fix riscv64 elf_fpregset_t type and member names mismatch in order for sys/procfs.h (provided by sys/user.h) to be useful, it needs to match the API its consumers (gdb, etc.) expect, including the member names established by glibc. this partly reverts commit 29e8737f81ccc9fbadcf61a75318aa3d0516aafa, which partly reverted d493206de7df4db07ad34f24701539ba0a6ed38c, eliminating struct user_fpregs_struct which seems to have had no precedent and using union __riscv_mc_fp_state for elf_fpregset_t. this requires indirect inclusion of signal.h to make union __riscv_mc_fp_state visible, but being that these are nonstandard "junk" headers with no official restrictions on what they can pull in, that's no big deal. split off and expanded from patch by Khem Raj. 2019-09-30 03:45:47 +00:00			`#include <signal.h>`
re-add ELF gregs and fpregs types to riscv64 user.h d493206de7df4db07ad34f24701539ba0a6ed38c deleted all the content of user.h, but sys/procfs.h expects this from sys/user.h threfore we retain the non conflicting parts 2019-08-14 01:07:16 +00:00
