Since memblock API is widely used by other architectures this feature can be enabled outside of x86 world. This patch set promotes memtest to live under generic mm umbrella and enabl= es memtest feature for arm/arm64. It was reported that this patch set was useful for tracking down an issue w= ith some errant DMA on an arm64 platform. Since it touches x86 and mm bits it'd be great to get ACK/NAK for these bit= s. Changelog: RFC -> v1 - updated kernel-parameters.txt for memtest entry - updated number of test patterns in Kconfig menu - added Acked/Tested tags for arm64 bits - rebased on v4.0-rc3 Vladimir Murzin (6): mm: move memtest under /mm memtest: use phys_addr_t for physical addresses arm64: add support for memtest arm: add support for memtest Kconfig: memtest: update number of test patterns up to 17 Documentation: update arch list in the 'memtest' entry Documentation/kernel-parameters.txt | 2 +- arch/arm/mm/init.c | 3 + arch/arm64/mm/init.c | 2 + arch/x86/Kconfig | 11 ---- arch/x86/include/asm/e820.h | 8 --- arch/x86/mm/Makefile | 2 - arch/x86/mm/memtest.c | 118 -------------------------------= ---- include/linux/memblock.h | 8 +++ lib/Kconfig.debug | 11 ++++ mm/Makefile | 1 + mm/memtest.c | 118 +++++++++++++++++++++++++++++++= ++++ 11 files changed, 144 insertions(+), 140 deletions(-) delete mode 100644 arch/x86/mm/memtest.c create mode 100644 mm/memtest.c --=20 1.7.9.5 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
