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.
Hello x86 maintainers!
I think this would be valuable to get into -rc1 since we're getting very close to a GCC 15 release. Can someone get this into -tip urgent, please? If everyone is busy I can take it via the hardening tree, as we appear to be the ones tripping over it the most currently. :)
