2014-12-29shm: add memfd_create() syscallDavid Herrmann2-0/+2
memfd_create() is similar to mmap(MAP_ANON), but returns a file-descriptor that you can pass to mmap(). It can support sealing and avoids any connection to user-visible mount-points. Thus, it's not subject to quotas on mounted file-systems, but can be used like malloc()'ed memory, but with a file-descriptor to it. memfd_create() returns the raw shmem file, so calls like ftruncate() can be used to modify the underlying inode. Also calls like fstat() will return proper information and mark the file as regular file. If you want sealing, you can specify MFD_ALLOW_SEALING. Otherwise, sealing is not supported (like on all other regular files). Compared to O_TMPFILE, it does not require a tmpfs mount-point and is not subject to a filesystem size limit. It is still properly accounted to memcg limits, though, and to the same overcommit or no-overcommit accounting as all user memory.

2014-12-24ARM: exynos: add support secondary core bootup in big.LITTLE processor.Hyungwon Hwang3-15/+26
This patch adds support secondary core bootup in big.LITTLE processor for platsmp. Just core id cannot be used for identification, because there is a pair of the cores which have same core id. Cluster id have to be included for their identification. This patch makes cpu index using cluster id and core id for the calculation of their register address and the identification. But there is a problem to use cluster id for core index creation. That is, cluster id does not start from 0 in old processors which do not have more than one cluster. For example, Exynos4412's cluster id for its 4 core is 0xa. So I makes all cluster id to 0 when they are bigger than 1. Normally big.LITTLE processor does not use platsmp. But at this moment, just for the minimal functionality of big.LITTLE, this patch adds support for it. This patch can be reverted after another CPU management method is adopted.

2014-12-17ARM: dts: remove display power domain for exynos5420Rahul Sharma1-6/+0
Display domain is removed due to instability issues. Explaining the problem below: exynos_init_late triggers the pm_genpd_poweroff_unused which powers off the unused power domains. This call hits before the trigger to deferred probes. DRM DP Panel defers the probe due to supply get failure. By the time, deferred probe is scheduled again, Display Power Domain is powered off by pm_genpd_poweroff_unused. FIMD and DP drivers are accessing registers during Probe and Bind callbacks. If display domain is enabled/disabled around register accesses, display domain gets unstable and we are getting Power Domain Disable fail notification. Increasing the Timeout also didn't help.

G2D power domain also controls the CMU block of G2D. Since clock registers can be accessed anytime for viewing clk_summary, it can cause a system crash if g2d power domain is disabled. Signed-off-by: Arun Kumar K <arun.kk@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
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>
2014-12-17ARM: dts: disable MDMA1 node for exynos5420Seungwon Jeon1-0/+7
This change places MDMA1 in disabled node for Exynos5420. If MDMA1 region is configured with secure mode, it makes the boot failure with the following on smdk5420 board. ("Unhandled fault: imprecise external abort (0x1406) at 0x00000000") Thus, arndale-octa board don't need to do the same thing anymore.
