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.

There is no machine class overriding this. If non linear translations are implemented again for some machines then this could be restored at that time. Signed-off-by: NNicolas Pitre <nico@marvell.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

The restriction on !CONFIG_HIGHMEM is unneeded since page tables are currently never allocated with highmem pages, and actually disable PTE dump whenever highmem is configured. Let's have a dynamic test to better describe the current limitation instead. Signed-off-by: NNicolas Pitre <nico@marvell.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Make free_area() arguments pfn based, and return number of freed pages. This will simplify highmem initialization later. Also, codepages, datapages and initpages are actually codesize, datasize and initsize. Signed-off-by: NNicolas Pitre <nico@marvell.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Doing so will greatly simplify the bootmem initialization code as each bank is therefore entirely lowmem or highmem with no crossing between those zones. Signed-off-by: NNicolas Pitre <nico@marvell.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

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. Also fix a few conversion errors in copypage-feroceon.c and copypage-v4mc.c. Signed-off-by: NNicolas Pitre <nico@marvell.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

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>

People often point to the Integrator/Versatile/Realview implementations to justify using the consumer name as the sole selector for clocks.

As suggested by Andrew Morton, remove memzero() - it's not supported on other architectures so use of it is a potential build breaking bug. Since the compiler optimizes memset(x,0,n) to __memzero() perfectly well, we don't miss out on the underlying benefits of memzero(). Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

The G3IPL expects the value at RAM address 0xa020b020 to be exactly 1 to setup the bluetooth GPIOs properly.

Mikael Pettersson reported: The 2.6.28-rc kernels fail to detect PCI device 0000:00:01.0 (the first ethernet port) on my Thecus n2100 XScale box. There is however still a strange "ghost" device that gets partially detected in 2.6.28-rc2 vanilla. The IOP321 manual says: The user designates the memory region containing the OCCDR as non-cacheable and non-bufferable from the IntelR XScaleTM core. This guarantees that all load/stores to the OCCDR are only of DWORD quantities. Ensure that the OCCDR is so mapped. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>
