If neither CONFIG_SUSPEND nor CONFIG_CPU_IDLE is set in the kernel
configuration file, build error occurs in
arch/arm/mach-shmobile/pm-sh7372.c.
Fix it by rearranging #ifdefs in that file to make the
definition of sh7372_suspend_init() depend only on
CONFIG_SUSPEND and the definition of sh7372_cpuidle_init()
depend only on CONFIG_CPU_IDLE.

ARM: shmobile: Take cpuidle dependencies into account correctly
The sh7372's cpuidle code uses cpu_suspend() and cpu_resume() in
its implementation of the .enter() callback for deeper C-states, so
make ARCH_SH7372 select ARM_CPU_SUSPEND if CPU_IDLE is set to satisfy
all of the build dependencies (it has to be selected for CONFIG_PM
as well for the system suspend handling).

We can control renesas_usbhs driver as 2 way which are
autonomy mode and external IRQ trigger mode.
Autonomy mode is very easy settings for platform,
but it required USB power domain always ON,
since its connection/disconnection IRQ come from it.
If platform uses external IRQ trigger mode,
USB power domain can be OFF, since its

ARM: mach-shmobile: select the fixed regulator driver on several boards
On systems, using regulators to supply power to devices, if the REGULATOR
Kconfig option is disabled, regulator API stubs will be used, which often
suffices to bring a default configuration up. If REGULATOR is enabled but
respective regulator drivers are inactive, the real regulator API calls
will be used, which in the absence of drivers will fail to provide
services. This patch prevents such a problem on sh-mobile boards by
forcing REGULATOR_FIXED_VOLTAGE on if REGULATOR is selected.

ARM: mach-shmobile: add missing GPIO IRQ configuration on mackerel
SDHI0 card-detect GPIO IRQ on mackarel currently works, because it is the
default configuration of IRQ26. However, we should not rely on this and
should configure the function explicitly.

This is the cause by when EMEV2 is disabled, that the check by OF of EMEV2 is
performed in platsmp.c.
This patch revise what the function about EMEV2 may not be used in this file,
when EMEV2 is not enabled.

chclr_write() will use (chan_reg + chclr_offset).
In sh7372 case, DMA1CHCLR is started from 0xfe008220,
and chan_reg is started from 0xfe008020 (= sh7372_dmae0_resources).
Thus, chclr_offset should be (0x220 - 0x20) instead of 0x220.

regulator: support multiple dummy fixed regulators
Currently regulator_register_fixed() uses a constant name to register a
fixed dummy regulator. This is sufficient in principle, since there is no
reason to register multiple such regulators. The user can simply supply all
consumers in one array and use it to initialise such a regulator. However,
in some cases it can be convenient to register multiple such regulators.
This is also a prerequisite for the upcoming patch, that will add a voltage
parameter to this function. The original function is provided as a wrapper
macro.

tile: fix bug in get_user() for 4-byte values
The definition of 32-bit values in the 64-bit tilegx architecture is that
they should be sign-extended regardless of whether they are considered
signed or unsigned by the compiler. Accordingly, we need to use an
"ld4s" rather than "ld4u" to load and sign-extend for get_user().
This fixes glibc bug 14238 (see http://sourceware.org/bugzilla),
introduced during the 3.5 merge window.

swap: fix shmem swapping when more than 8 areas
Minchan Kim reports that when a system has many swap areas, and tmpfs
swaps out to the ninth or more, shmem_getpage_gfp()'s attempts to read
back the page cannot locate it, and the read fails with -ENOMEM.
Whoops. Yes, I blindly followed read_swap_header()'s pte_to_swp_entry(
swp_entry_to_pte()) technique for determining maximum usable swap
offset, without stopping to realize that that actually depends upon the
pte swap encoding shifting swap offset to the higher bits and truncating
it there. Whereas our radix_tree swap encoding leaves offset in the
lower bits: it's swap "type" (that is, index of swap area) that was
truncated.
Fix it by reducing the SWP_TYPE_SHIFT() in swapops.h, and removing the
broken radix_to_swp_entry(swp_to_radix_entry()) from read_swap_header().
This does not reduce the usable size of a swap area any further, it
leaves it as claimed when making the original commit: no change from 3.0
on x86_64, nor on i386 without PAE; but 3.0's 512GB is reduced to 128GB
per swapfile on i386 with PAE. It's not a change I would have risked
five years ago, but with x86_64 supported for ten years, I believe it's
appropriate now.
Hmm, and what if some architecture implements its swap pte with offset
encoded below type? That would equally break the maximum usable swap
offset check. Happily, they all follow the same tradition of encoding
offset above type, but I'll prepare a check on that for next.
