5d7e0d2 Andrew Morton05 July 2008, 08:02:01 UTCFix pagemap_read() use of struct mm_walk Fix some issues in pagemap_read noted by Alexey: - initialize pagemap_walk.mm to "mm" , so the code starts working as advertised - initialize ->private to "&pm" so it wouldn't immediately oops in pagemap_pte_hole() - unstatic struct pagemap_walk, so two threads won't fsckup each other (including those started by root, including flipping ->mm when you don't have permissions) - pagemap_read() contains two calls to ptrace_may_attach(), second one looks unneeded. - avoid possible kmalloc(0) and integer wraparound.

4915399 Mike Miller04 July 2008, 17:00:02 UTCcciss: read config to obtain max outstanding commands per controller This patch changes the way we determine the maximum number of outstanding commands for each controller. Most Smart Array controllers can support up to 1024 commands, the notable exceptions are the E200 and E200i. The next generation of controllers which were just added support a mode of operation called Zero Memory Raid (ZMR). In this mode they only support 64 outstanding commands. In Full Function Raid (FFR) mode they support 1024. We have been setting the queue depth by arbitrarily assigning some value for each controller. We needed a better way to set the queue depth to avoid lots of annoying "fifo full" messages. So we made the driver a little smarter. We now read the config table and subtract 4 from the returned value. The -4 is to allow some room for ioctl calls which are not tracked the same way as io commands are tracked. Please consider this for inclusion.

51597ac Bastian Blank04 July 2008, 17:00:00 UTCAlpha Linux kernel fails with inconsistent kallsyms data The build of the Alpha Linux kernel currently fails[1] with inconsistent kallsyms data. As I never saw that before, I thought about hardware problems. But in fact it is a bug in the Linux kernel. The end of the rodata section is marked with the "__end_rodata" symbol. This symbol have different aligning constraints than the inittext parts and therefor the start marked "_sinittext". Because of that the __end_rodata symbol shifts between < _sinittext and == _sinittext. The later variant is seen as a code symbol and recorded in the kallsyms data. On fix would be to move the exception table a little bit and get some space between that two areas.

I tested the rmmod & write path but didn't check the read path. I am sorry. The read logic changed and spidev_sync_read() + spidev_sync_write() do not return zero on success anymore but the number of bytes that has been transfered over the bus. This patch changes the logic and copy_to_user() gets called again. The write path returns the number of bytes which are written to the underlying device what may be less than the requested size. This patch makes the same change to the read path or else we request a read of 20 bytes, get 10, don't call copy to user and report to the user that we read 10 bytes.

It's still a little unclear how long the LF money will last for the fellowship, but for the foreseeable future, I'll be working on: * Properly documenting every new Linux kernel-userland (and glibc) API, and every API change, that is released into the mainline kernel, ideally before actual release. (That's the ideal, but there's a quite a backlog, so I'm not going to achieve the ideal immediately.) * Testing new APIs, again ideally before they are released into the mainline kernel, and probably doing some light bug fixing while I'm at it (e.g., the recent utimensat() work). * Design review of new APIs, which of course can only usefully be done before they are released into the mainline kernel. * And of course accepting patches and dealing with bug reports for existing man pages.

Commit 95b570c9cef3b12356454c7112571b7e406b4b51 ("Taint kernel after WARN_ON(condition)") introduced a TAINT_WARN that was implemented for all architectures using the generic warn_on_slowpath(), which excluded any architecture that set HAVE_ARCH_WARN_ON. As all of the architectures that implement their own WARN_ON() all go through the report_bug() path (specifically handling BUG_TRAP_TYPE_WARN), taint the kernel there as well for consistency. Tested on avr32 and sh. Also relevant for s390, parisc, and powerpc.

471d47e Michael Hamel04 July 2008, 16:59:30 UTCrtc-x1205: Fix alarm set I have discovered that the current version of rtc-x1205.c does not work correctly when asked to set the alarm time by the RTC_WKALM_SET ioctl() call. This happens because the alarm registers do not behave like the current-time registers. They are non-volatile. Two things go wrong: - the X1205 requires a 10 msec delay after any attempt to write to the non-volatile registers. The x1205_set_datetime() routine does the write as 8 single-byte writes without any delay. Only the first write succeeds. The second is NAKed because the chip is busy. - the X1205 resets the RWEL bit after any write to the non-volatile registers. This would lock out any further writes after the first even with a 10msec delay. I fix this by doing a single 8-byte write and then waiting 10msec for the chip to be ready. A side effect of this change is that it will speed up x1205_rtc_set_time() which uses the same code. I have also implemented the 'enable' bit in the rtc_wkalm structure, which the existing driver does not attempt to do. I have modified both x1205_rtc_set_alarm() to set the AL0E bit, and x1205_rtc_read_alarm() to return it. I have tested this patch on a LinkSys NSLU2 under OpenWRT, but on no other hardware. On the NSLU2 the X1205 correctly asserts its IRQ pin when the alarm time matches the current time.

Example, if it's now 10am, an alarm firing at 5am will be triggered TOMORROW not today. (Which may also be next month or next year...) This updates that alarm handling in three ways: * Handle alarm rollover in the common cases of RTCs that don't support matching on all date fields. * Skip the invalid-field logic when it's not needed. * Minor bugfix ... tm_isdst should be ignored, it's one of the fields Linux doesn't maintain. A warning is emitted for some of the unhandled rollover cases, but the possible combinations are a bit too numerous to handle every bit of potential hardware and firmware braindamage.

251b97f Peter Zijlstra04 July 2008, 16:59:24 UTCmm: dirty page accounting vs VM_MIXEDMAP Dirty page accounting accurately measures the amound of dirty pages in writable shared mappings by mapping the pages RO (as indicated by vma_wants_writenotify). We then trap on first write and call set_page_dirty() on the page, after which we map the page RW and continue execution. When we launder dirty pages, we call clear_page_dirty_for_io() which clears both the dirty flag, and maps the page RO again before we start writeout so that the story can repeat itself. vma_wants_writenotify() excludes VM_PFNMAP on the basis that we cannot do the regular dirty page stuff on raw PFNs and the memory isn't going anywhere anyway. The recently introduced VM_MIXEDMAP mixes both !pfn_valid() and pfn_valid() pages in a single mapping. We can't do dirty page accounting on !pfn_valid() pages as stated above, and mapping them RO causes them to be COW'ed on write, which breaks VM_SHARED semantics. Excluding VM_MIXEDMAP in vma_wants_writenotify() would mean we don't do the regular dirty page accounting for the pfn_valid() pages, which would bring back all the head-aches from inaccurate dirty page accounting. So instead, we let the !pfn_valid() pages get mapped RO, but fix them up unconditionally in the fault path.

de85422 Stefan Becker01 July 2008, 16:19:22 UTCUSB: fix interrupt disabling for HCDs with shared interrupt handlers USB: fix interrupt disabling for HCDs with shared interrupt handlers As has been discussed several times on LKML, IRQF_SHARED | IRQF_DISABLED doesn't work reliably, i.e. a shared interrupt handler CAN'T be certain to be called with interrupts disabled. Most USB HCD handlers use IRQF_DISABLED and therefore havoc can break out if they share their interrupt with a handler that doesn't use it. On my test machine the yenta_socket interrupt handler (no IRQF_DISABLED) was registered before ehci_hcd and one uhci_hcd instance. Therefore all usb_hcd_irq() invocations for ehci_hcd and for one uhci_hcd instance happened with interrupts enabled. That led to random lockups as USB core HCD functions that acquire the same spinlock could be called twice from interrupt handlers. This patch updates usb_hcd_irq() to always disable/restore interrupts. usb_add_hcd() will silently remove any IRQF_DISABLED requested from HCD code.

29c8f6a David Brownell14 June 2008, 06:59:54 UTCUSB: ohci - record data toggle after unlink This patch fixes a problem with OHCI where canceling bulk or interrupt URBs may lose track of the right data toggle. This seems to be a longstanding bug, possibly dating back to the Linux 2.4 kernel, which stayed hidden because (a) about half the time the data toggle bit was correct; (b) canceling such URBs is unusual; and (c) the few drivers which cancel these URBs either [1] do it only as part of shutting down, or [2] have fault recovery logic, which recovers. For those transfer types, the toggle is normally written back into the ED when each TD is retired. But canceling bypasses the mechanism used to retire TDs ... so on average, half the time the toggle bit will be invalid after cancelation. The fix is simple: the toggle state of any canceled TDs are propagated back to the ED in the finish_unlinks function. (Issue found by leonidv11@gmail.com ...)

See commit 0c96c5979a522c3323c30a078a70120e29b5bdbc Unfortunately this allows the task to migrate after setting up the softirq and raising it. Since softirqs run a queue that is per-cpu we may raise the softirq on the wrong CPU and this will keep the queued softirq task from running. To solve this issue, this patch disables preemption around the releasing of the hrtimer lock and raising of the softirq.

Which is problematic, since non-NUMA only has a single node_zonelists[] entry, and trying to zero the non-existent second one just overwrote the nr_zones field instead. As kswapd uses this value to determine what reclaim work is necessary, the result is that kswapd never reclaims.
