2011-01-03ARM: pxa: fix page table corruption on resumeAric D. Blumer
Before this patch, the following error would sometimes occur after a resume on pxa3xx: /path/to/mm/memory.c:144: bad pmd 8040542e. The problem was that a temporary page table mapping was being improperly restored. The PXA3xx resume code creates a temporary mapping of resume_turn_on_mmu to avoid a prefetch abort. The pxa3xx_resume_after_mmu code requires that the r1 register holding the address of this mapping not be modified, however, resume_turn_on_mmu does modify it. It is mostly correct in that r1 receives the base table address, but it may also get other bits in 13:0. This results in pxa3xx_resume_after_mmu restoring the original mapping to the wrong place, corrupting memory and leaving the temporary mapping in place.

Replace the page_to_dma() and dma_to_page() macros with their PFN equivalents. This allows us to map parts of memory which do not have a struct page allocated to them to bus addresses. This will be used internally by dma_alloc_coherent()/dma_alloc_writecombine(). Build tested on Versatile, OMAP1, IOP13xx and KS8695.

2010-12-24ARM: 6532/1: Allow machine to specify it's own IRQ handlers at run-timeeric miao
Normally different ARM platform has different way to decode the IRQ hardware status and demultiplex to the corresponding IRQ handler. This is highly optimized by macro irq_handler in entry-armv.S, and each machine defines their own macro to decode the IRQ number. However, this prevents multiple machine classes to be built into a single kernel. By allowing each machine to specify thier own handler, and making function pointer 'handle_arch_irq' to point to it at run time, this can be solved. And introduce CONFIG_MULTI_IRQ_HANDLER to allow both solutions to work. Comparing with the highly optimized macro of irq_handler, the new function must be written with care not to lose too much performance. And the IPI stuff on SMP is expected to move to the provided arch IRQ handler as well. The assembly code to invoke handle_arch_irq is optimized by Russell King.
