Raw Normal View History

Linux-2.6.12-rc2 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!

[MIPS] Unify mips_fpu_soft_struct and mips_fpu_hard_structs. 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>

* Further private data for which no space exists in mips_fpu_struct.
* This should be subsumed into the mips_fpu_struct structure as

MIPS: Switch FPU emulator trap to BREAK instruction. Arguably using the address error handler has always been ugly. But with processors that handle unaligned loads and stores in hardware the current mechanism ceases to work so switch it to a BREAK instruction and allocate break code 514 to the FPU emulator.
