There is no point having the NET dependency on the select target, as it forces all users to depend on NET to tell they support BPF_JIT. Move the config option to the bottom of the file - this could be a nice place also for future "selectable" config symbols. Fix up all users to drop the dependency on NET now that it is not required to supress warnings for non-NET builds.

Pull sparc updates from David Miller: 1) Kill off support for sun4c and Cypress sun4m chips. And as a result we were able to also kill off that ugly btfixup thing that required multi-stage links of the final vmlinux image in the Kbuild system. This should make the kbuild maintainers really happy. Thanks a lot to Sam Ravnborg for his tireless efforts to get this going. 2) Convert sparc64 to nobootmem. I suspect now with sparc32 being a lot cleaner, it should be able to fall in line and modernize in this area too. 3) Make sparc32 use generic clockevents, from Tkhai Kirill. [ I fixed up the BPF rules, and tried to clean up the build rules too. But I don't have - or want - a sparc cross-build environment, so the BPF rule bug and the related build cleanup was all done with just a bare "make -n" pseudo-test. - Linus ] * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next: (110 commits) sparc32: use flushi when run-time patching in per_cpu_patch sparc32: fix cpuid_patch run-time patching sparc32: drop unused inline functions in srmmu.c sparc32: drop unused functions in pgtsrmmu.h sparc32,leon: move leon mmu functions to leon_mm.c sparc32,leon: remove duplicate definitions in leon.h sparc32,leon: remove duplicate UART register definitions sparc32,leon: move leon ASI definitions to asi.h sparc32: move trap table to a separate file sparc64: renamed ttable.S to ttable_64.S sparc32: Remove asm/sysen.h header. sparc32: Delete asm/smpprim.h sparc32: Remove unused empty_bad_page{,_table} declarations. sparc32: Kill boot_cpu_id4 sparc32: Move GET_PROCESSOR*_ID() out of asm/asmmacro.h sparc32: Remove completely unused code from asm/cache.h sparc32: Add ucmpdi2.o to obj-y instead of lib-y. sparc32: add ucmpdi2 sparc: introduce arch/sparc/Kbuild sparc: remove obsolete documentation ...

Pull networking changes from David Miller: 1) Get rid of the error prone NLA_PUT*() macros that used an embedded goto. 2) Kill off the token-ring and MCA networking drivers, from Paul Gortmaker. 3) Reduce high-order allocations made by datagram AF_UNIX sockets, from Eric Dumazet. 4) Add PTP hardware clock support to IGB and IXGBE, from Richard Cochran and Jacob Keller. 5) Allow users to query timestamping capabilities of a card via ethtool, from Richard Cochran. 6) Add loadbalance mode to the teaming driver, from Jiri Pirko. Part of this is that we can now have BPF filters not attached to sockets, and the loadbalancing function is calculated using one. 7) Francois Romieu went through the network drivers removing gratuitous uses of netdev->base_addr, perhaps some day we can remove it completely but it's used for ISA probing still. 8) Add a BPF JIT for sparc. I know, who cares, right? :-) 9) Move networking sysctl registry away from using the compatability mode interfaces in the sysctl code. From Eric W Biederman. 10) Pavel Emelyanov added a way to save and restore TCP socket state via TCP_REPAIR, TCP_REPAIR_QUEUE, and TCP_QUEUE_SEQ socket options as well as a way to forcefully bind a socket to a port via the sk->sk_reuse value SK_FORCE_REUSE. There is also a TCP_REPAIR_OPTIONS which allows to reinstante the TCP options enabled on the connection. 11) Several enhancements from Eric Dumazet that, in particular, can enhance splice performance on TCP sockets significantly. a) Reset the offset of the per-socket sendmsg page when we know we're the only use of the page in linear_to_page(). b) Add facilities such that skb->data can be backed a page rather than SLAB kmalloc'd memory. In particular devices which were receiving into linear RX buffers can now end up providing paged data. The big result is that code like splice and GRO do not have to copy any more. 12) Allow a pure sender to more gracefully handle ACK backlogs in TCP. What can happen at high rates is that the sender hasn't grown his receive buffer limits at all (he's not receiving data so really doesn't need to), but the non-data ACKs consume receive buffer space. sk_add_backlog() is too aggressive in dropping frames in this case, so relax it's requirements by using the receive buffer plus the send buffer limit as the backlog limit instead of just the former. Also from Eric Dumazet. 13) Add ipv6 support to L2TP, from Benjamin LaHaise, James Chapman, and Chris Elston. 14) Implement TCP early retransmit (RFC 5827), from Yuchung Cheng. Basically, we can start fast retransmit before hiting the dupack threshold under certain conditions. 15) New CODEL active queue management packet scheduler, from Eric Dumazet based upon initial work by Dave Taht. Basically, the big feature is that packets are dropped (or ECN bits are set) based upon how long packets live in the queue, rather than the queue length (which is what RED uses). * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1341 commits) drivers/net/stmmac: seq_file fix memory leak ipv6/exthdrs: strict Pad1 and PadN check USB: qmi_wwan: Add ZTE (Vodafone) K3520-Z USB: qmi_wwan: Add ZTE (Vodafone) K3765-Z USB: qmi_wwan: Make forced int 4 whitelist generic net/ipv4: replace simple_strtoul with kstrtoul net/ipv4/ipconfig: neaten __setup placement net: qmi_wwan: Add Vodafone/Huawei K5005 support net: cdc_ether: Add ZTE WWAN matches before generic Ethernet ipv6: use skb coalescing in reassembly ipv4: use skb coalescing in defragmentation net: introduce skb_try_coalesce() net:ipv6:fixed space issues relating to operators. net:ipv6:fixed a trailing white space issue. ipv6: disable GSO on sockets hitting dst_allfrag tg3: use netdev_alloc_frag() API net: napi_frags_skb() is static ppp: avoid false drop_monitor false positives ipv6: bool/const conversions phase2 ipx: Remove spurious NULL checking in ipx_ioctl(). ...

This branch simplifies and clarifies the dcache lookup, and allows us to do certain nice optimizations when comparing dentries. It also cleans up the interface to __d_lookup_rcu(), especially around passing the inode information around. * dentry-cleanups: vfs: make it possible to access the dentry hash/len as one 64-bit entry vfs: move dentry name length comparison from dentry_cmp() into callers vfs: do the careful dentry name access for all dentry_cmp cases vfs: remove unnecessary d_unhashed() check from __d_lookup_rcu vfs: clean up __d_lookup_rcu() and dentry_cmp() interfaces

This teaches vfs_fstat() to use the appropriate f[get|put]_light functions, allowing it to avoid some unnecessary locking for the common case. More noticeably, it also cleans up and simplifies the "getname_flags()" function, which now relies on the architecture strncpy_from_user() doing all the user access checks properly, instead of hacking around the fact that on x86 it didn't use to do it right (see commit 92ae03f2: "x86: merge 32/64-bit versions of 'strncpy_from_user()' and speed it up"). * vfs-cleanups: VFS: make vfs_fstat() use f[get|put]_light() VFS: clean up and simplify getname_flags() x86: make word-at-a-time strncpy_from_user clear bytes at the end

This makes cp_new_stat() a bit more readable, and avoids having to memset() the whole structure just to fill in a couple of padding fields. This is another result of me looking at code generation of functions that show up high on certain kernel profiles, and just going "Oh, let's just clean that up". Architectures that don't supply the #define to fill just the padding fields will still fall back to memset(). * stat-cleanups: vfs: don't force a big memset of stat data just to clear padding fields vfs: de-crapify "cp_new_stat()" function

This series sanitizes the interface to unmap_vma(). The crazy interface annoyed me no end when I was looking at unmap_single_vma(), which we can spend quite a lot of time in (especially with loads that have a lot of small fork/exec's: shell scripts etc). Moving the nr_accounted calculations to where they belong at least clarifies things a little. I hope to come back to look at the performance of this later, but if/when I get back to it I at least don't have to see the crazy interfaces any more. * vm-cleanups: vm: remove 'nr_accounted' calculations from the unmap_vmas() interfaces vm: simplify unmap_vmas() calling convention
