/* Because kmalloc only guarantees 8-byte alignment for kmalloc'd data,
and GCC only guarantees 8-byte alignment for stack locals, we can't
be assured of 16-byte alignment for atomic lock data even if we
specify "__attribute ((aligned(16)))" in the type declaration. So,
we use a struct containing an array of four ints for the atomic lock
type and dynamically select the 16-byte aligned int from the array
for the semaphore. */
for the semaphore. */
/* From: "Jim Hull" <jim.hull of hp.com>
I've attached a summary of the change, but basically, for PA 2.0, as
long as the ",CO" (coherent operation) completer is implemented, then the
16-byte alignment requirement for ldcw and ldcd is relaxed, and instead
they only require "natural" alignment (4-byte for ldcw, 8-byte for
ldcd).
Although the cache control hint is accepted by all PA 2.0 processors,
it is only implemented on PA8800/PA8900 CPUs. Prior PA8X00 CPUs still
require 16-byte alignment. If the address is unaligned, the operation
of the instruction is undefined. The ldcw instruction does not generate
unaligned data reference traps so misaligned accesses are not detected.
This hid the problem for years. So, restore the 16-byte alignment dropped
by Kyle McMartin in "Remove __ldcw_align for PA-RISC 2.0 processors". */
