Tomasz Figa 0a90d4d62c ARM: S5PV210: Untie PM support from legacy code
This patch makes S5PV210 not rely on legacy suspend helpers in
plat-samsung and implements platform suspend logic locally, similarly to
Exynos.

Tomasz Figa 28c8331d38 ARM: S5PV210: Remove support for board files
Since all in-tree boards have been moved to device tree, we can now drop
legacy code and make mach-s5pv210 DT-only. This patch does it.

Pankaj Dubey b634e38f31 ARM: EXYNOS: Remove regs-pmu.h header dependency from pm_domain
Current "pm_domain.c" file uses "S5P_INT_LOCAL_PWR_EN" definition from
"regs-pmu.h" and hence needs to include this header file. As there is
no other user of "S5P_INT_LOCAL_PWR_EN" definition other than pm_domain,
to remove "regs-pmu.h" header file dependency from "pm_domain.c"  it's
better we define this definition in "pm_domain.c" file itself and thus it
will help in removing header file inclusion from "pm_domain.c".
Also removing "S5P_" prefix from macro.

Thomas Gleixner 449437778b clk: spear3xx: Set proper clock parent of uart1/2
The uarts only work when the parent is ras_ahb_clk. The stale 3.5
based ST tree does this in the board file.

Add it to the clk init function. Not pretty, but the mess there is
amazing anyway.

The control register is at offset 0x10, not 0x0. This is wreckaged

Helge Deller ab8a261ba5 parisc: fix fanotify_mark() syscall on 32bit compat kernel
On parisc we can not use the existing compat implementation for fanotify_mark()
because for the 64bit mask parameter the higher and lower 32bits are ordered
differently than what the compat function expects from big endian
architectures.

Specifically:
It finally turned out, that on hppa we end up with different assignments
of parameters to kernel arguments depending on if we call the glibc
wrapper function
 int fanotify_mark (int __fanotify_fd, unsigned int __flags,
                    uint64_t __mask, int __dfd, const char *__pathname);
or directly calling the syscall manually
 syscall(__NR_fanotify_mark, ...)

Reason is, that the syscall() function is implemented as C-function and
because we now have the sysno as first parameter in front of the other
parameters the compiler will unexpectedly add an empty paramenter in
front of the u64 value to ensure the correct calling alignment for 64bit
values.
This means, on hppa you can't simply use syscall() to call the kernel
fanotify_mark() function directly, but you have to use the glibc
function instead.

This patch fixes the kernel in the hppa-arch specifc coding to adjust
the parameters in a way as if userspace calls the glibc wrapper function
fanotify_mark().

- update the parent for Auudss clock because kernel will be hang
   during late boot if the parent clock is disabled in bootloader.
 - enable clk handing in power domain because while power domain
   on/off, its regarding clock source will be reset and it causes
   a problem so need to handle it.
 - add mux clocks to be used by power domain for exynos5420-mfc
   during power domain on/off and property in device tree also.
 - register cpuidle only for exynos4210 and exynos5250 because a
   system failure will be happened on other exynos SoCs.

Dell kernel driver dell-smo8800 provides same freefall interface as hp_accel so
program hpfall.c works also on Dell laptops. So rename it to freefall.c.

Dell driver does not provide hp::hddprotect led so make sure that freefall.c
works also if hp::hddprotect does not exist in sysfs.

Additionally write info to syslog.
