2014-12-17ARM: dts: Remove mau_pd node for exynos5420Tushar Behera1-5/+0
MAU powerdomain provides clocks for Audio sub-system block. This block comprises of the I2S audio controller, audio DMA blocks and Audio sub-system clock registers. Right now, there is no way to hook up power-domains with clock providers. During late boot when this power-domain gets disabled, we get following external abort. Unhandled fault: imprecise external abort (0x1406) at 0x00000000 Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000007 Signed-off-by: Tushar Behera <tushar.behera@linaro.org> Tested-by: Doug Anderson <dianders@chromium.org> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

2014-11-21seqcount: Add lockdep functionality to seqcount/seqlock structuresJohn Stultz1-4/+4
Currently seqlocks and seqcounts don't support lockdep. After running across a seqcount related deadlock in the timekeeping code, I used a less-refined and more focused variant of this patch to narrow down the cause of the issue. This is a first-pass attempt to properly enable lockdep functionality on seqlocks and seqcounts. Since seqcounts are used in the vdso gettimeofday code, I've provided non-lockdep accessors for those needs. I've also handled one case where there were nested seqlock writers and there may be more edge cases. Comments and feedback would be appreciated!
