6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yong-Xuan Wang <yongxuan.wang@xxxxxxxxxx>
commit 564fc8eb6f78e01292ff10801f318feae6153fdd upstream.
The init_rt_signal_env() funciton is called before the alternative patch
is applied, so using the alternative-related API to check the availability
of an extension within this function doesn't have the intended effect.
This patch reorders the init_rt_signal_env() and apply_boot_alternatives()
to get the correct signal_minsigstksz.
Fixes: e92f469b0771 ("riscv: signal: Report signal frame size to userspace via auxv")
