Subject: x86, um: sanitize uml sigcontext.h uses
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3be311e324087d94050010b97821b9d77a45e92f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

x86, um: sanitize uml sigcontext.h uses

a) the only difference between sigcontext and sysdep/sigcontext
is that the former contains externs for two long-dead functions.
Removed, switched the only user to sysdep/sigcontext

b) asm/sigcontext.h is removable - that of underlying architecture
would get used.
