RiscPC is the only platform using the default setting for NR_IRQS, so the default NR_IRQS doesn't really make sense; remove it and make RiscPC provide such a definition. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This avoids confusion with platform specific DMA implementations in mach/dma.h Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

Since 8d5796d2, we have allowed PAGE_OFFSET to be configurable, so a constant virtual address for MAX_DMA_ADDRESS is buggy. It should be defined in terms of PAGE_OFFSET rather than a constant virtual address. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.

Currently there are two instances of struct meminfo: one in kernel/setup.c marked __initdata, and another in mm/init.c with permanent storage. Let's keep only the later to directly populate the permanent version from arm_add_memory(). Also move common validation tests between the MMU and non-MMU cases into arm_add_memory() to remove some duplication. Protection against overflowing the membank array is also moved in there in order to cover the kernel cmdline parsing path as well.

In all cases the kaddr is assigned an input register even though it is modified in the assembly code. Let's assign a new variable to the modified value and mark those inline asm with volatile otherwise they get optimized away because the output variable is otherwise not used.

For similar reasons as copy_user_page(), we want to avoid the additional kmap_atomic if it's unnecessary. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>
-
由 Russell King 提交于
We used to override the copy_user_page() function. However, this is not only inefficient, it also causes additional complexity for highmem support, since we convert from a struct page to a kernel direct mapped address and back to a struct page again. Moreover, with highmem support, we end up pointlessly setting up kmap entries for pages which we're going to remap. So, push the kmapping down into the copypage implementation files where it's required. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>
