Successfully cross-compiled for arm (multi_v7_defconfig, GCC 12.1.0, neon
FPU) and arm64 (bcm2711_defconfig, GCC 12.1.0).
On arm64 build, I found partly outside array bounds warning:

These warnings are introduced by commit e631ddba5887833 ("[JFFS2] Add erase
block summary support (mount time improvement)") and unfortunately, initial
mainline commit at 1da177e4c3f415 ("Linux-2.6.12-rc2").
These doesn't cause build failure, however.
