they had small conflicts (respectively within KVM documentation, and with 3.16-rc changes). Since they were all within the subsystem, I took care of them. Stephen Rothwell reported some snags in PPC builds, but they are all fixed now; the latest linux-next report was clean. New features for ARM include: - KVM VGIC v2 emulation on GICv3 hardware - Big-Endian support for arm/arm64 (guest and host) - Debug Architecture support for arm64 (arm32 is on Christoffer's todo list) And for PPC: - Book3S: Good number of LE host fixes, enable HV on LE - Book3S HV: Add in-guest debug support This release drops support for KVM on the PPC440. As a result, the PPC merge removes more lines than it adds. :) I also included an x86 change, since Davidlohr tied it to an independent bug report and the reporter quickly provided a Tested-by; there was no reason to wait for -rc2. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJT4iIJAAoJEBvWZb6bTYbyZqoP/3Wxy8NWPFJ8HGt81NHlGnDS a9UbL7EibcOEG+aaKqmtBglTD5YDiGBDNCxxiSJaDHt+grLN4fsWIliJob1nJFoO 90f89EWN2XjeCrJXA5nUoeg5tpc5OoYKsiP6pTgzIwkP8vvs/H1+zpcTS/UmYsr/ qipVMMsM+zZeHWZcSbqjW88z7YqIn1sr5282wJ85cbyv4KGizb/G4dyPuDqLb6np hkAD8Ah6VV2suQ2FSy7G2fg20R0vglUi60hkEHLoCBPVqJCl7SmC8MvxNbjBnP8S J36R0R0u1wHYKzAGooLJGVOZ/o/gSiVqKX+++L2EvJBN+kuA6u/7fxLyBT+LwDAE IF/Aln5rpg1fe+eywvhz86WljTVEQ8bO1zVsIQUPY+/ZOPedZHMwyvXft8ogbjSp 2m9OJ/3e8Aggh0OeHpCDoeow+QDUXvX0YdCw+2Yh0p+7VMXqkyp0QEiBu38jrusC rB3VNifJbDSWLKdG9LfCAPHnxZD2XYEwv2WFBo6KQOGMGHfx0GXpCOL/jQihrhA6 HtEG5Bs3lvnHQemdpUZ58xojiABbMaUPdcnPXQQEp23WhZzrfLMLzqVG0VYnhSsC 9pi7MJj8c31rqx5WU2oRM28i/BvNxN0NCtkDpineO5s3f89Ws1xnwxqlm38AKP0J irJQTYFEqec+GM9JK1rG =hyQP -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull second round of KVM changes from Paolo Bonzini: "Here are the PPC and ARM changes for KVM, which I separated because they had small conflicts (respectively within KVM documentation, and with 3.16-rc changes).
