...XCR_XFEATURE_ENABLED_MASK may change XSAVE related cpuid leave return values. The volatile prefix is required to avoid the second cpuid calls following some possible changing operations being optimized in incorrect way by compiler. The sample bug is in xsave_init while debug=n. The second call to cpuid_count() may be optimized and lead to a BUG_ON case while compare xsave_cntxt_size with ebx.

Hi Andrew, This series of patches lays the basic ground work for the paravirtualized kernel patches coming later on. I think this lot is ready for the rough-and-tumble world of the -mm tree. The main change from the last posting is that all the page-table related patches have been moved out, and will be posted separately. Also, the off-by-one in reserving the top of address space has been

Hi all, I've been looking at finding common ground between the VMI, Xen and other paravirtualization approaches, and after some discussion, we're getting somewhere. These first two patches are the fundamentals, stolen mainly from the VMI patches: removing assumptions about the kernel running in ring 0, and macro-izing all the obvious para-virtualize-needing insns. The third patch is

The first patch really isn''t as much of a follow-up than what triggered the security issues to be noticed in the first place. 1: x86: preserve FPU selectors for 32-bit guest code 2: x86: fix XCR0 handling 3: x86/xsave: adjust state management 4: x86/fxsave: bring in line with recent xsave adjustments The first two I would see as candidates for 4.3 (as well as subsequent backporting,

From: Matt Fleming <matt.fleming at linux.intel.com> This series fixes some bugs and switches the elflink branch to be entirely ELF modules. It applies on top of, http://syslinux.zytor.com/archives/2011-April/016369.html The deletions in the diff stat below are mainly from deleting com32/elflink/modules (finally!). Now there should be no duplicate code because we don't need COM32 and
