[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.
