Subject: [PATCH v2 00/41] linux-user: Streamline handling of SIGSEGV
Date: Sat, 18 Sep 2021 11:44:46 -0700 [thread overview]
Message-ID: <20210918184527.408540-1-richard.henderson@linaro.org> (raw)
Based-on: 20210915174951.1852266-1-richard.henderson@linaro.org
("linux-user/nios2: trap and kuser fixes")
... which itself is
Based-on: 20210813131809.28655-1-peter.maydell@linaro.org
("linux-user: Clean up siginfo_t handling for arm, aarch64")
... for force_sig_fault().
and in turn based on my current tcg-next pull, for has_work changes.
For avoidance of doubt:
https://gitlab.com/rth7680/qemu/-/commits/lu-hostsig-2
Only 4 of 20 targets need any special code for correctly
signalling SIGSEGV, and the host-level code is reduced as well.
Dropped the rfc, but still seeking feedback the factorization.
