Add support for the sh7372 INTCS interrupt controller.
INTCS is the interrupt controller for the sh7372 SuperH

controller which interfaces to the ARM processor.
INTCS support is implemented using a new INTC table
together with a chained interrupt handler that ties
into the already supported INTCA controller.

ARM: mach-shmobile: Use 0x2200 as INTCS_VECT_BASE
Change INTCS_VECT_BASE from 0x3400 to 0x2200.
The old value 0x3400 gave the INTCA and INTCS interrupt
conrollers separated spaces, but required ARM support
for more than 512 NR_IRQS which is not in place at this
point.
The value 0x2200 will make some of the INTCA interrupts
make use of empty INTCS areas. This is a bit more error
prone but works fine as a workaround for G3, G3 and AP4.

cpumask: fix compat getaffinity
Commit a45185d2d "cpumask: convert kernel/compat.c" broke libnuma, which
abuses sched_getaffinity to find out NR_CPUS in order to parse
/sys/devices/system/node/node*/cpumap.
On NUMA systems with less than 32 possibly CPUs, the current
compat_sys_sched_getaffinity now returns '4' instead of the actual
NR_CPUS/8, which makes libnuma bail out when parsing the cpumap.
The libnuma call sched_getaffinity(0, bitmap, 4096) at first. It mean
the libnuma expect the return value of sched_getaffinity() is either len
argument or NR_CPUS. But it doesn't expect to return nr_cpu_ids.
Strictly speaking, userland requirement are
1) Glibc assume the return value mean the lengh of initialized
of mask argument. E.g. if sched_getaffinity(1024) return 128,
glibc make zero fill rest 896 byte.
2) Libnuma assume the return value can be used to guess NR_CPUS
in kernel. It assume len-arg<NR_CPUS makes -EINVAL. But
it try len=4096 at first and 4096 is always bigger than
NR_CPUS. Then, if we remove strange min_length normalization,
we never hit -EINVAL case.
sched_getaffinity() already solved this issue. This patch adapts
compat_sys_sched_getaffinity() to match the non-compat case.

nfsd: safer initialization order in find_file()
The alloc_init_file() first adds a file to the hash and then
initializes its fi_inode, fi_id and fi_had_conflict.
The uninitialized fi_inode could thus be erroneously checked by
the find_file(), so move the hash insertion lower.
The client_mutex should prevent this race in practice; however, we
eventually hope to make less use of the client_mutex, so the ordering
here is an accident waiting to happen.
I didn't find whether the same can be true for two other fields,
but the common sense tells me it's better to initialize an object
before putting it into a global hash table :)

nfs4: minor callback code simplification, comment
Note the position in the version array doesn't have to match the actual
rpc version number--to me it seems clearer to maintain the distinction.
Also document choice of rpc callback version number, as discussed in
e.g. http://www.ietf.org/mail-archive/web/nfsv4/current/msg07985.html
and followups.
