+Subject: [PATCH] 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.

+Subject: [PATCH] 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).
