Hi,
While testing MFC decoder on Exynos machines, I encountered some
memory allocation errors due to failure of dma_alloc_coherent().
File: drivers/media/platform/s5p-mfc/s5p_mfc_ctrl.c Line: 38.
Git bisect pointed me to the following commit as the first bad commit
(linux-next tree of 20130531):
commit 3d5272d9b289cd0930b2ea9984406d757a72f4dd

lib/bitmap.c: speed up bitmap_find_free_region
Reverting this (and the commit 197e1cf7
("ib-bitmapc-speed-up-bitmap_find_free_region-fix") ) fixes this
issue.
Looks like some regression has been introduced by the above patch?

With warm regards,
