This patch adds support for kvm_gfn_to_hva_cache_init functions for reads and writes that will cross a page. If the range falls within the same memslot, then this will be a fast operation. If the range is split between two memslots, then the slower kvm_read_guest and kvm_write_guest are used. Tested: Test against kvm_clock unit tests.

Pull networking fixes from David Miller: 1) Fix erroneous sock_orphan() leading to crashes and double kfree_skb() in NFC protocol. From Thierry Escande and Samuel Ortiz. 2) Fix use after free in remain-on-channel mac80211 code, from Johannes Berg. 3) nf_reset() needs to reset the NF tracing cookie, otherwise we can leak it from one namespace into another. Fix from Gao Feng and Patrick McHardy. 4) Fix overflow in channel scanning array of mwifiex driver, from Stone Piao. 5) Fix loss of link after suspend/shutdown in r8169, from Hayes Wang. 6) Synchronization of unicast address lists to the undelying device doesn't work because whether to sync is maintained as a boolean rather than a true count. Fix from Vlad Yasevich. 7) Fix corruption of TSO packets in atl1e by limiting the segmented packet length. From Hannes Frederic Sowa. 8) Revert bogus AF_UNIX credential passing change and fix the coalescing issue properly, from Eric W Biederman. 9) Changes of ipv4 address lifetime settings needs to generate a notification, from Jiri Pirko. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (22 commits) netfilter: don't reset nf_trace in nf_reset() net: ipv4: notify when address lifetime changes ixgbe: fix registration order of driver and DCA nofitication af_unix: If we don't care about credentials coallesce all messages Revert "af_unix: dont send SCM_CREDENTIAL when dest socket is NULL" bonding: remove sysfs before removing devices atl1e: limit gso segment size to prevent generation of wrong ip length fields net: count hw_addr syncs so that unsync works properly. r8169: fix auto speed down issue netfilter: ip6t_NPT: Fix translation for non-multiple of 32 prefix lengths mwifiex: limit channel number not to overflow memory NFC: microread: Fix build failure due to a new MEI bus API iwlwifi: dvm: fix the passive-no-RX workaround netfilter: nf_conntrack: fix error return code NFC: llcp: Keep the connected socket parent pointer alive mac80211: fix idle handling sequence netfilter: nfnetlink_acct: return -EINVAL if object name is empty netfilter: nfnetlink_queue: fix error return code in nfnetlink_queue_init() netfilter: reset nf_trace in nf_reset mac80211: fix remain-on-channel cancel crash ...

eboot.o and efi_stub_$(BITS).o didn't get added to "targets", and hence their .cmd files don't get included by the build machinery, leading to the files always getting rebuilt. Rather than adding the two files individually, take the opportunity and add $(VMLINUX_OBJS) to "targets" instead, thus allowing the assignment at the top of the file to be shrunk quite a bit. At the same time, remove a pointless flags override line - the variable assigned to was misspelled anyway, and the options added are meaningless for assembly sources. [ hpa: the patch is not minimal, but I am taking it for -urgent anyway since the excess impact of the patch seems to be small enough. ] Signed-off-by: NJan Beulich <jbeulich@suse.com> Link: http://lkml.kernel.org/r/515C5D2502000078000CA6AD@nat28.tlf.novell.com Cc: Matthew Garrett <mjg@redhat.com> Cc: Matt Fleming <matt.fleming@intel.com> Signed-off-by: NH.

Commit 130549fe ("netfilter: reset nf_trace in nf_reset") added code to reset nf_trace in nf_reset(). This is wrong and unnecessary. nf_reset() is used in the following cases: - when passing packets up the the socket layer, at which point we want to release all netfilter references that might keep modules pinned while the packet is queued. nf_trace doesn't matter anymore at this point. - when encapsulating or decapsulating IPsec packets. We want to continue tracing these packets after IPsec processing. - when passing packets through virtual network devices. Only devices on that encapsulate in IPv4/v6 matter since otherwise nf_trace is not used anymore. Its not entirely clear whether those packets should be traced after that, however we've always done that. - when passing packets through virtual network devices that make the packet cross network namespace boundaries. This is the only cases where we clearly want to reset nf_trace and is also what the original patch intended to fix. Add a new function nf_reset_trace() and use it in dev_forward_skb() to fix this properly. Signed-off-by: NPatrick McHardy <kaber@trash.net> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
