While testing various randconfigs with ktest.pl, I hit the following panic:

BUG: unable to handle kernel paging request at f7e54b03
IP: [<c0d63409>] ibmphp_access_ebda+0x101/0x19bb

Adding printks, I found that the loop that reads the ebda blocks
can move out of the mapped section.

ibmphp_access_ebda: start=f7e44c00 size=5120 end=f7e46000
ibmphp_access_ebda: io_mem=f7e44d80 offset=384
ibmphp_access_ebda: io_mem=f7e54b03 offset=65283

The start of the iomap was at f7e44c00 and had a size of 5120,
making the end f7e46000. We start with an offset of 0x180 or
384, giving the first read at 0xf7e44d80. Reading that location
yields 65283, which is much bigger than the 5120 that was allocated
and makes the next read at f7e54b03 which is outside the mapped area.

Perhaps this is a bug in the driver, or buggy hardware, but this patch
is more about not crashing my box on start up and just giving a warning
if it detects this error.

This patch at least lets my box boot with just a warning.

Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Sometimes it is possible and reasonable to adjust the parent clock rate to
improve precision of the child clock, e.g., if the child clock has no siblings.
clk_round_parent() is a new addition to the SH clock-framework API, that
implements such an optimization for child clocks with divisors, taking all
integer values in a range.

While scanning the floopy code due to c093ee4f ("floppy: fix
use-after-free in module load failure path"), I found one more instance
of trying to access disk->queue pointer after doing put_disk() on
gendisk.  For some reason , floppy moule still loads/unloads fine.  The
object is probably still around with right pointer values.

 o There seems to be one more instance of trying to cleanup the request
   queue after we have called put_disk() on associated gendisk.

 o This fix is more out of code inspection.  Even without this fix for
   some reason I am able to load/unload floppy module without any
   issues.

 o Floppy module loads/unloads fine after the fix.

Commit 27ae60f8 ("ipw2x00: replace "ieee80211" with "libipw" where
appropriate") changed DRV_NAME to be "libipw", but didn't properly fix
up the places where it was used to specify the name for the /proc/net/
directory.

For backwards compatibility reasons, that directory name remained
"ieee80211", but due to the DRV_NAME change, the error case printouts
and the cleanup functions now used "libipw" instead.  Which made it all
fail badly.

For example, on module unload as reported by Randy:

  WARNING: at fs/proc/generic.c:816 remove_proc_entry+0x156/0x35e()
  name 'libipw'

because it's trying to unregister a /proc directory that obviously
doesn't even exist.

Clean it all up to use DRV_PROCNAME for the actual /proc directory name.

adapter->id is deprecated and not set by any adapter driver, so this
was certainly not what the author wanted to use. adapter->nr maybe,
but as dev_err() already includes this value, as well as the client's
