[PATCH] FRV: Make the FRV arch work again
The attached patch implements a bunch of small changes to the FRV arch to
make it work again.
It deals with the following problems:
(1) SEM_DEBUG should be SEMAPHORE_DEBUG.
(2) The argument list to pcibios_penalize_isa_irq() has changed.
(3) CONFIG_HIGHMEM can't be used directly in #if as it may not be defined.
(4) page->private is no longer directly accessible.
(5) linux/hardirq.h assumes asm/hardirq.h will include linux/irq.h
(6) The IDE MMIO access functions are given pointers, not integers, and so
get type casting errors.
(7) __pa() is passed an explicit u64 type in drivers/char/mem.c, but that
can't be cast directly to a pointer on a 32-bit platform.
(8) SEMAPHORE_DEBUG should not be contingent on WAITQUEUE_DEBUG as that no
longer exists.
(9) PREEMPT_ACTIVE is too low a value.
