X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=103340cc36384c1afee4453b65a784d8b20d9d8d;p=linux-beck.git sh: Fix up unaligned current_text_addr(). As noted by Adrian: Commit 3ab83521378268044a448113c6aa9a9e245f4d2f (kexec jump) causes the following build error on sh: <-- snip --> ... CC kernel/kexec.o {standard input}: Assembler messages: {standard input}:1518: Error: offset to unaligned destination make[2]: *** [kernel/kexec.o] Error 1 <-- snip --> If I understand the assembler correctly it fails at include/asm-sh/kexec.h:59 The issue here is that the mova reference lacks an explicit alignment, and previous code paths would end up with this on a 16-bit boundary, so we make the alignment explicit.
