2022-01-28bsd-user/signal-common.h: Move signal functions prototypes to hereWarner Losh

2022-01-28bsd-user/arm/target_arch_cpu.h: Move EXCP_ATOMIC to match linux-userWarner Losh
Move the EXCP_ATOMIC case to match linux-user/arm/cpu_loop.c:cpu_loop ordering. Signed-off-by: Warner Losh <imp@bsdimp.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
2022-01-28bsd-user/arm/signal.c: get_mcontext should zero vfp dataWarner Losh
FreeBSD's get_mcontext doesn't return any vfp data. Instead, it zeros out the vfp feilds (and all the spare fields). Impelement this behavior. We're still missing the sysarch(ARM_GET_VFPCONTEXT) syscall, though. Signed-off-by: Warner Losh <imp@bsdimp.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
2022-01-28bsd-user/arm/signal.c: Implement setup_sigframe_arch for armWarner Losh
Fix the broken context setting for arm. FreeBSD's get_mcontext does not fill in the vfp info. It's filled in in sigframe(). This corresponds to the new setup_sigframe_arch which fills in mcontext, then adjusts it to point to the vfp context in the sigframe and fills in that context as well. Add pointer to where this code is done. Signed-off-by: Warner Losh <imp@bsdimp.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org>
