I tested kernel version 6.18.25-rc1 by building and booting it in
a virtual environment on both x86_64 and arm64 architectures.

Build and boot testing was performed on version 6.18.25-rc1 using the
default configuration on both x86_64 and arm64 architectures in
a virtual environment. The kernel built and booted successfully,
and no dmesg regressions were observed.

kernel version: 6.18.25-rc1
Configurations: x86_64_defconfig, defconfig
Architectures: arm64, x86_64
Kernel Source: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git
