This is because arch_ffz() ends up invoking the 32-bit version of __ilog2()
which always returns a bit number in the range 0 - 31. This can cause
"overlap" variable in axmap_set_fn() to never becomes zero.

To fix this the commit adds a 64-bit version of __ilog2() (obtained from the
Linux kernel's arch/powerpc/include/asm/bitops.h).

Tomohiro Kusumi [Mon, 8 Jun 2015 10:19:02 +0000 (19:19 +0900)]
Clear sysfs path before reading current ioscheduler from sysfs

switch_ioscheduler() function has a local buffer tmp[] to store
both sysfs path (e.g. /sys/block/`device`/queue/scheduler) and
content of that sysfs path.

In order to properly test strstr() after writing a ioscheduler
string (e.g. "deadline") to sysfs, it needs to memset(0) first.
Otherwise if the content of sysfs path (below (b)) is shorter
than the existing sysfs path in tmp[] (below (a)), then tmp[]
after storing the content of sysfs (below (c) and *haystack of
strstr()) contains remaining part of the sysfs path.

(a) "/sys/block/sdb/queue/scheduler"
(b) "noop [deadline] cfq \n"
(c) "noop [deadline] cfq \nscheduler"

strstr() will result the same given that the remaining part of
the sysfs path is unlikely to contain ioscheduler string, but
the remaining part should still be cleared first.
