treewide: Add SPDX license identifier for more missed files

2019-05-21T08:50:45+00:00

Add SPDX license identifiers to all files which: - Have no license information of any form - Have MODULE_LICENCE("GPL*") inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

ARM: 8187/1: add CONFIG_HAVE_ARCH_BITREVERSE to support rbit instruction

2014-12-22T16:43:06+00:00

this change add CONFIG_HAVE_ARCH_BITREVERSE config option, so that we can use some architecture's bitrev hardware instruction to do bitrev operation. Introduce __constant_bitrev* macro for constant bitrev operation. Change __bitrev16() __bitrev32() to be inline function, don't need export symbol for these tiny functions.

[PATCH] add MODULE_* attributes to bit reversal library

2006-12-10T18:07:52+00:00

Add MODULE_* attributes to the new bit reversal library. Most notably MODULE_LICENSE which prevents superfluous kernel tainting. Signed-off-by: Cal Peake Signed-off-by: Linus Torvalds

[PATCH] bit reverse library

2006-12-08T16:28:39+00:00

This patch provides two bit reverse functions and bit reverse table. - reverse the order of bits in a u32 value u8 bitrev8(u8 x); - reverse the order of bits in a u32 value u32 bitrev32(u32 x); - byte reverse table const u8 byte_rev_table[256]; Signed-off-by: Akinobu Mita Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
