Merge remote-tracking branch 'upstream/master' into queue
Merge reason: From: Alexander Graf <agraf@suse.de> "Just recently this really important patch got pulled into Linus' tree for 3.9: commit 1674400aaee5b466c595a8fc310488263ce888c7 Author: Anton Blanchard <anton <at> samba.org> Date: Tue Mar 12 01:51:51 2013 +0000 Without that commit, I can not boot my G5, thus I can't run automated tests on it against my queue. Could you please merge kvm/next against linus/master, so that I can base my trees against that?" * upstream/master: (653 commits) PCI: Use ROM images from firmware only if no other ROM source available sparc: remove unused "config BITS" sparc: delete "if !ULTRA_HAS_POPULATION_COUNT" KVM: Fix bounds checking in ioapic indirect register reads (CVE-2013-1798) KVM: x86: Convert MSR_KVM_SYSTEM_TIME to use gfn_to_hva_cache functions (CVE-2013-1797) KVM: x86: fix for buffer overflow in handling of MSR_KVM_SYSTEM_TIME (CVE-2013-1796) arm64: Kconfig.debug: Remove unused CONFIG_DEBUG_ERRORS arm64: Do not select GENERIC_HARDIRQS_NO_DEPRECATED inet: limit length of fragment queue hash table bucket lists qeth: Fix scatter-gather regression qeth: Fix invalid router settings handling qeth: delay feature trace sgy-cts1000: Remove __dev* attributes KVM: x86: fix deadlock in clock-in-progress request handling KVM: allow host header to be included even for !CONFIG_KVM hwmon: (lm75) Fix tcn75 prefix hwmon: (lm75.h) Update header inclusion MAINTAINERS: Remove Mark M.
