This patch adds initial support for Renesas SH-Mobile AG5.
At this point the AG5 CPU support is limited to the ARM
core, SCIF serial and a CMT timer together with L2 cache
and the GIC. The AG5EVM board also supports Ethernet.
Future patches will add support for GPIO, INTCS, CPGA
and platform data / driver updates for devices such as
IIC, LCDC, FSI, KEYSC, CEU and SDHI among others.
The code in entry-macro.S will be cleaned up when the
ARM IRQ demux code improvements have been merged.
Depends on the AG5EVM mach-type recently registered but
not yet present in arch/arm/tools/mach-types.
As the AG5EVM board comes with 512MiB memory it is
recommended to turn on HIGHMEM.
Many thanks to Yoshii-san for initial bring up.

Presently each one of the CPUs manually selects the same feature set, and
there's a reasonable expectation that none of these will change for
future CPUs in the SH-Mobile / R-Mobile family, so we move those over to
the top-level ARCH_SHMOBILE.
While we're at it, all of the CPUs support optional GPIOs via the PFC,
do not have I/O ports, and expect sparse IRQ, so we bring the
configuration in line across the board.
This more or less brings the ARM-based parts in sync with their SH
counterparts.

The addition of CONFIG_SECURITY_DMESG_RESTRICT resulted in a build
failure when CONFIG_PRINTK=n. This is because the capabilities code
which used the new option was built even though the variable in question
didn't exist.
The patch here fixes this by moving the capabilities checks out of the
LSM and into the caller. All (known) LSMs should have been calling the
capabilities hook already so it actually makes the code organization
better to eliminate the hook altogether.

Delete unused I2C adapter IDs. Special cases are:
* I2C_HW_B_RIVA was still set in driver rivafb, however no other
driver is ever looking for this value, so we can safely remove it.
* I2C_HW_B_HDPVR is used in staging driver lirc_zilog, however no
adapter ID is ever set to this value, so the code in question never
runs. As the code additionally expects that I2C_HW_B_HDPVR may not
be defined, we can delete it now and let the lirc_zilog driver
maintainer rewrite this piece of code.

The fix in commit 6b4e81db25 ("i8k: Tell gcc that *regs gets
clobbered") to work around the gcc miscompiling i8k.c to add "+m
(*regs)" caused register pressure problems and a build failure.
Changing the 'asm' statement to 'asm volatile' instead should prevent
that and works around the gcc bug as well, so we can remove the "+m".
[ Background on the gcc bug: a memory clobber fails to mark the function
the asm resides in as non-pure (aka "__attribute__((const))"), so if
the function does nothing else that triggers the non-pure logic, gcc
will think that that function has no side effects at all. As a result,
callers will be mis-compiled.
Adding the "+m" made gcc see that it's not a pure function, and so
does "asm volatile". The problem was never really the need to mark
"*regs" as changed, since the memory clobber did that part - the
problem was just a bug in the gcc "pure" function analysis - Linus ]

When asked to clear the intrusion alarm, do so immediately. We have to

We can't read the intrusion state from the real-time alarm registers
as we do for all other alarm flags, because real-time alarm bits don't
stick (by definition) and the intrusion state has to stick until
explicitly cleared (otherwise it has little value.)
So we have to use the interrupt status register instead, which is read
from the same address but with a configuration bit flipped in another
register.

This area of the code has always been a bit delicate due to the
subtleties of lock ordering. The problem is that for "normal"
alloc/dealloc, we always grab the inode locks first and the rgrp lock
later.
In order to ensure no races in looking up the unlinked, but still
allocated inodes, we need to hold the rgrp lock when we do the lookup,
which means that we can't take the inode glock.
The solution is to borrow the technique already used by NFS to solve
what is essentially the same problem (given an inode number, look up
the inode carefully, checking that it really is in the expected
state).
We cannot do that directly from the allocation code (lock ordering
again) so we give the job to the pre-existing delete workqueue and
carry on with the allocation as normal.
If we find there is no space, we do a journal flush (required anyway
if space from a deallocation is to be released) which should block
against the pending deallocations, so we should always get the space
back.
