:
hda - remove dependency on i915 power well for SKL].
However, there are a few exceptional cases where the gfx registers are
accessed from the audio driver: namely the wakeup override bit
toggling at (both system and runtime) resume.  This seems causing a
kernel warning when accessed during the power well down (and likely
resulting in the bogus register accesses).

This patch puts the proper power up / down sequence around the resume
code so that the wakeup bit is fiddled properly while the power is
up.  (The other callback, sync_audio_rate, is used only in the PCM
callback, so it's guaranteed in the power-on.)

Also, by this proper power up/down, the instantaneous flip of wakeup
bit in the resume callback that was introduced by the commit
[033ea349: ALSA: hda - Fix Skylake codec timeout] becomes
superfluous, as snd_hdac_display_power() already does it.  So we can
clean it up together.

      powerpc/vdso: Fix build rules to rebuild vdsos correctly · b9a4a0d0
      由 Nicholas Piggin 提交于 
      When using if_changed, we need to add FORCE as a dependency (see
Documentation/kbuild/makefiles.txt) otherwise we don't get command line
change checking amongst other things. This has resulted in vdsos not
being rebuilt when switching between big and little endian.

The vdso64/32ld commands have to be changed around to avoid pulling
FORCE into the linker command line (code copied from x86).

      powerpc/Makefile: Use cflags-y/aflags-y for setting endian options · 164af597
      由 Michael Ellerman 提交于 
      When we introduced the little endian support, we added the endian flags
to CC directly using override. I don't know the history of why we did
that, I suspect no one does.

Although this mostly works, it has one bug, which is that CROSS32CC
doesn't get -mbig-endian. That means when the compiler is little endian
by default and the user is building big endian, vdso32 is incorrectly
compiled as little endian and the kernel fails to build.

Instead we can add the endian flags to cflags-y/aflags-y, and then
append those to KBUILD_CFLAGS/KBUILD_AFLAGS.

This has the advantage of being 1) less ugly, 2) the documented way of
adding flags in the arch Makefile and 3) it fixes building vdso32 with a
LE toolchain.
