SubjectRe: [PATCH v3 1/2] x86/mm: Identify the end of the kernel area to be reserved
I've updated the bug some more with more info

I can't replicate this on RHEL7 with GCC 4.8.5 or GCC 7.3.1

My GCC is as follows:

Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-pc-linux-gnu/9.2.0/lto-wrapper
Target: x86_64-pc-linux-gnu
Configured with:
/var/tmp/portage/sys-devel/gcc-9.2.0/work/gcc-9.2.0/configure
--host=x86_64-pc-linux-gnu --build=x86_64-pc-linux-gnu --prefix=/usr
--bindir=/usr/x86_64-pc-linux-gnu/gcc-bin/9.2.0
--includedir=/usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/include

--disable-isl-version-check --enable-default-pie --enable-default-ssp
Thread model: posix
gcc version 9.2.0 (Gentoo 9.2.0 p1)

Could this be related to the --enable-default-ssp or --enable-default-pie?
