+ help
+ How should we handle alignment errors in userspace by default? This is a bitfield where:
+ 0 - silently ignore alignment errors (will lead to unexpected results)
+ 1 - report alignment errors through printk (will lead to unexpected results, but you'll know about them)
+ 2 - fix the alignment and make things work properly (performance degradation for un-aligned code)
+ 4 - raise SIGBUS on alignment traps
+ A good number to choose is probably either 3 (work slowly but log message) or 5 (log message and SIGBUS).
+ You can change the behavior at runtime through /proc/cpu/alignment if you have PROC_FS enabled.

Subject: [PATCH] pxa: define smsc911x structures for pcmcia too
The gumstix pcmcia support (which the wireless driver uses) needs
to know about the smsc911x platform device even if smsc811x support
is disabled, as they share resources.

Subject: [PATCH] [ARM] pxa: fix Verdex Pro mmc initialization
The MicroSD port doesn't have card detect, read-only switch
support, and is continuously powered. Somewhere in the
forward-porting this got lost in the structure initialization.
