pc, pci, misc bugfixes A bunch of bugfixes for 2.2. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> # gpg: Signature made Mon 24 Nov 2014 18:59:47 GMT using RSA key ID D28D5469 # gpg: Good signature from "Michael S. Tsirkin <mst@kernel.org>" # gpg: aka "Michael S. Tsirkin <mst@redhat.com>" * remotes/mst/tags/for_upstream: pc: acpi: mark all possible CPUs as enabled in SRAT pcie: fix improper use of negative value pcie: fix typo in pcie_cap_deverr_init() target-i386: move generic memory hotplug methods to DSDTs acpi-build: mark RAM dirty on table update hw/pci: fix crash on shpc error flow pc: count in 1Gb hugepage alignment when sizing hotplug-memory container pc: explicitly check maxmem limit when adding DIMM pc: pc-dimm: use backend alignment during address auto allocation pc: align DIMM's address/size by backend's alignment value memory: expose alignment used for allocating RAM as MemoryRegion API pc: limit DIMM address and size to page aligned values pc: make pc_dimm_plug() more readble pc: kvm: check if KVM has free memory slots to avoid abort() qemu-char: fix tcp_get_fds Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
