kbuild: Fix genksyms handling of DEFINE_PER_CPU(struct foo_s *, bar);
This is a one-line change to parse.y.
To take advantage of this the scripts/genksyms/*_shipped files needs to
be rebuild - this is the next patch.
When a .c file contains:
DEFINE_PER_CPU(struct foo_s *, bar);
the .cpp output looks like:
__attribute__((__section__(".data.percpu"))) __typeof__(struct foo_s *) per_cpu__bar;
With the existing parse.y, the value inside the paranthesis of
__typeof__() does not evaluate as a type_specifier and therefore
per_cpu__bar does not get assigned a type for genksyms which results in
the EXPORT_PER_CPU_SYMBOL() not generating a CRC value.
I have compared the Modules.symvers with and without this
patch and for ia64's defconfig, the only change is:
Before 0x00000000 per_cpu____sn_nodepda vmlinux
After 0x9d3f3faa per_cpu____sn_nodepda vmlinux
per_cpu____sn_nodepda was the original source of my problems.

kbuild: set correct KBUILD_MODNAME when using well known kernel symbols as module names
This patch fixes a problem when we use well known kernel symbols as module
names.
For example, if module source name is current.c, idle_stack.c or etc.,
we have a bad KBUILD_MODNAME value.
For example, KBUILD_MODNAME will be "get_current()" instead of "current", or
"(init_thread_union.stack)" instead of "idle_task".
The trick is to define a stringify macro on the commandline - named
KBUILD_STR for namespace reasons - and then to stringify the module
name.
There are a few uses of KBUILD_MODNAME throughout the tree but the usage
is for debug and will not be harmed by this change so left untouched for now.
While at it KBUILD_BASENAME was changed too. Any spinlock usage in the
unix module would have created wrong section names without it.
Usage in spinlock.h fixed so it no longer stringify KBUILD_BASENAME.

[PATCH] md: fix is_mddev_idle calculation now that disk/sector accounting happens when request completes
md needs to monitor the rate of requests to its devices when doing
resync/recovery so that it can back-off when there is non-resync IO. It
does this by comparing resync IO, which it counts, with total IO which is
taken from disk_stats.
disk_stats were recently changed to account sectors when a request
completes instead of when it is queued. This upsets md's calculations.
We could do the sync_io accounting at the end of requests too, but that has
problems. If an underlying device is an md array, the accounting will
still be done when the request is submitted. This could be changed for
some raid levels, but it cannot be changed for raid0 or linear without
substantial code changes.
So instead, we increase the error that is_mddev_idle allows, up to the
maximum amount of resync IO that can be in flight at any time. The
calculation is current fragile as each personality as different limits for
in-flight resync. This should be fixed up.
For now, this simple patch fixes the problem.
Increasing the error margin decreases the sensitivity to non-resync IO. To
partially compensate for this, the time to wait when non-resync IO is
detected is increased so that less steady IO is required to keep the resync
at bay.
