* [MIPS] Simplify dump_stack()Franck Bui-Huu2006-09-271-11/+9
| | | | | | | | | | Make dump_stack() code not depend on CONFIG_KALLSYMS. It also make prepare_frametrace() always inlined to get less false entries reported by show_raw_backtrace(). Signed-off-by: Franck Bui-Huu <vagabon.xyz@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* [MIPS] Miscellaneous cleanup in prologue analysis codeFranck Bui-Huu2006-09-271-19/+14
| | | | | | | | | | | We usually use backtrace term for dumping a call tree during debug. Therefore this patch renames show_frametrace() into show_backtrace() and show_trace() into show_raw_backtrace(). It also uses the new function print_ip_sym().

* [MIPS] dump_stack() based on prologue code analysisAtsushi Nemoto2006-09-271-12/+86
| | | | | | | | | | Instead of dump all possible address in the stack, unwind the stack frame based on prologue code analysis, as like as get_wchan() does. While the code analysis might fail for some reason, there is a new kernel option "raw_show_trace" to disable this feature.

* [MIPS] Rearrange show_stack, show_traceAtsushi Nemoto2006-09-271-28/+23

| | | | | | | | | The struct mips_fpu_soft_struct and mips_fpu_hard_struct are completely same now and the kernel fpu emulator assumes that. This patch unifies them to mips_fpu_struct and get rid of mips_fpu_union. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* [MIPS] Rewrite all the assembler interrupt handlers to C.Ralf Baechle2006-04-191-0/+2
| | | | | | | | | | | | Saves like 1,600 lines of code, is way easier to debug, compilers frequently do a better job than the cut and paste type of handlers many boards had. And finally having all the stuff done in a single place also means alot of bug potencial for the MT ASE is gone. The only surviving handler in assembler is the DECstation one; I hope Maciej will rewrite it. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+1062
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!
