These patches are the result of cleaning some of that up a bit. They are based on top of Thomas' patches. Dave, can you have a wee look at the Atom errata thing; this does grow the amount of code between the page-table update and the TLB flush a bit, but all that PTI crud we did a while back already made it a non-trivial amount of code. --- pageattr.c | 128 ++++++++++++++++++++++--------------------------------------- 1 file changed, 48 insertions(+), 80 deletions(-)
