Starting last month, I reached a long-time goal: man-pages finally has a paid, full-time maintainer, thanks to a fellowship from the Linux Foundation. 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.

In linux-next there is a commit ("rcu: split list.h and move rcu-protected lists into rculist.h") that moved the rcu related list iterators from list.h to rculist.h. Add a trivial version of the file now so that various subsystem trees can start using it now for -next changes and so reduce the build errors caused by adding uses of the moved functions.

I'll leave them for now, since proper fix would be not that trivial as few one-liners below. Signed-off-by:

Commit 95b570c9 ("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. Signed-off-by:

When writing /proc/acpi/alarm in adjust mode, e.g. echo "+0000-00-00 00:00:15" >/proc/acpi/alarm The "century" field should be read and added to "year" field before writing, otherwise the CMOS time will go back to 2000 years ago, e.g. # cat /proc/acpi/alarm 0008-06-21 11:38:46 Then the system time may be reset to the date of manufacture after rebooting. This patch fixed this issue. Signed-off-by:

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. [akpm@linux-foundation.org: clean up over-parenthesisation] Signed-off-by:

As reported by Vipul Gandhi, the current serial_match_port() doesn't work for tty-devices using dynamic major number allocation. Fix it. It oopses if you suspend a serial port with _dynamic_ major number. ATM, I think, there's only the drivers/serial/jsm/jsm_driver.c driver, that does it in-tree. Signed-off-by:

While 0e36a9a4 ("rtc: fix readback from /sys/class/rtc/rtc?/wakealarm") made sure that active alarms were never returned with invalid "wildcard" fields (negative), it can still report (wrongly) that the alarm triggers in the past. 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. Signed-off-by:

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. Signed-off-by:

This updates the MAINTAINERS entries for powerpc. It adds Ben H to the overall Linux for PowerPC entry and makes it clear this covers both 32-bit and 64-bit machines. It removes the separate entry we had for Linux on 64-bit PowerPC where Anton and I were listed as maintainers - Anton hasn't been involved in the day-to-day maintenance of the code for several years. Finally, it removes the entry for the Linux for PowerPC boot code where Tom Rini was listed as the maintainer. That code got completely rewritten when we merged 32-bit and 64-bit, and I and the various platform maintainers have been maintaining that code since. Signed-off-by:
