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/vmlinux.lds.S | 57 ++++++++++++++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 arch/x86/boot/compressed/vmlinux.lds.S (limited to 'arch/x86/boot/compressed/vmlinux.lds.S') diff --git a/arch/x86/boot/compressed/vmlinux.lds.S b/arch/x86/boot/compressed/vmlinux.lds.S new file mode 100644 index 0000000..ffcb191 --- /dev/null +++ b/arch/x86/boot/compressed/vmlinux.lds.S @@ -0,0 +1,57 @@ +OUTPUT_FORMAT(CONFIG_OUTPUT_FORMAT, CONFIG_OUTPUT_FORMAT, CONFIG_OUTPUT_FORMAT) + +#ifdef CONFIG_X86_64 +OUTPUT_ARCH(i386:x86-64) +ENTRY(startup_64) +#else +OUTPUT_ARCH(i386) +ENTRY(startup_32) +#endif + +SECTIONS +{ + /* Be careful parts of head_64.S assume startup_32 is at + * address 0. + */ + . = 0; + .text.head : { + _head = . ; + *(.text.head) + _ehead = . ; + } + .rodata.compressed : { + *(.rodata.compressed) + } + .text : { + _text = .; /* Text */ + *(.text) + *(.text.*) + _etext = . ; + } + .rodata : { + _rodata = . ; + *(.rodata) /* read-only data */ + *(.rodata.*) + _erodata = . ; + } + .data : { + _data = . ; + *(.data) + *(.data.*) + _edata = . ; + } + .bss : { + _bss = . ; + *(.bss) + *(.bss.*) + *(COMMON) +#ifdef CONFIG_X86_64 + . = ALIGN(8); + _end_before_pgt = . ; + . = ALIGN(4096); + pgtable = . ; + . = . + 4096 * 6; +#endif + _ebss = .; + } +} -- cgit v1.1
