Andy Shevchenko	9f2c2d6ba1	bitops: Move aligned_byte_mask() to wordpart.h ... The bitops.h is for bit related operations. The aligned_byte_mask() is about byte (or part of the machine word) operations, for which we have a separate header, move the mentioned macro to wordpart.h to consolidate similar operations.

Andy Shevchenko	adeb04362d	kernel.h: Move upper_*_bits() and lower_*_bits() to wordpart.h ... The wordpart.h header is collecting APIs related to the handling parts of the word (usually in byte granularity). The upper_*_bits() and lower_*_bits() are good candidates to be moved to there. This helps to clean up header dependency hell with regard to kernel.h as the latter gathers completely unrelated stuff together and slows down compilation (especially when it's included into other header).

Tanzir Hasan	66a5c40f60	kernel.h: removed REPEAT_BYTE from kernel.h ... This patch creates wordpart.h and includes it in asm/word-at-a-time.h for all architectures. WORD_AT_A_TIME_CONSTANTS depends on kernel.h because of REPEAT_BYTE. Moving this to another header and including it where necessary allows us to not include the bloated kernel.h. Making this implicit dependency on REPEAT_BYTE explicit allows for later improvements in the lib/string.c inclusion list.
