| 2011-12-08 | memblock: Fix include breakages caused by 24aa07882b | Tejun Heo | |
| 24aa07882b (memblock, x86: Replace memblock_x86_reserve/free_range() with generic ones) removed arch/x86/include/asm/memblock.h and dropped its inclusion from include/linux/memblock.h which breaks other architectures which depended on the generic memblock.h pulling in the arch specific one. However, the proper fix isn't adding back the asm inclusion. memblock doesn't have any arch dependent part and doesn't need arch specific header file and asm/memblock.h files are either practically empty or contain mostly unrelated arch specific stuff. * In microblaze, sh, powerpc, sparc and openrisc, asm/memblock.h is either empty or just contains unused MEMBLOCK_DBG() macro. Remove them. * In arm and unicore32, asm/memblock.h contains arch specific stuff. Include it directly from its users. It might be a good idea to rename the header file to avoid confusion.

| 2010-08-05 | memblock: Introduce default allocation limit and use it to replace explicit ones | Benjamin Herrenschmidt | |
| This introduce memblock.current_limit which is used to limit allocations from memblock_alloc() or memblock_alloc_base(..., MEMBLOCK_ALLOC_ACCESSIBLE). The old MEMBLOCK_ALLOC_ANYWHERE changes value from 0 to ~(u64)0 and can still be used with memblock_alloc_base() to allocate really anywhere. It is -no-longer- cropped to MEMBLOCK_REAL_LIMIT which disappears. Note to archs: I'm leaving the default limit to MEMBLOCK_ALLOC_ANYWHERE. I strongly recommend that you ensure that you set an appropriate limit during boot in order to guarantee that an memblock_alloc() at any time results in something that is accessible with a simple __va(). The reason is that a subsequent patch will introduce the ability for the array to resize itself by reallocating itself. The MEMBLOCK core will honor the current limit when performing those allocations. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> | |||
| 2010-07-14 | lmb: rename to memblock | Yinghai Lu | |
| via following scripts FILES=$(find * -type f | grep -vE 'oprofile|[^K]config') sed -i \ -e 's/lmb/memblock/g' \ -e 's/LMB/MEMBLOCK/g' \ $FILES for N in $(find . -name lmb.[ch]); do M=$(echo $N | sed 's/lmb/memblock/g') mv $N $M done and remove some wrong change like lmbench and dlmb etc. also move memblock.c from lib/ to mm/ Suggested-by: Ingo Molnar <mingo@elte.hu> Acked-by: "H.
