This reverts commit 9e13f189d8961a8f9c8befb4d2d693121fa1876c.
As the commit message says, "This test works with GCC under unit test but
not in the kernel build." And indeed, the aarch64 build fails with:
fs/inode.c: In function ‘new_inode’:
./arch/arm64/include/asm/processor.h:155:2: error: invalid 'asm': invalid operand
asm volatile("prfm pstl1keep, [%x0]\n" : : "p" (ptr));
Revert it, and wait for the proper prfm fix.
