[MIPS] die(): Properly declare as non-returning

2007-07-04T14:53:15Z

This marks the declaration of die() correctly, removing "control reaches end of non-void function" warnings from non-void functions that die() at the end. Signed-off-by: Maciej W. Rozycki Signed-off-by: Ralf Baechle

[MIPS] Add basic SMARTMIPS ASE support

2007-02-22T00:50:44Z

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 Signed-off-by: Ralf Baechle

[MIPS] Move die and die_if_kernel() from system.h to ptrace.h

2006-12-10T21:52:11Z

This eleminates the need to include ptrace.h into system.h and fixes a harmless namespace conflict on the PC symbol in bpck.c. Signed-off-by: Ralf Baechle

[MIPS] Use conditional traps for BUG_ON on MIPS II and better.

2006-11-30T01:14:50Z

This shaves of around 4kB and a few cycles for the average kernel that has CONFIG_BUG enabled. Signed-off-by: Ralf Baechle

[MIPS] Let gcc align 'struct pt_regs' on 8 bytes boundary

2006-10-03T16:59:17Z

The stack pointer in MIPS/gcc should always 8 bytes aligned on entry to any routines. Therefore pt_regs structure must be aligned to 8-byte boundary too. Instead of creating dummy fields to achieve this alignment, this patch let gcc doing it. Therefore 'smtc_pad' field can be safely removed. Signed-off-by: Franck Bui-Huu Signed-off-by: Ralf Baechle
