2012-07-20staging: csr: remove CsrPmemAllocGreg Kroah-Hartman
It's just a wrapper around kmalloc(, GFP_KERNEL) + a call to panic() if we are out of memory, which is a very foolish thing to do (the panic that is.) So replace it with calls to kmalloc() and ignore the out-of-memory casese for now, odds are it will not be hit, and if it does, hey, we will end up panicing just the same as with the old code.

2012-07-20x86, efi: Handover ProtocolMatt Fleming
As things currently stand, traditional EFI boot loaders and the EFI boot stub are carrying essentially the same initialisation code required to setup an EFI machine for booting a kernel. There's really no need to have this code in two places and the hope is that, with this new protocol, initialisation and booting of the kernel can be left solely to the kernel's EFI boot stub. The responsibilities of the boot loader then become, o Loading the kernel image from boot media File system code still needs to be carried by boot loaders for the scenario where the kernel and initrd files reside on a file system that the EFI firmware doesn't natively understand, such as ext4, etc. o Providing a user interface Boot loaders still need to display any menus/interfaces, for example to allow the user to select from a list of kernels. Bump the boot protocol number because we added the 'handover_offset' field to indicate the location of the handover protocol entry point. Cc: H.

2012-07-20ipv4: Fix neigh lookup keying over loopback/point-to-point devices.David S. Miller
We were using a special key "0" for all loopback and point-to-point device neigh lookups under ipv4, but we wouldn't use that special key for the neigh creation. So basically we'd make a new neigh at each and every lookup :-) This special case to use only one neigh for these device types is of dubious value, so just remove it entirely.

2012-07-20openvswitch: Check gso_type for correct sk_buff in queue_gso_packets().Ben Pfaff
At the point where it was used, skb_shinfo(skb)->gso_type referred to a post-GSO sk_buff. Thus, it would always be 0. We want to know the pre-GSO gso_type, so we need to obtain it before segmenting. Before this change, the kernel would pass inconsistent data to userspace: packets for UDP fragments with nonzero offset would be passed along with flow keys that indicate a zero offset (that is, the flow key for "later" fragments claimed to be "first" fragments). This inconsistency tended to confuse Open vSwitch userspace, causing it to log messages about "failed to flow_del" the flows with "later" fragments.

2012-07-20Documentation: Add newline at end-of-file to files lacking oneJesper Juhl
This patch simply adds a newline character at end-of-file to those files in Documentation/ that currently lack one. This is done for a few different reasons: A) It's rather annoying when you do "cat some_file.txt" that your prompt/cursor ends up at the end of the last line of output rather than on a new line. B) Some tools that process files line-by-line may get confused by the lack of a newline on the last line. C) The "\ No newline at end of file" line in diffs annoys me for some reason.

2012-07-20ipv4: Kill rt->fiDavid S. Miller
It's not really needed. We only grabbed a reference to the fib_info for the sake of fib_info local metrics. However, fib_info objects are freed using RCU, as are therefore their private metrics (if any). We would have triggered a route cache flush if we eliminated a reference to a fib_info object in the routing tables. Therefore, any existing cached routes will first check and see that they have been invalidated before an errant reference to these metric values would occur. Signed-off-by: David S.

2012-07-20ipv4: Cache input routes in fib_info nexthops.David S. Miller
Caching input routes is slightly simpler than output routes, since we don't need to be concerned with nexthop exceptions. (locally destined, and routed packets, never trigger PMTU events or redirects that will be processed by us). However, we have to elide caching for the DIRECTSRC and non-zero itag cases.

2012-07-20ipv4: Cache output routes in fib_info nexthops.David S. Miller
If we have an output route that lacks nexthop exceptions, we can cache it in the FIB info nexthop. Such routes will have DST_HOST cleared because such routes refer to a family of destinations, rather than just one. The sequence of the handling of exceptions during route lookup is adjusted to make the logic work properly. Before we allocate the route, we lookup the exception. Then we know if we will cache this route or not, and therefore whether DST_HOST should be set on the allocated route. Then we use DST_HOST to key off whether we should store the resulting route, during rt_set_nexthop(), in the FIB nexthop cache. With help from Eric Dumazet. Signed-off-by: David S. Miller <davem@davemloft.net>
