Anup Patel 6bcff51539 RISC-V: Add bitmap reprensenting ISA features common across CPUs ... This patch adds riscv_isa bitmap which represents Host ISA features common across all Host CPUs. The riscv_isa is not same as elf_hwcap because elf_hwcap will only have ISA features relevant for user-space apps whereas riscv_isa will have ISA features relevant to both kernel and user-space apps. One of the use-case for riscv_isa bitmap is in KVM hypervisor where we will use it to do following operations: 1. Check whether hypervisor extension is available 2. Find ISA features that need to be virtualized (e.g. floating point support, vector extension, etc.) Signed-off-by: Anup Patel <anup.patel@wdc.com> Signed-off-by: Atish Patra <atish.patra@wdc.com> Reviewed-by: Alexander Graf <graf@amazon.com> Signed-off-by: Palmer Dabbelt <palmerdabbelt@google.com>		2020-05-04 14:08:59 -07:00
