* [MIPS] Add basic SMARTMIPS ASE supportFranck Bui-Huu2007-02-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds trivial support for SMARTMIPS extension. This extension is currently implemented by 4KS[CD] CPUs. Basically it saves/restores ACX register, which is part of the SMARTMIPS ASE, when needed. This patch does *not* add any support for Smartmips MMU features. Futhermore this patch does not add explicit support for 4KS[CD] CPUs since they are respectively mips32 and mips32r2 compliant. So with the current processor configuration, a platform that has such CPUs needs to select both configs: CPU_HAS_SMARTMIPS SYS_HAS_CPU_MIPS32_R[12] This is due to the processor configuration which is mixing up all the architecture variants and the processor types. The drawback of this, is that we currently pass '-march=mips32' option to gcc when building a kernel instead of '-march=4ksc' for 4KSC case. This can lead to a kernel image a little bit bigger than required. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* [MIPS] Fix struct sigcontext for N32 userlandAtsushi Nemoto2007-02-201-17/+16
| | | | | | | | | | The kernel use 64-bit for sc_regs[0], and both N32/N64 userland expects it was 64-bit. But size of 'long' on N32 is actually 32-bit. So this definition make some confusion. Use __u32 and __u64 for N32/N64 sigcontext to get rid of this confusion. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* [MIPS] signal32: no need to save c0_status register in setup_sigcontext32()Franck Bui-Huu2007-02-101-2/+2
| | | | | | | | | | | | | | | All the information in the MIPS c0_status register is priviledged. Nothing that would constitute part of the thread context. The one flag one could possibly argument about might be c0_status.fr but none of the ABIs or tools or application software can make use of it. So for consistency with restore_sigcontext32(), which does not restore c0_status register, this patch remove the saving part.

* [MIPS] Update struct sigcontext member namesDaniel Jacobowitz2006-06-011-2/+8
| | | | | | | | Rename the 64-bit sc_hi and sc_lo arrays to use the same names as the 32-bit struct sigcontext (sc_mdhi, sc_hi1, et cetera). Signed-off-by: Daniel Jacobowitz <dan@codesourcery.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

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!
