[PATCH v3 3/5] x86/entry: Compile entry_SYSCALL32_ignore unconditionally
From: Nikolay Borisov
Date: Fri Jun 16 2023 - 08:58:10 EST
In upcomiing patches entry_SYSCALL32_ignore() could be used even if
CONFIG_IA32_EMULATION is selected but IA32 support is disabled either
via CONFIG_IA32_EMULATION_DEFAULT_DISABLED or the runtime override.i
Just compile it unconditionally.
