5e95320f9f Blackfin arch: rename blackfin_sram.c to sram-alloc.c 
rename blackfin_sram.c to sram-alloc.c (we know it is a blackfin file,
since it is in arch/blackfin) - and there is no "driver" code in there,
it is just an allocator/deallocator for L1 and L2 sram.

Also fix a problem that checkpatch pointed out

226a6ec311 Blackfin arch: sram: use 'unsigned long' for irqflags 
Using just 'unsigned' will make flags an unsigned int. While this is
arguably not an error on blackfin where sizeof(int) == sizeof(long),
the patch is still justified on the grounds of principle.

The patch was generated using the Coccinelle semantic patch framework.
