This patch series tidies up a few bits ofthe nested p2m code. The main thing it does is reorganize the locking so that most of the changes to nested p2m tables happen only under the p2m lock, and the nestedp2m lock is only needed to reassign p2m tables to new cr3 values. Changes since v1: - a few minor fixes - more sensible flushing policy in p2m_get_nestedp2m() - smoke-tested this time!

Hi! Attached patch removes gfn_to_mfn_current(). It is redundant and effectively unused. All remaining users now use proper replacement function. => No functional change. While here, silence stdvga and use page_mode_hap() consequently.

Hi, Attached patch implements the VMCB cleanbits SVM feature. Upcoming AMD CPUs introduce them and they are basically hints for the CPU which vmcb values can be re-used from the previous VMRUN instruction. Each bit represents a certain set of fields in the VMCB. Setting a bit tells the cpu it can re-use the cached value from the previous VMRUN. Clearing a bit tells the cpu to reload the values

For compiling the xen kernel we use -nostdinc which means we don''t want to rely on any external headers. That also counts vor stdarg.h. Use the external header when we compile the tools. Adapt libelf-loader.c which is compiled in the kernel and with the tools. Signed-off-by: Christoph Egger <Christoph.Egger@amd.com> -- ---to satisfy European Law for business letters: Advanced

Having an absolute path in a #include confuses distcc''s pump mode. Since AFAICS OpenBSD''s stdarg handling uses the builtins, I think we should just treat it like we do NetBSD.

This patch series includes a series of bugs related to p2m, ept, and PoD code which were found as part of our XenServer product testing. Each of these fixes actual bugs, and the 3.4-based version of the patch has been tested thoroughly. (There may be bugs in porting the patches, but most of them are simple enough as to make it unlikely.) Each patch is conceptually independent, so they can each

Intercepting this MSR is pointless - The swapgs instruction does not cause a vmexit, so the cached result of this is potentially stale after the next guest instruction. It is correctly saved and restored on vcpu context switch. Furthermore, 64bit Windows writes to this MSR on every thread context switch, so interception causes a substantial performance hit.
