From: Steven Rostedt (VMware) <rostedt at goodmis.org> In discussing a build failure on x86_32 due to the use of roundup() on a 64 bit number, I realized that there's no generic equivalent roundup_64(). It is implemented in two separate places in the kernel, but there really should be just one that all can u...

Hi folks, After some time away from it, and a big rebase as a consequence, here is the updated version of paravirt_ops for x86_64, heading to inclusion. Your criticism is of course, very welcome. Have fun -- arch/x86_64/Kconfig | 11 arch/x86_64/ia32/syscall32.c | 2 arch/x86_64/kernel/Makefile | 1 arch/x86_64/kernel/apic.c | 2

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

Hi, This series corresponds do older patches in the paravirt series that was neither already applied, nor I will touch again. In general, they do not touch code that can be unified (at least, without being the unification a big problem on its own). They passed through this list a lot of times, so I feel them ready for inclusion, unless someone opposes. As with the other patches, they apply to

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, Here's a new spin of the pvops64 patch series. We didn't get that many comments from the last time, so it should be probably almost ready to get in.

From: Steven Rostedt (VMware) <rostedt at goodmis.org> When running function tracing on a Linux guest running on VMware Workstation, the guest would crash.
