The new MUSB power code needs musb_read_txhubport() to return a value (so
stub it as 0 like the other Blackfin hub funcs). It also needs new helper
functions for saving/restoring context, so change the apparently unused
musb_platform_{suspend,resume} to musb_platform_{save,rest

Some drivers allocate L1 SRAM in atomic contexts, so make sure these
functions also use GFP_ATOMIC to avoid BUG()'s.

A few pseudo debug insns exist to make testing of simulators easier.
Since these don't actually exist in the hardware, we have to have the
exception handler take care of emulating these. This allows sim test
cases to be executed unmodified under Linux and thus simplify debugging

The timeout value is in jiffies, so it should be using HZ, not a plain

The IADDR2DTEST() macro had some duplicated logic with bit 11 and some
incorrect comments, so scrub all of that.
In order to verify these aren't a problem (and won't be in the future),
extend the self tests to operate on as much L1 SRAM as possible.

Add a little strncpy optimization which can easily cut boot time by 20%.
When the kernel is booting with initramfs, it builds up the filesystem
from a cpio archive by calling strncpy_from_user() via fs/namei.c's
do_getname() on every file in the archive (which can be lots) with

Now that the split traps code has moved all the verbose output to the
