Commit 16559ae4 ("kgdb: remove #include <linux/serial_8250.h> from kgdb.h") changes the kgdb.h file so that drivers including it do not implicitly include linux/platform_device.h. The mmp framebuffer driver is new, so Greg did not have a chance to fix it up when introducing his change. Signed-off-by:

Add mmp display subsystem to support Marvell MMP display controllers. This subsystem contains 4 parts: --fb folder --core.c --hw folder --panel folder 1. fb folder contains implementation of fb. fb get path and overlay from common interface and operates on these structures. 2. core.c provides common interface for a hardware abstraction. Major parts of this interface are: a) Path: path is a output device connected to a panel or HDMI TV. Main operations of the path is set/get timing/output color. fb operates output device through path structure. b) Ovly: Ovly is a buffer shown on the path. Ovly describes frame buffer and its source/destination size, offset, input color, buffer address, z-order, and so on. Each fb device maps to one overlay. 3. hw folder contains implementation of hardware operations defined by core.c. It registers paths for fb use. 4. panel folder contains implementation of panels. It's connected to path. Panel drivers would also regiester panels and linked to path when probe. Signed-off-by: -

Framebuffer support for the Goldfish emulator. This takes the Google emulator and applies the x86 cleanups as well as moving the blank methods to the usual Linux place and dropping the Android early suspend logic (for now at least, that can be looked at as Android and upstream converge). Dropped various oddities like setting MTRRs on a virtual frame buffer emulation... With the drivers so far you can now boot a Linux initrd and have fun.

Move the device rebind procedures for cardbus devices from the pm.resume into the pm.complete callback. The reason for moving the code is: "[...] The PM code needs to send suspend and resume messages to every device in the right order, and it can't do that if new devices are being added at the same time. [...]" However the situation really isn't quite that rigid. In particular, adding new children during a resume callback shouldn't cause much of problem because the children don't need to be resumed anyway (since they were never suspended). On the other hand, if you do it you will get a dev_warn() from the PM core, something like 'parent should not be sleeping'. Still, it is considered bad form and should be avoided if possible."

On cris-linux-gcc, __SIZE_TYPE__ expands to "unsigned int", as gcc-4.6.3-nolibc/cris-linux/lib/gcc/cris-linux/4.6.3/plugin/include/config/cris/linux.h has #define SIZE_TYPE "unsigned int" Hence __kernel_size_t is also "unsigned int". But __kernel_ssize_t is "long", which has a different base type, causing compiler warnings like: fs/quota/quota_tree.c:372:4: warning: format '%zd' expects argument of type 'signed size_t', but argument 4 has type 'ssize_t' [-Wformat] To fix this, __kernel_ssize_t should be changed to "int". Hence cris can just use the generic 32-bit versions from include/asm-generic/posix_types.h for all size-related types.

We found that bdev->bd_invalidated was left set once revalidate_disk() is called, which results in page cache flush every time that device is open. Specifically, we found this problem in MD block device. Once we resize a MD device, mdadm --monitor periodically flush all page cache for that device every 60 or 1000 seconds when it opens the device. This bug lies since at least 3.2.0 till the latest kernel(3.6.2). Patch is attached. The following steps will reproduce the problem. 1. prepair a block device (eg /dev/sdb). 2. create two partitions: sudo parted /dev/sdb mklabel gpt mkpart primary 0% 50% mkpart primary 50% 100% 3. create a md device. sudo mdadm -C /dev/md/hoge -l 1 -n 2 -e 1.2 --assume-clean --auto=md --symlink=no /dev/sdb1 /dev/sdb2 4. create file system and mount it sudo mkfs.ext3 /dev/md/hoge sudo mkdir /mnt/test sudo mount /dev/md/hoge /mnt/test 5. try to resize the device sudo mdadm -G /dev/md/hoge --size=max 6. create a file to fill file cache. sudo dd if=/dev/urandom of=/mnt/test/data bs=1M count=10 and verify the current status of file by free command. 7. mdadm monitor will open the md device every 1000 seconds and you will find all file cache on the device are cleared. The timing can be reduced by the following steps. a) kill mdadm and restart it with --delay option /sbin/mdadm --monitor --delay=30 --pid-file /var/run/mdadm/monitor.pid --daemonise --scan --syslog or open the md device directly. sudo dd if=/dev/md/hoge of=/dev/null bs=4096 count=1 Signed-off-by:

Running the command: inotifywait -e unmount /mnt/disk immediately aborts with a -EINVAL return code. This is however a valid parameter. This abort occurs only if unmount is the sole event parameter. If other event parameters are supplied, then the unmount event wait will work. The problem was introduced by commit 44b350fc ("inotify: Fix mask checks"). In that commit, it states: The mask checks in inotify_update_existing_watch() and inotify_new_watch() are useless because inotify_arg_to_mask() sets FS_IN_IGNORED and FS_EVENT_ON_CHILD bits anyway. But instead of removing the useless checks, it did this: mask = inotify_arg_to_mask(arg); - if (unlikely(!mask)) + if (unlikely(!(mask & IN_ALL_EVENTS))) return -EINVAL; The problem is that IN_ALL_EVENTS doesn't include IN_UNMOUNT, and other parts of the code keep IN_UNMOUNT separate from IN_ALL_EVENTS. So the check should be: if (unlikely(!(mask & (IN_ALL_EVENTS | IN_UNMOUNT)))) But inotify_arg_to_mask(arg) always sets the IN_UNMOUNT bit in the mask anyway, so the check is always going to pass and thus should simply be removed. Also note that inotify_arg_to_mask completely controls what mask bits get set from arg, there's no way for invalid bits to get enabled there. Lets fix it by simply removing the useless broken checks.

Introduce compiletime_assert to compiler.h, which moves the details of how to break a build and emit an error message for a specific compiler to the headers where these details should be. Following in the tradition of the POSIX assert macro, compiletime_assert creates a build-time error when the supplied condition is *false*. Next, we add BUILD_BUG_ON_MSG to bug.h which simply wraps compiletime_assert, inverting the logic, so that it fails when the condition is *true*, consistent with the language "build bug on." This macro allows you to specify the error message you want emitted when the supplied condition is true. Finally, we remove all other code from bug.h that mucks with these details (BUILD_BUG & BUILD_BUG_ON), and have them all call BUILD_BUG_ON_MSG. This not only reduces source code bloat, but also prevents the possibility of code being changed for one macro and not for the other (which was previously the case for BUILD_BUG and BUILD_BUG_ON). Since __compiletime_error_fallback is now only used in compiler.h, I'm considering it a private macro and removing the double negation that's now extraneous.

Prior to the introduction of __attribute__((error("msg"))) in gcc 4.3, creating compile-time errors required a little trickery. BUILD_BUG{,_ON} uses this attribute when available to generate compile-time errors, but also uses the negative-sized array trick for older compilers, resulting in two error messages in some cases. The reason it's "some" cases is that as of gcc 4.4, the negative-sized array will not create an error in some situations, like inline functions. This patch replaces the negative-sized array code with the new __compiletime_error_fallback() macro which expands to the same thing unless the the error attribute is available, in which case it expands to do{}while(0), resulting in exactly one compile-time error on all versions of gcc. Note that we are not changing the negative-sized array code for the unoptimized version of BUILD_BUG_ON, since it has the potential to catch problems that would be disabled in later versions of gcc were __compiletime_error_fallback used. The reason is that that an unoptimized build can't always remove calls to an error-attributed function call (like we are using) that should effectively become dead code if it were optimized. However, using a negative-sized array with a similar value will not result in an false-positive (error). The only caveat being that it will also fail to catch valid conditions, which we should be expecting in an unoptimized build anyway. Signed-off-by: -

Negative sized arrays wont create a compile-time error in some cases starting with gcc 4.4 (e.g., inlined functions), but gcc 4.3 introduced the error function attribute that will. This patch modifies BUILD_BUG_ON to behave like BUILD_BUG already does, using the error function attribute so that you don't have to build the entire kernel to discover that you have a problem, and then enjoy trying to track it down from a link-time error. Also, we are only including asm/bug.h and then expecting that linux/compiler.h will eventually be included to define __linktime_error (used in BUILD_BUG_ON). This patch includes it directly for clarity and to avoid the possibility of changes in <arch>/*/include/asm/bug.h being changed or not including linux/compiler.h for some reason. Signed-off-by:

When __CHECKER__ is defined, we disable all of the BUILD_BUG.* macros. However, both BUILD_BUG_ON_NOT_POWER_OF_2 and BUILD_BUG_ON was evaluating to nothing in this case, and we want (0) since this is a function-like macro that will be followed by a semicolon. Signed-off-by:

__linktime_error() does the same thing as __compiletime_error() and is only used in bug.h. Since the macro defines a function attribute that will cause a failure at compile-time (not link-time), it makes more sense to keep __compiletime_error(), which is also neatly mated with __compiletime_warning().

Using GCC_VERSION reduces complexity, is easier to read and is GCC's recommended mechanism for doing version checks. (Just don't ask me why they didn't define it in the first place.) This also makes it easy to merge compiler-gcc{,3,4}.h should somebody want to. Signed-off-by: -
Daniel Santos authored
Throughout compiler*.h, many version checks are made. These can be simplified by using the macro that gcc's documentation recommends. However, my primary reason for adding this is that I need bug-check macros that are enabled at certain gcc versions and it's cleaner to use this macro than the tradition method: #if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ => 2) If you add patch level, it gets this ugly: #if __GNUC__ > 4 || (__GNUC__ == 4 && (__GNUC_MINOR__ > 2 || \ __GNUC_MINOR__ == 2 __GNUC_PATCHLEVEL__ >= 1)) As opposed to: #if GCC_VERSION >= 40201 While having separate headers for gcc 3 & 4 eliminates some of this verbosity, they can still be cleaned up by this.

There are some clean ups relating to the transaction code and the shrinker, which are mostly in preparation for further development, but also make the code much easier to follow in these areas. There is a patch which allows the use of ->writepages even in the default ordered write mode for all writebacks. This results in sending larger i/os to the block layer, and a subsequent increase in performance. It also reduces the number of different i/o paths by one.

A patch to fix some unreachable code in search_my_process_keyrings() got applied twice by two different routes upstream as commits e67eab39 and b010520a (both "fix unreachable code"). Unfortunately, the second application removed something it shouldn't have and this wasn't detected by GIT. This is due to the patch not having sufficient lines of context to distinguish the two places of application. The effect of this is relatively minor: inside the kernel, the keyring search routines may search multiple keyrings and then prioritise the errors if no keys or negative keys are found in any of them. With the extra deletion, the presence of a negative key in the thread keyring (causing ENOKEY) is incorrectly overridden by an error searching the process keyring. So revert the second application of the patch. Signed-off-by:

Pull networking update from David Miller: 1) Checkpoint/restarted TCP sockets now can properly propagate the TCP timestamp offset. From Andrey Vagin. 2) VMWARE VM VSOCK layer, from Andy King. 3) Much improved support for virtual functions and SR-IOV in bnx2x, from Ariel ELior. 4) All protocols on ipv4 and ipv6 are now network namespace aware, and all the compatability checks for initial-namespace-only protocols is removed. Thanks to Tom Parkin for helping deal with the last major holdout, L2TP. 5) IPV6 support in netpoll and network namespace support in pktgen, from Cong Wang. 6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration Protocol (MVRP) support, from David Ward. 7) Compute packet lengths more accurately in the packet scheduler, from Eric Dumazet. 8) Use per-task page fragment allocator in skb_append_datato_frags(), also from Eric Dumazet. 9) Add support for connection tracking labels in netfilter, from Florian Westphal. 10) Fix default multicast group joining on ipv6, and add anti-spoofing checks to 6to4 and 6rd. From Hannes Frederic Sowa. 11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern times, rearrange inet frag datastructures for better cacheline locality, and move more operations outside of locking. From Jesper Dangaard Brouer. 12) Instead of strict master <--> slave relationships, allow arbitrary scenerios with "upper device lists". From Jiri Pirko. 13) Improve rate limiting accuracy in TBF and act_police, also from Jiri Pirko. 14) Add a BPF filter netfilter match target, from Willem de Bruijn. 15) Orphan and delete a bunch of pre-historic networking drivers from Paul Gortmaker. 16) Add TSO support for GRE tunnels, from Pravin B SHelar. Although this still needs some minor bug fixing before it's %100 correct in all cases. 17) Handle unresolved IPSEC states like ARP, with a resolution packet queue. From Steffen Klassert. 18) Remove TCP Appropriate Byte Count support (ABC), from Stephen Hemminger. This was long overdue. 19) Support SO_REUSEPORT, from Tom Herbert. 20) Allow locking a socket BPF filter, so that it cannot change after a process drops capabilities. 21) Add VLAN filtering to bridge, from Vlad Yasevich. 22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in the ipv6 routes, from YOSHIFUJI Hideaki. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1538 commits) ipv6: fix race condition regarding dst->expires and dst->from. net: fix a wrong assignment in skb_split() ip_gre: remove an extra dst_release() ppp: set qdisc_tx_busylock to avoid LOCKDEP splat atl1c: restore buffer state net: fix a build failure when !CONFIG_PROC_FS net: ipv4: fix waring -Wunused-variable net: proc: fix build failed when procfs is not configured Revert "xen: netback: remove redundant xenvif_put" net: move procfs code to net/core/net-procfs.c qmi_wwan, cdc-ether: add ADU960S bonding: set sysfs device_type to 'bond' bonding: fix bond_release_all inconsistencies b44: use netdev_alloc_skb_ip_align() xen: netback: remove redundant xenvif_put net: fec: Do a sanity check on the gpio number ip_gre: propogate target device GSO capability to the tunnel device ip_gre: allow CSUM capable devices to handle packets bonding: Fix initialize after use for 3ad machine state spinlock bonding: Fix race condition between bond_enslave() and bond_3ad_update_lacp_rate() ...

Introduce a common smp_callin() function to call from trampoline_32.S. Add platform specific functions to handle the platform details. This is in preparation for a patch that will unify the smp boot stuff for all architectures. sparc32 was significantly different to warrant this patch in preparation. Signed-off-by:
