* [PATCH] sysrq: showBlockedTasks is sysrq-WRandy Dunlap2007-02-01
| | | | | | | | | | | | | | | | | | Change SysRq showBlockedTasks from sysrq-X to sysrq-W and show that in the Help message. It was previously done via X, but X is already used for Xmon on ppc & powerpc platforms and this collision needs to be avoided. All callers of register_sysrq_key() are now marked in the sysrq op/key table. I didn't mark 'h' as Help because Help is just printed for any unknown key, such as '?'. Added some omitted sysrq key entries in the sysrq.txt file.

Only after the call to unmap_mapping_range() are we sure that the page can no longer be dirtied. In order to fix this, NFS has hooked the releasepage() method and tries to write the page out between the call to unmap_mapping_range() and the call to remove_mapping(). This, however leads to deadlocks in the page reclaim code, where the page may be locked without holding a reference to the inode or dentry. Fix is to add a new address_space_operation, launder_page(), which will attempt to write out a dirty page without releasing the page lock.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since get_user_pages() may be used with processes other than the current process and calls flush_anon_page(), flush_anon_page() has to cope in some way with non-current processes. It may not be appropriate, or even desirable to flush a region of virtual memory cache in the current process when that is different to the process that we want the flush to occur for. Therefore, pass the vma into flush_anon_page() so that the architecture can work out whether the 'vmaddr' is for the current process or not. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* | Revert "[PATCH] x86-64: Try multiple timer variants in check_timer"Linus Torvalds2007-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit b026872601976f666bae77b609dc490d1834bf77, which has been linked to several problem reports with IO-APIC and the timer. Machines either don't boot because the timer doesn't happen, or we get double timer interrupts because we end up double-routing the timer irq through multiple interfaces. See for example http://lkml.org/lkml/2006/12/16/101 http://lkml.org/lkml/2007/1/3/9 http://bugzilla.kernel.org/show_bug.cgi?id=7789 about some of the discussion. Patches to fix this cleanup exist (and have been confirmed to work fine at least for some of the affected cases) and we'll revisit it for 2.6.21, but this late in the -rc series we're better off just reverting the incomplete commit that caused the problems.

Sysfs based tools and libraries can start converting right away. - Issue a warning for legacy adapter drivers that don't provide any physical device node; so systems with those drivers will know to fix this problem earlier.

When the watchdog timer expires, the equivalent action of a "fan enable" command is executed. The watchdog timer is reset at every reception of a fan control command that could change the state of the fan itself. This command is meant to be used by userspace fan control daemons, to make sure the fan is never left set to an unsafe level because of userspace problems. Users of the X31/X40/X41 "speed" command are on their own, the current implementation of "speed" is just too incomplete to be used safely, anyway. Better to never use it, and just use the "level" command instead. The watchdog is programmed using echo "watchdog <number>" > fan, where number is the number of seconds to wait before doing an "enable", and zero disables the watchdog.

It uses a DMI match to detect ThinkPads with a new-style embedded controller, that are known to have forward- compatible register maps and use 0x00 to fill in non-used registers and export thermal sensors at EC offsets 0x78-7F and 0xC0-C7. Direct ACPI EC register access is implemented for 8-sensor and 16-sensor new-style ThinkPad controller firmwares as an experimental feature. The code does some limited sanity checks on the temperatures read through EC access, and will default to the old ACPI TMP0-7 mode if anything is amiss. Userspace ABI is not changed for 8 sensors, but /proc/acpi/ibm/thermal is extended for 16 sensors if the firmware supports 16 sensors. A documentation update is also provided. The information about the ThinkPad register map was determined by studying ibm-acpi "ecdump" output from various ThinkPad models, submitted by subscribers of the linux-thinkpad mailinglist. Futher information was gathered from the DSDT tables, as they describe the EC register map in recent ThinkPads. DSDT source shows that TMP0-7 access and direct register access are actually the same thing on these firmwares, but unfortunately IBM never did update their DSDT EC register map to export TMP8-TMP15 for the second range of sensors.

This looks like a hardware error, at the level of noise to those ports' overcurrent input signals (or non-debounced VBUS comparators). This surfaces to users as truly massive amounts of syslog spam from khubd (which is appropriate for real hardware problems, except for the volume from multiple ports). Using this new "ignore_oc" flag helps such systems work more sanely, by preventing such indications from getting to khubd (and spamming syslog). The downside is of course that true overcurrent errors will be masked; they'll appear as spontaneous disconnects, without the diagnostics that will let users troubleshoot issues like short-circuited cables. In addition, controllers with no devices attached will be forced to poll for new devices rather than relying on interrupts, since each overcurrent event would generate a new interrupt. This patch (as826) is essentially a copy of David Brownell's ignore_oc patch for ehci-hcd, ported to uhci-hcd.
