[PATCH] radix-tree: fix radix_tree_prev_hole underflow case
radix_tree_prev_hole() used LONG_MAX to detect underflow; however, ULONG_MAX is clearly what was intended, both here and by its only user (count_history_pages at mm/readahead.c).

[PATCH 27/35] swiotlb: Use page alignment for early buffer allocation
for 2.6.34 We could call free_bootmem_late() if swiotlb is not used, and it will shrink to page alignement. So alloc them with page alignment at first, to avoid lose two pages before patch: [ 0.000000] lmb_reserve_area: [00d3600000, 00d7600000] swiotlb buffer [ 0.000000] lmb_reserve_area: [0... 13 May 2010 21:35

[PATCH 04/35] lmb: Add lmb_find_area()
it is a wrapper for lmb_find_base make it more easy for x86 to use lmb. ( rebase ) x86 early_res is using find/reserve pattern instead of alloc. -v2: Change name to lmb_find_area() according to Michael Ellerman -v3: Add generic weak version __lmb_find_area() so keep the path for fallback to x86 version th... 13 May 2010 21:35
