Something is wrong with asm/unaligned.h on my system, if I do the
following change it builds properly:

diff --git a/lib/vdso/getrandom.c b/lib/vdso/getrandom.c
index b230f0b10832..c1a18f5c6fe3 100644
--- a/lib/vdso/getrandom.c

 #include <uapi/linux/mman.h>

 #define MEMCPY_AND_ZERO_SRC(type, dst, src, len) do {
         \

My system is based on meteor lake, not sure if that is affecting the
build with a mix of LP+E+P cores?
