i2c: Fix device name for 10-bit slave address
10-bit addresses overlap with traditional 7-bit addresses, leading in
device name collisions. Add an arbitrary offset to 10-bit addresses to
prevent this collision. The offset was chosen so that the address is
still easily recognizable.

bnx2x: cache-in compressed fw image
Re-request fw from fs may fail for different reasons, once the fw was
loaded we won't release it until driver is removed.
This also resolves the boot problem when initial fw is located on initrd,
but rootfs is still unavailable, in this case device reset will fail due
to absence of fw files.

pstore: pass allocated memory region back to caller
The buf_lock cannot be held while populating the inodes, so make the backend
pass forward an allocated and filled buffer instead. This solves the following
backtrace. The effect is that "buf" is only ever used to notify the backends
that something was written to it, and shouldn't be used in the read path.
To replace the buf_lock during the read path, isolate the open/read/close
loop with a separate mutex to maintain serialized access to the backend.
Note that is is up to the pstore backend to cope if the (*write)() path is
called in the middle of the read path.

This allows a backend to filter on the dmesg reason as well as the pstore

has no obviously correct value.
