# \[PATCH 11/20\] x86: entry: add do\_SYSENTER\_32() prototype - From: Arnd Bergmann \ - Date: 2023-05-16 19:37:52 - List: linux-trace-kernel - Page: https://ratatoskr.run/linux-trace-kernel/2023/05/2199806 - Thread: https://ratatoskr.run/linux-trace-kernel/2023/05/2199796/t.md ```text From: Arnd Bergmann The 32-bit system call entry points can be called on both 32-bit and 64-bit kernels, but on the former the declarations are hidden: arch/x86/entry/common.c:238:24: error: no previous prototype for 'do_SYSENTER_32' [-Werror=missing-prototypes] Move them all out of the #ifdef block to avoid the warnings.
