idr: introduce idr_alloc_cyclic()
As Tejun points out, there are several users of the IDR facility that
attempt to use it in a cyclic fashion. These users are likely to see
-ENOSPC errors after the counter wraps one or more times however.
This patchset adds a new idr_alloc_cyclic routine and converts several
of these users to it. Many of these users are in obscure parts of the
kernel, and I don't have a good way to test some of them. The change is
pretty straightforward though, so hopefully it won't be an issue.
There is one other cyclic user of idr_alloc that I didn't touch in
ipc/util.c. That one is doing some strange stuff that I didn't quite
understand, but it looks like it should probably be converted later
somehow.
This patch:
Thus spake Tejun Heo:
Ooh, BTW, the cyclic allocation is broken. It's prone to -ENOSPC
after the first wraparound. There are several cyclic users in the
kernel and I think it probably would be best to implement cyclic
support in idr.
This patch does that by adding new idr_alloc_cyclic function that such
users in the kernel can use. With this, there's no need for a caller to
keep track of the last value used as that's now tracked internally. This
should prevent the ENOSPC problems that can hit when the "last allocated"
counter exceeds INT_MAX.
Later patches will convert existing cyclic users to the new interface.

fat (exportfs): rebuild directory-inode if fat_dget()
This patch enables rebuilding of directory inodes which are not present in
the cache.This is done by traversing the disk clusters to find the
directory entry of the parent directory and using its i_pos to build the
inode.
The traversal is done by fat_scan_logstart() which is similar to
fat_scan() but matches i_pos values instead of names.fat_scan_logstart()
needs an inode parameter to work, for which a dummy inode is created by
it's caller fat_rebuild_parent(). This dummy inode is destroyed after the
traversal completes.
All this is done only if the nostale_ro nfs mount option is specified.

drivers/rtc/rtc-cmos.c: don't disable hpet emulation on suspend
There's a bug where rtc alarms are ignored after the rtc cmos suspends
but before the system finishes suspend. Since hpet emulation is
disabled and it still handles the interrupts, a wake event is never
registered which is done from the rtc layer.
This patch reverts commit
d1b2efa83fbf ("rtc: disable hpet emulation on
suspend") which disabled hpet emulation. To fix the problem mentioned
in that commit, hpet_rtc_timer_init() is called directly on resume.

drivers/rtc/rtc-tps65910.c: fix incorrect return value on error
'ret' was not initialized to correct error value before returning.
Since 'irq' is also being tested for 0, we cannot return irq itself as
it means function is success even though we are returning before
completing the probe.

drivers/rtc/rtc-tps6586x.c: remove incorrect use of rtc_device_unregister
Device managed functions do not need explicit freeing/unregistering.
Moreover in this case it was done using non-device managed function
which is incorrect. Hence remove it.
