Subject: [PATCH] init/Kconfig: Remove USELIB syscall by default
Date: Tue, 12 Apr 2022 14:25:20 -0700 [thread overview]
Message-ID: <20220412212519.4113845-1-keescook@chromium.org> (raw)
The uselib syscall has been long deprecated. There's no need to keep
this enabled by default under X86_32.

+ default ALPHA || M68K || SPARC
help
This option enables the uselib syscall, a system call used in the
dynamic linker from libc5 and earlier. glibc does not use this
