From 51b26ada79b605ed709ddcedbb6012e8f8e0ebed Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 26 Apr 2009 10:12:47 -0700 Subject: x86: unify arch/x86/boot/compressed/vmlinux_*.lds Look at the: diff -u arch/x86/boot/compressed/vmlinux_*.lds output and realize that they're basially exactly the same except for trivial naming differences, and the fact that the 64-bit version has a "pgtable" thing. So unify them. There's some trivial cleanup there (make the output format a Kconfig thing rather than doing #ifdef's for it, and unify both 32-bit and 64-bit BSS end to "_ebss", where 32-bit used to use the traditional "_end"), but other than that it's really very mindless and straigt conversion. For example, I think we should aim to remove "startup_32" vs "startup_64", and just call it "startup", and get rid of one more difference. I didn't do that. Also, notice the comment in the unified vmlinux.lds.S talks about "head_64" and "startup_32" which is an odd and incorrect mix, but that was actually what the old 64-bit only lds file had, so the confusion isn't new, and now that mixing is arguably more accurate thanks to the vmlinux.lds.S file being shared between the two cases ;) [ Impact: cleanup, unification ] Signed-off-by: Linus Torvalds Acked-by: Sam Ravnborg Signed-off-by: Ingo Molnar --- arch/x86/boot/compressed/head_32.S | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'arch/x86/boot/compressed/head_32.S') diff --git a/arch/x86/boot/compressed/head_32.S b/arch/x86/boot/compressed/head_32.S index 3a8a866fb2e..85bd3285706 100644 --- a/arch/x86/boot/compressed/head_32.S +++ b/arch/x86/boot/compressed/head_32.S @@ -88,9 +88,9 @@ ENTRY(startup_32) * where decompression in place becomes safe. */ pushl %esi - leal _end(%ebp), %esi - leal _end(%ebx), %edi - movl $(_end - startup_32), %ecx + leal _ebss(%ebp), %esi + leal _ebss(%ebx), %edi + movl $(_ebss - startup_32), %ecx std rep movsb @@ -121,7 +121,7 @@ relocated: */ xorl %eax,%eax leal _edata(%ebx),%edi - leal _end(%ebx), %ecx + leal _ebss(%ebx), %ecx subl %edi,%ecx cld rep -- cgit v1.2.3
