ARM: mm: fix boot on SA1110 Assabet

2013-07-22T01:21:35Z

commit 319e0b4f02f73983c03a2ca38595fc6367929edf upstream. Commit 83db0384 (mm/ARM: use common help functions to free reserved pages) broke booting on the Assabet by trying to convert a PFN to a virtual address using the __va() macro. This macro takes the physical address, not a PFN. Fix this. Signed-off-by: Russell King Signed-off-by: Greg Kroah-Hartman

mm, show_mem: suppress page counts in non-blockable contexts

2013-04-29T22:54:28Z

On large systems with a lot of memory, walking all RAM to determine page types may take a half second or even more. In non-blockable contexts, the page allocator will emit a page allocation failure warning unless __GFP_NOWARN is specified. In such contexts, irqs are typically disabled and such a lengthy delay may even result in NMI watchdog timeouts. To fix this, suppress the page walk in such contexts when printing the page allocation failure warning.

ARM: Allow arm_memblock_steal() to remove memory from any RAM region

2012-08-12T23:22:28Z

Allow arm_memblock_steal() to remove memory from any RAM region, including highmem areas. This allows memory to be stolen from the very top of declared memory, including highmem areas, rather than our precious lowmem. Acked-by: Sascha Hauer Acked-by: Santosh Shilimkar Signed-off-by: Russell King

ARM: mm: fix type of the arm_dma_limit global variable

2012-06-11T12:30:47Z

arm_dma_limit stores physical address of maximal address accessible by DMA, so the phys_addr_t type makes much more sense for it instead of u32. This patch fixes the following build warning: arch/arm/mm/init.c:380: warning: comparison of distinct pointer types lacks a cast Reported-by: Russell King Signed-off-by: Marek Szyprowski

ARM: integrate CMA with DMA-mapping subsystem

2012-05-21T13:09:38Z

This patch adds support for CMA to dma-mapping subsystem for ARM architecture. By default a global CMA area is used, but specific devices are allowed to have their private memory areas if required (they can be created with dma_declare_contiguous() function during board initialisation). Contiguous memory areas reserved for DMA are remapped with 2-level page tables on boot. Once a buffer is requested, a low memory kernel mapping is updated to to match requested memory access type. GFP_ATOMIC allocations are performed from special pool which is created early during boot. This way remapping page attributes is not needed on allocation time. CMA has been enabled unconditionally for ARMv6+ systems.

ARM: 7401/1: mm: Fix section mismatches
