[RFC PATCH 1/2] log2: handle LARGE input to __roundup_pow_of_two()

en the MSbit is 32 or 64, we cannot roundup to the next power of 2, so just return n (the input value), which is >= 0x8000... and probably not a power of 2 (unless it is exactly 0x8000...). Signed-off-by: Randy Dunlap Cc: Jens Axboe Cc: Andrew Morton Cc: Toralf Förster Cc: li

[PATCH] zlib: move EXPORT_SYMBOL() and MODULE_LICENSE() out of dfltcc_syms.c

ORT_SYMBOL() immediately after the function that it applies to, so move all EXPORT_SYMBOL()s to their respective function locations and drop the dfltcc_syms.c file. Also move MODULE_LICENSE() from the deleted file to dfltcc.c. Fixes: 11fb479ff5d9 ("zlib: export S390 symbols for zlib modules")
