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.

a95ca3b2b9 Blackfin arch: let PCI depend on BROKEN
AFAIR there exists blackfin hardware with PCI support, but the support
currently in the kernel fails to build starting with:

...
  CC      drivers/pci/probe.o
probe.c: In function 'pci_scan_slot':
probe.c:1056: error: implicit declaration of function 'pcibios_scan_all_fns'

a2e9c44337 blackfin: use generic show_mem()
Remove arch-specific show_mem() in favor of the generic version.

This also removes the following redundant information display:

	- free pages, printed by show_free_areas()
	- pages in swapcache, printed by show_swap_cache_info()

where show_mem() calls show_free_areas(), which calls
show_swap_cache_info().
