[PATCH] disable init/initramfs.c: architectures

2007-02-11T18:51:25Z

Update all arch/*/kernel/vmlinux.lds.S to not include space for initramfs when CONFIG_BLK_DEV_INITRAMFS is not selected. This saves another 4 kbytes on most platfoms (some reserve PAGE_SIZE for initramfs). Signed-off-by: Jean-Paul Saman Cc: Al Viro Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[MIPS] Discard .exit.text and .exit.data at runtime.

2006-12-12T01:46:24Z

While the recent cset 86384d544157db23879064cde36061cdcafc6794 did improve things it didn't resolve all the problems. So bite the bullet and discard .exit.text and .exit.data at runtime. Which of course sucks because it bloats binaries with code that will never ever be used but it's the only thing that will work reliable as demonstrated by the function sd_major() in drivers/scsi/sd.c. Gcc may compile sd_major() using a jump table which it will put into .rodata. If it also inlines sd_major's function body into exit_sd() which gcc > 3.4.x does. If CONFIG_BLK_DEV_SD has been set to y we would like ld to discard exit_sd's code at link time. However sd_major happens to contain a switch statement which gcc will compile using a jump table in .rodata on the architectures I checked. So, when ld later discards .exit.text only the jump table in .rodata with its stale references to the discard .exit.text will be left which any no antique ld will honor with a link error.

[PATCH] vmlinux.lds: consolidate initcall sections

2006-10-27T22:34:51Z

Add a vmlinux.lds.h helper macro for defining the eight-level initcall table, teach all the architectures to use it. This is a prerequisite for a patch which performs initcall synchronisation for multithreaded-probing.

[MIPS] Use generic DWARF_DEBUG

2006-05-31T23:28:32Z

When debugging a kernel compiled by gcc 4.1 with gdb 6.4, gdb could not show filename, linenumber, etc. It seems fixed if I used generic DWARF_DEBUG macro. Although gcc 3.x seems work without this change, it would be better to use the generic macro unless there were something MIPS specific. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

[MIPS] Discard .exit.text at runtime.

2006-03-09T18:05:09Z

At times gcc will place bits of __exit functions into .rodata. If compiled into the kernle itself we used to discard .exit.text - but not the bits left in .rodata. While harmless this did at times result in a large number of warnings. So until gcc fixes this, discard .exit.text at runtime. Signed-off-by: Ralf Baechle
