edac: sb_edac.c should not require prescence of IMC_DDRIO device

The Sandy Bridge EDAC driver uses a register in the IMC_DDRIO CSR
space to determine the type of DIMMs (registered or unregistered).
But this device does not exist on some single socket Sandy Bridge
servers.  While the type of DIMMs is nice to know, it is not essential
for this driver's other functions. So it seems harsh to have it
refuse to load at all when it cannot find this device.

Make the check for this device be optional. If it isn't present
just report the memory type as "MEM_UNKNOWN".

ARM: tegra: call cpu_do_idle from C code

When building a kernel for multiple CPU architecture levels,
cpu_do_idle() is a macro for an indirect function call, which
cannot be called from assembly code as Tegra does.

Adding a trivial C wrapper for this function lets us build
a tegra kernel with ARMv6 support enabled.

Turn off -Wmaybe-uninitialized when building with -Os

gcc-4.7 and higher add a lot of false positive warnings about
potential uses of uninitialized warnings, but only when optimizing
for size (-Os). This is the default when building allyesconfig,
which turns on CONFIG_CC_OPTIMIZE_FOR_SIZE.

In order to avoid getting a lot of patches that initialize such
variables and accidentally hide real errors along the way, let's
just turn off this warning on the respective gcc versions
when building with size optimizations. The -Wmaybe-uninitialized
option was introduced in the same gcc version (4.7) that is now
causing the false positives, so there is no effect on older compilers.

A side effect is that when building with CONFIG_CC_OPTIMIZE_FOR_SIZE,
we might now see /fewer/ warnings about possibly uninitialized
warnings than with -O2, but that is still much better than seeing
warnings known to be bogus.

NFSv4: Servers should only check SETATTR stateid open mode on size change

The NFSv4 and NFSv4.1 specs are both clear that the server should only check
stateid open mode if a SETATTR specifies the size attribute. If the
open mode is not one that allows writing, then it returns NFS4ERR_OPENMODE.

In the case where the SETATTR is not changing the size, the client will
still pass it the delegation stateid to ensure that the server does not
recall that delegation. In that case, the server should _ignore_ the
delegation open mode, and simply apply standard permission checks.
