Blackfin: Split the BF532 BFIN_*_FIO_FLAG() functions to their own header Split the BF532 machine type BFIN_*_FIO_FLAG() functions to their own header file to avoid circular #include problems as these functions require IRQ flag handling, which requires asm/blackfin.h, which otherwise requires the header file that defines these functions. For good measure, also get rid of the inclusion of asm/blackfin.h from mach/cdefBF532.h (which is circular) and defBF532.h (which is included by asm/blackfin.h before including this header).

Blackfin: Rename IRQ flags handling functions Rename h/w IRQ flags handling functions to be in line with what is expected for the irq renaming patch. This renames local_*_hw() to hard_local_*() using the following perl command: perl -pi -e 's/local_irq_(restore|enable|disable)_hw/hard_local_irq_\1/ or s/local_irq_save_hw([_a-z]*)[(]flags[)]/flags = hard_local_irq_save\1()/' `find arch/blackfin/ -name "*.[ch]"` and then fixing up asm/irqflags.h manually. Additionally, arch/hard_local_save_flags() and arch/hard_local_irq_save() both return the flags rather than passing it through the argument list. Signed-off-by: David Howells <dhowells@redhat.com>
