The following commit has been merged into the x86/entry branch of tip: Commit-ID: 370dcd58548a360bbf8a65b89b410d09f56bf0c6 Gitweb: https://git.kernel.org/tip/370dcd58548a360bbf8a65b89b410d09f56bf0c6 Author: Nikolay Borisov <nik.borisov@suse.com> AuthorDate: Fri, 23 Jun 2023 14:14:06 +03:00 Committer: Thomas Gleixner <tglx@linutronix.de> CommitterDate: Thu, 14 Sep 2023 13:19:53 +02:00 x86/entry: Compile entry_SYSCALL32_ignore() unconditionally To limit the IA32 exposure on 64bit kernels while keeping the flexibility for the user to enable it when required, the compile time enable/disable via CONFIG_IA32_EMULATION is not good enough and will be complemented with a kernel command line option. Right now entry_SYSCALL32_ignore() is only compiled when CONFIG_IA32_EMULATION=n, but boot-time enable- / disablement obviously requires it to be unconditionally available. Remove the #ifndef CONFIG_IA32_EMULATION guard.
