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.
