From 66a5c40f60f5d88ad8d47ba6a4ba05892853fa1f Mon Sep 17 00:00:00 2001 From: Tanzir Hasan Date: Tue, 26 Dec 2023 18:00:00 +0000 Subject: 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.
