* [MIPS] vmlinux.lds.S: handle .text.*Atsushi Nemoto2008-09-211-0/+1
| | | | | | | | | The -ffunction-sections puts each text in .text.function_name section. Without this patch, most functions are placed outside _text..._etext area and it breaks show_stacktrace(), etc. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* [MIPS] Do not discard extra debugging sections.Daniel Jacobowitz2007-08-271-3/+4
| | | | | | | | | | Leaving these sections is useful to some tools that look at the image, and none of them are loaded into memory. The .mdebug.abi64 section, in particular, lets GDB recognize vmlinux.32 as an N64 program instead of guessing that it is O32.

* define new percpu interface for shared dataFenghua Yu2007-07-191-4/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | per cpu data section contains two types of data. One set which is exclusively accessed by the local cpu and the other set which is per cpu, but also shared by remote cpus. In the current kernel, these two sets are not clearely separated out. This can potentially cause the same data cacheline shared between the two sets of data, which will result in unnecessary bouncing of the cacheline between cpus. One way to fix the problem is to cacheline align the remotely accessed per cpu data, both at the beginning and at the end. Because of the padding at both ends, this will likely cause some memory wastage and also the interface to achieve this is not clean. This patch: Moves the remotely accessed per cpu data (which is currently marked as ____cacheline_aligned_in_smp) into a different section, where all the data elements are cacheline aligned. And as such, this differentiates the local only data and remotely accessed data cleanly.

* [PATCH] x86: Allow percpu variables to be page-alignedJeremy Fitzhardinge2007-05-021-1/+1
| | | | | | | | | | | | | | | Let's allow page-alignment in general for per-cpu data (wanted by Xen, and Ingo suggested KVM as well). Because larger alignments can use more room, we increase the max per-cpu memory to 64k rather than 32k: it's getting a little tight.

| | | | | | | | | | | | Update all arch/*/kernel/vmlinux.lds.S to not include space for initramfs when CONFIG_BLK_DEV_INITRAMFS is not selected.

* [MIPS] Discard .exit.text and .exit.data at runtime.Ralf Baechle2006-12-121-2/+4
| | | | | | | | | | | | | | | | | | | | | 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.

* [MIPS] Use generic DWARF_DEBUGAtsushi Nemoto2006-06-011-10/+3Star
| | | | | | | | | | | 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.

* [MIPS] Discard .exit.text at runtime.Ralf Baechle2006-03-091-1/+3
| | | | | | | | | | 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 <ralf@linux-mips.org>

* Linux-2.6.12-rc2Linus Torvalds2005-04-171-0/+183
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
