2011-03-21introduce sys_syncfs to sync a single file systemSage Weil
It is frequently useful to sync a single file system, instead of all mounted file systems via sync(2): - On machines with many mounts, it is not at all uncommon for some of them to hang (e.g. unresponsive NFS server). sync(2) will get stuck on those and may never get to the one you do care about (e.g., /). - Some applications write lots of data to the file system and then want to make sure it is flushed to disk. Calling fsync(2) on each file introduces unnecessary ordering constraints that result in a large amount of sub-optimal writeback/flush/commit behavior by the file system. There are currently two ways (that I know of) to sync a single super_block: - BLKFLSBUF ioctl on the block device: That also invalidates the bdev mapping, which isn't usually desirable, and doesn't work for non-block file systems. - 'mount -o remount,rw' will call sync_filesystem as an artifact of the current implemention. Relying on this little-known side effect for something like data safety sounds foolish. Both of these approaches require root privileges, which some applications do not have (nor should they need?) given that sync(2) is an unprivileged operation. This patch introduces a new system call syncfs(2) that takes an fd and syncs only the file system it references. Maybe someday we can $ sync /some/path and not get sync: ignoring all arguments The syscall is motivated by comments by Al and Christoph at the last LSF. syncfs(2) seems like an appropriate name given statfs(2). A similar ioctl was also proposed a while back, see http://marc.info/?l=linux-fsdevel&m=127970513829285&w=2 Signed-off-by: Sage Weil <sage@newdream.net> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2011-03-21powerpc/ptrace: Remove BUG_ON when full register set not availableMike Wolf
In some cases during a threaded core dump not all the threads will have a full register set. This happens when the signal causing the core dump races with a thread exiting. The race happens when the exiting thread has entered the kernel for the last time before the signal arrives, but doesn't get far enough through the exit code to avoid being included in the core dump. So we get a thread included in the core dump which is never going to go out to userspace again and only has a partial register set recorded Normally we would catch each thread as it is about to go into userspace and capture the full register set then. However, this exiting thread is never going to go out to userspace again, so we have no way to capture its full register set. It doesn't really matter, though, as this is a thread which is effectively already dead. So instead of hitting a BUG() in this case (a really bad choice of action in the first place), we use a poison value for the register values.

2011-03-21powerpc: Factoring mpic cpu id fetching into a functionMeador Inge
The following code snippet: unsigned int cpu = 0; if (mpic->flags & MPIC_PRIMARY) cpu = hard_smp_processor_id(); is seen in several places in the 'mpic.c' code. This changeset factors that pattern out into a helper function called 'mpic_processor_id'.

2011-03-21powerpc: Make MPIC honor the "pic-no-reset" device tree propertyMeador Inge
This property, defined in the Open PIC binding, tells the kernel not to use the reset bit in the global configuration register. Additionally, its presence mandates that only sources which are actually used (i.e. appear in the device tree) should have their VECPRI bits initialized. Although, "pic-no-reset" can be used for the same use cases that "protected-sources" is covering, the "protected-sources" implementation was left completely intact. This is a more pragmatic approach as there are already several existing systems which use protected sources. If "pic-no-reset" *and* "protected-sources" are both used, however, then "pic-no-reset" takes precedence in terms of the init behavior and the sanity checks done by protected sources will still take place.

2011-03-21powerpc/pci: Fix crash in PCI code on ppc64 when matching device nodesBenjamin Herrenschmidt
Commit b5d937de0367d26f65b9af1aef5f2c34c1939be0 has a bug which causes basically a NULL dereference in the PCI code during boot on ppc64 machines. fetch_dev_dn() is called when dev->dev.of_node is NULL, so using that as the starting point for the search makes no sense. It should instead start from the device node of the PHB. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Commit 8d7718aa082aaf30a0b4989e1f04858952f941bc changed "int" to "u32" in the prototypes but not the definition. I missed this when I saw the patch go by on LKML. We cast "u32 *" to "int *" since we are tying into the underlying atomics framework, and atomic_t uses int as its value type.

2011-03-18x86: Flush TLB if PGD entry is changed in i386 PAE modeShaohua Li
According to intel CPU manual, every time PGD entry is changed in i386 PAE mode, we need do a full TLB flush. Current code follows this and there is comment for this too in the code. But current code misses the multi-threaded case. A changed page table might be used by several CPUs, every such CPU should flush TLB. Usually this isn't a problem, because we prepopulate all PGD entries at process fork. But when the process does munmap and follows new mmap, this issue will be triggered. When it happens, some CPUs keep doing page faults: http://marc.info/?l=linux-kernel&m=129915020508238&w=2 Reported-by: Yasunori Goto<y-goto@jp.fujitsu.com> Tested-by: Yasunori Goto<y-goto@jp.fujitsu.com> Reviewed-by: Rik van Riel <riel@redhat.com> Signed-off-by: Shaohua Li<shaohua.li@intel.com> Cc: Mallick Asit K <asit.k.mallick@intel.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: linux-mm <linux-mm@kvack.org> Cc: stable <stable@kernel.org> LKML-Reference: <1300246649.2337.95.camel@sli10-conroe> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2011-03-18x86, dumpstack: Correct stack dump info when frame pointer is availableNamhyung Kim
Current stack dump code scans entire stack and check each entry contains a pointer to kernel code. If CONFIG_FRAME_POINTER=y it could mark whether the pointer is valid or not based on value of the frame pointer. Invalid entries could be preceded by '?' sign. However this was not going to happen because scan start point was always higher than the frame pointer so that they could not meet. Commit 9c0729dc8062 ("x86: Eliminate bp argument from the stack tracing routines") delayed bp acquisition point, so the bp was read in lower frame, thus all of the entries were marked invalid. This patch fixes this by reverting above commit while retaining stack_frame() helper as suggested by Frederic Weisbecker. End result looks like below: before: [ 3.508329] Call Trace: [ 3.508551] [<ffffffff814f35c9>] ? panic+0x91/0x199 [ 3.508662] [<ffffffff814f3739>] ? printk+0x68/0x6a [ 3.508770] [<ffffffff81a981b2>] ? mount_block_root+0x257/0x26e [ 3.508876] [<ffffffff81a9821f>] ? mount_root+0x56/0x5a [ 3.508975] [<ffffffff81a98393>] ? prepare_namespace+0x170/0x1a9 [ 3.509216] [<ffffffff81a9772b>] ? kernel_init+0x1d2/0x1e2 [ 3.509335] [<ffffffff81003894>] ? kernel_thread_helper+0x4/0x10 [ 3.509442] [<ffffffff814f6880>] ? restore_args+0x0/0x30 [ 3.509542] [<ffffffff81a97559>] ? kernel_init+0x0/0x1e2 [ 3.509641] [<ffffffff81003890>] ? kernel_thread_helper+0x0/0x10 after: [ 3.522991] Call Trace: [ 3.523351] [<ffffffff814f35b9>] panic+0x91/0x199 [ 3.523468] [<ffffffff814f3729>] ? printk+0x68/0x6a [ 3.523576] [<ffffffff81a981b2>] mount_block_root+0x257/0x26e [ 3.523681] [<ffffffff81a9821f>] mount_root+0x56/0x5a [ 3.523780] [<ffffffff81a98393>] prepare_namespace+0x170/0x1a9 [ 3.523885] [<ffffffff81a9772b>] kernel_init+0x1d2/0x1e2 [ 3.523987] [<ffffffff81003894>] kernel_thread_helper+0x4/0x10 [ 3.524228] [<ffffffff814f6880>] ? restore_args+0x0/0x30 [ 3.524345] [<ffffffff81a97559>] ? kernel_init+0x0/0x1e2 [ 3.524445] [<ffffffff81003890>] ? kernel_thread_helper+0x0/0x10 -v5: * fix build breakage with oprofile -v4: * use 0 instead of regs->bp * separate out printk changes -v3: * apply comment from Frederic * add a couple of printk fixes Signed-off-by: Namhyung Kim <namhyung@gmail.com> Acked-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Soren Sandmann <ssp@redhat.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Robert Richter <robert.richter@amd.com> LKML-Reference: <1300416006-3163-1-git-send-email-namhyung@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2011-03-18Blackfin: punt unused HDMA masksMike Frysinger
No code uses these, and the short define names are polluting the global namespace where they collide with things like common irq files. So just punt the damned things. If in the future we need HDMA support, we can make a standalone header for these things. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
