2013-07-11ipv6: fix route selection if kernel is not compiled with CONFIG_IPV6_ROUTER_PREFHannes Frederic Sowa
This is a follow-up patch to 3630d40067a21d4dfbadc6002bb469ce26ac5d52 ("ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available"). Since the removal of rt->n in rt6_info we can end up with a dst == NULL in rt6_check_neigh. In case the kernel is not compiled with CONFIG_IPV6_ROUTER_PREF we should also select a route with unkown NUD state but we must not avoid doing round robin selection on routes with the same target. So introduce and pass down a boolean ``do_rr'' to indicate when we should update rt->rr_ptr. As soon as no route is valid we do backtracking and do a lookup on a higher level in the fib trie. v2: a) Improved rt6_check_neigh logic (no need to create neighbour there) and documented return values. v3: a) Introduce enum rt6_nud_state to get rid of the magic numbers (thanks to David Miller). b) Update and shorten commit message a bit to actualy reflect the source.

2013-07-11vxlan: Fix kernel crash on rmmod.Pravin B Shelar
vxlan exit module unregisters vxlan net and then it unregisters rtnl ops which triggers vxlan_dellink() from __rtnl_kill_links(). vxlan_dellink() deletes vxlan-dev from vxlan_list which has list-head in vxlan-net-struct but that is already gone due to net-unregister. That is how we are getting following crash. Following commit fixes the crash by fixing module exit path.

2013-07-11drm/i915: fix up readout of the lvds dither bit on gen2/3Daniel Vetter
It's in the PFIT_CONTROL register, but very much associated with the lvds encoder. So move the readout for it (in the case of an otherwise disabled pfit) from the pipe to the lvds encoder's get_config function. Otherwise we get a pipe state mismatch if we use pipe B for a non-lvds output and we've left the dither bit enabled behind us. This can happen if the BIOS has set the bit (some seem to unconditionally do that, even in the complete absence of an lvds port), but not enabled pipe B at boot-up. Then we won't clear the pfit control register since we can only touch that if the pfit is associated with our pipe in the crtc configuration - we could trample over the pfit state of the other pipe otherwise since it's shared. Once pipe B is enabled we notice that the 6to8 dither bit is set and complain about the mismatch. Note that testing indicates that we don't actually need to set this bit when the pfit is disabled, dithering on 18bpp panels seems to work regardless. But ripping that code out is not something for a bugfix meant for -rc kernels. v2: While at it clarify the logic in i9xx_get_pfit_config, spurred by comments from Chris on irc. v3: Use Chris suggestion to make the control flow in i9xx_get_pfit_config easier to understand. v4: Kill the extra line, spotted by Chris.

As for new features, there were a few, but nothing to write to LWN about. These include: New function trigger called "dump" and "cpudump" that will cause ftrace to dump its buffer to the console when the function is called. The difference between "dump" and "cpudump" is that "dump" will dump the entire contents of the ftrace buffer, where as "cpudump" will only dump the contents of the ftrace buffer for the CPU that called the function. Another small enhancement is a new sysctl switch called "traceoff_on_warning" which, when enabled, will disable tracing if any WARN_ON() is triggered.

2013-07-11spi: revert master->setup function removal for altera and nuc900Stephen Warren
Commit 24778be "spi: convert drivers to use bits_per_word_mask" removed what appeared to be redundant code from many drivers. However, it appears that in the spi-bitbang case, these functions are required by the spi-bitbang core, even if they don't do anything. Restore them. For 3.12, the spi-bitbang core should be adjusted not to require these callbacks to exist if they don't need to do anything. This is the equivalent of Michal Simek's patch "spi/xilinx: Revert master->setup function removal", applied to other affected drivers.

2013-07-10Revert "Makefile: Fix install error with make -j option"Linus Torvalds
This reverts commit d2aae8477cd00325bb7c7c7e95be488088900c48. It is completely and utterly broken. Module install should not build any files, and adding broken dependencies to "help" it build files is complete and utter sh*t. The kernel should not be built by root, and "make install" and "make module_install" (that for obvious reasons need to be run as root) absolutely must not build any files. They should only ever copy the already-built files over. So having dependencies for the install targets is wrong, wrong, wrong. If you try to install a kernel without building it first, you *should* get errors. The build system shouldn't try to help root build the files.

Userspace may produce vectors greater than MAX_SKB_FRAGS. When we try to linearize parts of the skb to let the rest of iov to be fit in the frags, we need count copylen into linear when calling macvtap_alloc_skb() instead of partly counting it into data_len.

2013-07-10ext4: fix warning in ext4_evict_inode()Jan Kara
The following race can lead to ext4_evict_inode() seeing i_ioend_count > 0 and thus triggering a sanity check warning: CPU1 CPU2 ext4_end_bio() ext4_evict_inode() ext4_finish_bio() end_page_writeback(); truncate_inode_pages() evict page WARN_ON(i_ioend_count > 0); ext4_put_io_end_defer() ext4_release_io_end() dec i_ioend_count This is possible use-after-free bug since we decrement i_ioend_count in possibly released inode. Since i_ioend_count is used only for sanity checks one possible solution would be to just remove it but for now I'd like to keep those sanity checks to help debugging the new ext4 writeback code. This patch changes ext4_end_bio() to call ext4_put_io_end_defer() before ext4_finish_bio() in the shortcut case when unwritten extent conversion isn't needed. In that case we don't need the io_end so we are safe to drop it early.

2013-07-10zswap: add to mm/Seth Jennings
zswap is a thin backend for frontswap that takes pages that are in the process of being swapped out and attempts to compress them and store them in a RAM-based memory pool. This can result in a significant I/O reduction on the swap device and, in the case where decompressing from RAM is faster than reading from the swap device, can also improve workload performance. It also has support for evicting swap pages that are currently compressed in zswap to the swap device on an LRU(ish) basis. This functionality makes zswap a true cache in that, once the cache is full, the oldest pages can be moved out of zswap to the swap device so newer pages can be compressed and stored in zswap.

2013-07-10zbud: add to mm/Seth Jennings
zbud is an special purpose allocator for storing compressed pages. It is designed to store up to two compressed pages per physical page. While this design limits storage density, it has simple and deterministic reclaim properties that make it preferable to a higher density approach when reclaim will be used. zbud works by storing compressed pages, or "zpages", together in pairs in a single memory page called a "zbud page". The first buddy is "left justifed" at the beginning of the zbud page, and the last buddy is "right justified" at the end of the zbud page. The benefit is that if either buddy is freed, the freed buddy space, coalesced with whatever slack space that existed between the buddies, results in the largest possible free region within the zbud page. zbud also provides an attractive lower bound on density. The ratio of zpages to zbud pages can not be less than 1. This ensures that zbud can never "do harm" by using more pages to store zpages than the uncompressed zpages would have used on their own. This implementation is a rewrite of the zbud allocator internally used by zcache in the driver/staging tree. The rewrite was necessary to remove some of the zcache specific elements that were ingrained throughout and provide a generic allocation interface that can later be used by zsmalloc and others. This patch adds zbud to mm/ for later use by zswap.
