    Subject[patch 01/10] x86/entry/32: Add missing ASM_CLAC to general_protection entry
    All exception entry points must have ASM_CLAC right at the
    beginning. The general_protection entry is missing one.

    Fixes: e59d1b0a2419 ("x86-32, smap: Add STAC/CLAC instructions to 32-bit kernel entry")
