This version brings a some new tests, and a host of changes to fix false positives, of particular note: - detect 'var ++;' and 'var --;' as a bad combination - multistatement #defines are now checked based on statement count - multistatement #defines with initialisation correctly reported - checks the location of the inline keywords - EXPORT_SYMBOL for variables are now understood - typedefs are loosened to handle sparse etc This version of checkpatch.pl can be found at the following URL: http://www.shadowen.org/~apw/public/checkpatch/checkpatch.pl-0.05 Full Changelog: Andy Whitcroft (18): Version: 0.05 macro definition checks should be for a single statement avoid assignements only in if conditionals declarations of function pointers need no space multiline macros which are purely initialisation cannot be wrapped EXPORT_SYMBOL can also directly follow a variable definition check on the location of the inline keyword EXPORT_SYMBOL needs to allow for attributes ensure we do not find C99 // in strings handle malformed #include lines accept the {0,} form typedefs are sensible for defining function pointer parameters ensure { handling correctly handles nested switch() statements trailing whitespace checks are not anchored typedefs for sparse bitwise annotations make sense update the type matcher to include sparse annotations clean up indent and spacing Signed-off-by: Andy Whitcroft <apw@shadowen.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The intervals of domains that do not have SD_BALANCE_NEWIDLE must be considered for the calculation of the time of the next balance. Otherwise we may defer rebalancing forever. Siddha also spotted that the conversion of the balance interval to jiffies is missing. Fix that to. From: Srivatsa Vaddagiri <vatsa@linux.vnet.ibm.com> also continue the loop if !(sd->flags & SD_LOAD_BALANCE). Tested-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> It did in fact trigger under all three of mainline, CFS, and -rt including CFS -- see below for a couple of emails from last Friday giving results for these three on the AMD box (where it happened) and on a single-quad NUMA-Q system (where it did not, at least not with such severity).

Egmont Koblinger authored
Recently my console UTF-8 patch went mainline. Here is an additional patch that fixes two nasty issues and improves a third one, namely: 1. My patch changed the behavior if a glyph is not found in the Unicode mapping table. Previously for Unicode values less than 256 or 512 the kernel tried to display the glyph from that position of the glyph table, which could lead to a different accented letter being displayed. I removed this fallback possibility and changed it to display the replacement symbol. As Behdad pointed out, some fonts (e.g. sun12x22 from the kbd package) lack Unicode mapping information, hence all you get is lots of question marks. Though theoretically it's actually a user-space bug (the font should be fixed), Behdad and I both believe that it'd be good to work around in the kernel by re-introducing the fallback solution for ASCII characters only. This sounds a quite reasonable decision, since all fonts ship the ASCII characters in the first 128 positions. This way users won't be surprised by lots of question marks just because s/he issued a not-so-perfectly parameterized setfont command. As this fallback is only re-introduced for code points below 128, you still won't see an accented letter replaced by another, but at least you'll always get the English letters right. 2. My patch introduced "question mark with inverted color attributes" as a last resort fallback glyph. Though it perfectly works on VGA console, on framebuffer you may end up with question marks that are highlighed but shouldn't be, and normal characters that are accidentally highlighed. This is caused by missing FLUSHes when changing the color attribute. 3. I've updated the table of double-width character based on Markus's updated version. Only ten new code poings (one interval) is added.

Always disable/enable interrupts in the acpi idle routine, even in the error path. This is required as the 2.6.20 change in git commit d331e739... "Fix interrupt race in idle callback" expects the idle handler to enable interrupt before returning. There was a case in acpi idle routine, in which interrupt was not being enabled before return, which caused the system to hang at bootup, while enabling C-states on an SMP system. The signature of the hang was that "processor.nocst" was required to enable boot. Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

If (start + size) is not cacheline aligned and (start & mask) > (end & mask), the last but one cacheline won't be invalidated as it should. Fix this by rounding `end' down to the nearest cacheline boundary if it gets adjusted due to misalignment. Also flush the write buffer unconditionally -- if the dcache wrote back a line just before we invalidated it, the dirty data may be sitting in the write buffer waiting to corrupt our buffer later.

It is only used for PAE kernels in set_64bit. The problem is that due to a old Windows bug many CPUs need magic MSRs to enable CMPXCHG64, and we can't do that nicely early enough before it is potentially used. But since we only need it in PAE kernels so only force the checking for CMPXCHG65 with PAE.

posix-timers which deliver an ignored signal are currently rearmed in the timer softirq: This is necessary because the timer needs to be delivered again when SIG_IGN is removed. This is not a problem, when the interval is reasonable. With high resolution timers enabled one might arm a posix timer with a very small interval and ignore the signal. This might lead to a softirq starvation when the interval is so small that the timer is requeued onto the softirq pending list right away. This problem was pointed out by Jan Kiszka. Thanks Jan ! The correct solution would be to stop the timer, when the signal is ignored and rearm it when SIG_IGN is removed. Unfortunately this requires modification in sigaction and involves non trivial sighand locking. It's too late in the release cycle for such a change. For now we just keep the timer running and enforce that the timer only fires every jiffie. This does not break anything as we keep the overrun counter correct. It adds a little inaccuracy to the timer_gettime() interface, but... The more complex change is necessary anyway to fix another short coming of the current implementation, which I discovered while looking at this problem: A pending signal is discarded when SIG_IGN is set. In case that a posixtimer signal is pending then it is discarded as well, but when SIG_IGN is removed later nothing rearms the timer. This is not new, it's that way since posix timers have been merged. So nothing to worry about right now. I have a working solution to fix all of this, but the impact is too large for both stable and 2.6.22. I'm going to send it out for review in the next days. This should go into 2.6.21.stable as well.

IPoIB connected mode currently rejects a connection request unless the supported MTU is >= the local netdevice MTU. This breaks interoperability with implementations that might have tweaked IPOIB_CM_MTU, and there's real no longer a reason to do so: this test is just a leftover from when we did not tweak MTU per-connection.

Fix a crasher bug in IPoIB CM: once a QP is in the RTR state, a receive completion (or even an asynchronous error) might be observed on this QP, so we have to initialize all of our receive data structures before moving to the RTR state. As an optimization (since modify_qp might take a long time), the jiffies update done when moving RX to the passive_ids list is also left in place to reduce the chance of the RX being misdetected as stale.

If ib_umem_release() is called after ib_uverbs_close() sets context->closing, then a process can get stuck in a D state, because the code boils down to if (down_write_trylock(&mm->mmap_sem)) down_write(&mm->mmap_sem); which is obviously a stupid instant deadlock. Fix the code so that we only try to take the lock once. This bug was introduced in commit f7c6a7b5 ("IB/uverbs: Export ib_umem_get()/ib_umem_release() to modules") which fortunately never made it into a release, and was reported by Pete Wyckoff <pw@osc.edu>.
