This set of patches converts the way frames gets created from using PUSHes/POPs to using MOVes, thus allowing (in certain cases) to avoid saving/restoring part of the register set. While the place where the (small) win from this comes from varies between CPUs, the net effect is a 1 to 2% reduction on a combined interruption entry and exit when the full state save can be avoided. 1: use MOV

From: Sylvain Gault <sylvain.gault at gmail.com> On some architecture, including my hardware, the function ExitBootServices may need to be called twice in order to successfully exit the boot services. As stated by the UEFI spec, the first call to ExitBootServices may perform a partial shutdown of the services. It seems that during this partial shutdown, the memory map can be modified, thus

This makes sense as long as no other functions get added after this that might want to allocate more RAM. This function looks good from he...

Here is an slightly updated version of the paravirt_ops patch. If your comments and criticism were welcome before, now it's even more! There are some issues that are _not_ addressed in this revision, and here are the causes: * split debugreg into multiple functions, suggested by Andi: - Me and jsfg agree that introducing more pvops (specially 14!) is not worthwhile. So, although we do

This is hopefully the last iteration of the pvops64 patch. >From the last version, we have only one change, which is include/asm-x86_64/processor.h: There were still one survivor in raw asm. Also, git screwed me up for some reason, and the 25th patch was missing the new files, paravirt.{c,h}. (although I do remember having git-add'ed it, but who knows...) Andrew, could you please push it

Hey folks, This is the part-of-pvops-implementation-that-is-not-exactly-a-merge. Neat, uh? This is the majority of the work. The first patch in the series does not really belong here. It was already sent to lkml separetedly before, but I'm including it again, for a very simple reason: Try to test the paravirt patches without it, and you'll fail miserably ;-) (and it was not yet
