79f211b8e1 sh64: wire up sys_accept4.
sh64 on the other hand provides both direct broken out syscalls as well
as socketcall access. As there are binaries that use both socketcall has
to stay around. The current ABI prefers direct syscalls.

It was pointed out that when sys_recvmmsg was added in, sys_accept4 was
overlooked. This takes care of wiring it up.

6eacb2c4cb sh: unwire sys_recvmmsg.
sh32 at the moment only uses sys_socketcall to reach these, so unwire
recvmmsg for now. While we're at it, add it to the ignore list, as per
the s390 change.

8152a74bc0 sh: Only provide a PCLK definition for legacy CPG CPUs.
As CPUs are migrated over to more fully-featured clock frameworks of
their own and off of the legacy CPG code, they no longer have any real
need for defining the PCLK value. The PCLK define in itself is already
fairly misleading, as many boards get their input clocks from different
sources, making this value fairly arbitrary anyways.

Outside of the legacy CPG clock framework, the only place where this
value is used is for deriving CLOCK_TICK_RATE, which we set back to the
legacy PIT value that it was before the PCLK definitions were added in
the first place.

2f7bb2dfed sh: Fix up MAX_DMA_CHANNELS definition when DMA is disabled.
MAX_DMA_CHANNELS is tested for the total number of channels in order to
populate an IRQ map. Stub this out completely when no DMA support is
enabled -- as used to be the default behaviour before this was
generalized for use by the dmaengine code.

445c89514b locking: Convert raw_spinlock to arch_spinlock
The raw_spin* namespace was taken by lockdep for the architecture
specific implementations. raw_spin_* would be the ideal name space for
the spinlocks which are not converted to sleeping locks in preempt-rt.

Linus suggested to convert the raw_ to arch_ locks and cleanup the
name space instead of using an artifical name like core_spin,
atomic_spin or whatever

No functional change.

fcb4ebd678 sh: Couple kernel and user write page perm bits for CONFIG_X2TLB
pte_write() should check whether the permissions include either the user
or kernel write permission bits. Likewise, pte_wrprotect() needs to
remove both the kernel and user write bits.

Without this patch handle_tlbmiss() doesn't handle faulting in pages
from the P3 area (our vmalloc space) because of a write. Mappings of the
P3 space have the _PAGE_EXT_KERN_WRITE bit but not _PAGE_EXT_USER_WRITE.

559df2e021 kbuild: move asm-offsets.h to include/generated
The simplest method was to add an extra asm-offsets.h
file in arch/$ARCH/include/asm that references the generated file.

We can now migrate the architectures one-by-one to reference
the generated file direct - and when done we can delete the
temporary arch/$ARCH/include/asm/asm-offsets.h file.

657bf0bd06 sh: LCDC start_transfer() for the KFR2R09 board
This patch adds a ->start_transfer() callback to the
KFR2R09 lcd handling code. The callback is used to
notify the lcd controller that a new frame of data
is about to be transferred. The callback is only used
in combination with deferred io, but the code has
been tested both with and without deferred io enabled.

Without this patch the display data on the KFR2R09
lcd panel becomes corrupted over time.
