[Xen-devel] XSAVE flavors

Shuai, originally I only meant to inquire about the state of the promised alternatives improvement to the XSAVE code. However, while looking over the code in question again I stumbled across a separate issue: XSAVES, just like XSAVEOPT, may use the "modified" optimization. However, the fcs and

[Xen-devel] [PULL 3/8] xen: Switch to libxengnttab interface for compat shims.

From: Ian Campbell In Xen 4.7 we are refactoring parts libxenctrl into a number of separate libraries which will provide backward and forward API and ABI compatiblity. One such library will be libxengnttab which provides access to grant tables. In preparation for this

[Xen-devel] [PULL 1/8] xen_console: correctly cleanup primary console on teardown.

From: Ian Campbell All of the work in con_disconnect applies to the primary console case (when xendev->dev is NULL). Therefore remove the early check and bail and allow it to fall through. All of the existing code is correctly conditional already. The ->dev and
