linux-stable.git/arch/arm64/kernel/process.c, branch v3.7 Linux kernel stable tree arm64: elf: fix core dumping definitions for GP and FP registers 2012-11-08T16:06:20+00:00 Will Deacon will.deacon@arm.com 2012-11-06T19:28:48+00:00 6ba1bc826d160fe4f32bcb188687dcca4bdfaf3d struct user_fp does not exist for arm64, so use struct user_fpsimd_state instead for the ELF core dumping definitions. Furthermore, since we use regset-based core dumping, we do not need definitions for dump_task_regs and dump_fpu.

The context switching CPU specific code is introduced with the CPU support patch (part of the arch/arm64/mm/proc.S file). AArch64 supports ASID-tagged TLBs and the ASID can be either 8 or 16-bit wide (detectable via the ID_AA64AFR0_EL1 register).
