This commit adds a new convention that requires devs to
write a comment for headers that have a manpage tied to them
that shows which manpage it is tied to.

This commit moves the interrupts_init() and gdt_load()
calls to the top so interrupts are set up first in case
something goes wrong so we can get information from
exception handlers.

This commit makes the output header from tools/ksyms contain header guards

This commit wraps __KERNEL_META for .S files within a conditional. Only
makes it easier to trace if on a different architecture and it is not
implemented for it; however, this macro could perhaps be placed in a
better header (XXX)? This should work for now.

This commit introduces memory barriers to MMIO read/write helpers to
ensure the compiler does not re-order these critical memory accesses
which would in turn result in very strange behaviour if it were to be
re-ordered.

This commit fixes a spinlock_acquire() flaw and corrects
a [quite an implausible] mistake, in which we do not even
spin. It would have been fine how it was before in Vega's
contemporary state; however, not a good idea to keep.

Add spectre mitigation support for AMD64 hosts which may be enabled via
the --enable-spectre-mitigation configure flag. This commit currently
only adds IBRS support but more techniques may be added later on.

This commit adds a __STATIC_ASSERT which wraps over
_Static_assert() to be more consistent with Vega style.

This commit makes the hpet_sleep() function return either
EXIT_SUCCESS or EXIT_FAILURE instead of hardcoded constants.

This commit makes msleep(), usleep(), etc, return an
error code of either EXIT_SUCCESS or EXIT_FAILURE for
error handling. This commit also makes the calibrate()
routine return a frequency (ideally in Hz), however, it is
optional and can return 0 as a way of saying it doesn't return
one.

This commit introduces a new timer abstraction that is architecture-independent.
It enables the registration and request of timers in a consistent and uniform manner
abstracting away architectural details.
