linux-toradex.git/arch/sh/kernel/head_64.S, branch v4.19 Linux kernel for Apalis and Colibri modules mm, arch: remove empty_bad_page* 2017-11-16T02:21:03+00:00 Michal Hocko mhocko@suse.com 2017-11-16T01:34:22+00:00 8745808fda84c638e45cc860c8fb600bf4b0a2a6 empty_bad_page() and empty_bad_pte_table() seem to be relics from old days which is not used by any code for a long time. I have tried to find when exactly but this is not really all that straightforward due to many code movements - traces disappear around 2.4 times. Anyway no code really references neither empty_bad_page nor empty_bad_pte_table. We only allocate the storage which is not used by anybody so remove them.

sh64: Fix up early serial fixmap. 2010-01-12T06:22:26+00:00 Paul Mundt lethal@linux-sh.org 2010-01-12T06:22:26+00:00 65fedbbef8404be5e1dbd18bdad252616b49a24b This was conditionalized on CONFIG_EARLY_PRINTK, which has subsequently gone away. Now that the serial driver always supports the early console, make sure we always establish the mapping. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh: convert to use __HEAD and HEAD_TEXT macros. 2009-04-26T16:20:39+00:00 Tim Abbott tabbott@MIT.EDU 2009-04-26T02:11:07+00:00 bbe215c231ac809e42b037345c1fa8e8eb09b00a This has the consequence of changing the section name use for head code from ".text.head" to ".head.text". Since this commit changes all users in the architecture, this change should be harmless.
