Subject: [PATCH 0/2] A couple of build fixes for x86 when using GCC 15

Hi all,

GCC 15 changed the default C standard version from gnu17 to gnu23, which
reveals a few places in the kernel where a C standard version was not
set, resulting in build failures because bool, true, and false are
reserved keywords in C23 [1][2]. Update these places to use the same C
standard version as the rest of the kernel, gnu11.
