early_times.h -- it means before every feature offered by the kernel
is available or 100% trustable, thus ASM because it is also supposed
to fix what is broken in the kernel thus using the kernel macros isn't
the correct way to do so. Early times means before the kernel, thus
also out-of-it-three or feature support. Them asm (isb) sounds too
drastic or not enough for "exhotic" arm arch? It is a template to
start with, not a working part of the kernel. When the kernel works,
!0 == true is true.

The concept remains the same: a register counter read protected by
fencing. Not more, not less than the essential. And a bucket
out-of-the-three as a starting point **before** the kernel is ready or
fixed. Written in this way, does it sound more reasonable?
