MIPS: asm/reg.h: Make 32- and 64-bit definitions available at the same time 2014-07-30T21:27:40+00:00 Alex Smith alex@alex-smith.me.uk 2014-07-23T13:40:08+00:00 bcec7c8da6b092b1ff3327fd83c2193adb12f684 Get rid of the WANT_COMPAT_REG_H test and instead define both the 32- and 64-bit register offset definitions at the same time with MIPS{32,64}_ prefixes, then define the existing EF_* names to the correct definitions for the kernel's bitness. This patch is a prerequisite of the following bug fix patch.

MIPS{32,64}_ prefixes, then define the existing EF_* names to the
correct definitions for the kernel's bitness.

MIPS: 64-bit: Fix o32 core dump 2009-07-03T14:45:27+00:00 Yong Zhang yong.zhang@windriver.com 2009-07-01T01:35:39+00:00 cad9bc69048b073023366ebb0878c1dd64a2c4d9 If an o32 process generates a core dump on a 64 bit kernel, the core file will not be correctly recognized. This is because ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS are not correctly defined for o32 and will use the default register set which would be CONFIG_64BIT in asm/elf.h. So we'll switch to use the right register defines in this situation by checking for WANT_COMPAT_REG_H and use the right defines of ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS.
