My first patch works for him: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=59f4e7d572980a521b7bdba74ab71b21f5995538 But the latest patch does not work for him : http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=8b93789808756bcc1e5c90c99f1b1ef52f839a51 We found that it was necessary to also set the "disable keyboard" flag in the command byte, as the first patch was doing. The second patch tries to minimally modify the command byte, but it is not enough. Please consider this simple one-line patch to help people with low end VIA motherboards reboot when no keyboard is attached. Hiroto Shibuya has verified that this works for him (as I no longer have an afflicted machine). Additional discussion: Note that original patch from Truxton DOES disable keyboard and this has been in main tree since 2.6.14, thus it must have quite a bit of air time already. http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.14.y.git;a=commit;h=59f4e7d572980a521b7bdba74ab71b21f5995538 Note that he only mention "System flag" in the description and comment, but in the code, "disable keyboard" flag is set. outb(0x14, 0x60); /* set "System flag" */ In 2.6.23, he made a change to read the current byte and then mask the flags, but along this change, he only set the "System flag" and dropped the setting of "disable keyboard" flag. http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=commit;h=8b93789808756bcc1e5c90c99f1b1ef52f839a51 outb(cmd | 0x04, 0x60); /* set "System flag" */ So my request is to restore the setting of disable keyboard flag which has been there since 2.6.14 but disappeared in 2.6.23.

| * x86: on x86_64, correct reading of PC RTC when update in progress in time_64.cDavid P. Reed2007-11-171-12/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Correct potentially unstable PC RTC time register reading in time_64.c Stop the use of an incorrect technique for reading the standard PC RTC timer, which is documented to "disconnect" time registers from the bus while updates are in progress. The use of UIP flag while interrupts are disabled to protect a 244 microsecond window is one of the Motorola spec sheet's documented ways to read the RTC time registers reliably. tglx: removed locking changes from original patch, as they gain nothing (read_persistent_clock is only called during boot, suspend, resume - so no hot path affected) and conflict with the paravirt locking scheme (see 32bit code), which we do not want to complicate for no benefit.

| * x86: fix freeze in x86_64 RTC update code in time_64.cDavid P. Reed2007-11-171-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix hard freeze on x86_64 when the ntpd service calls update_persistent_clock() A repeatable but randomly timed freeze has been happening in Fedora 6 and 7 for the last year, whenever I run the ntpd service on my AMD64x2 HP Pavilion dv9000z laptop. This freeze is due to the use of spin_lock(&rtc_lock) under the assumption (per a bad comment) that set_rtc_mmss is called only with interrupts disabled. The call from ntp.c to update_persistent_clock is made with interrupts enabled. Signed-off-by: David P. Reed <dpreed@reed.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
| * ntp: fix typo that makes sync_cmos_clock erraticDavid P. Reed2007-11-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a typo in ntp.c that has caused updating of the persistent (RTC) clock when synced to NTP to behave erratically. When debugging a freeze that arises on my AMD64 machines when I run the ntpd service, I added a number of printk's to monitor the sync_cmos_clock procedure. I discovered that it was not syncing to cmos RTC every 11 minutes as documented, but instead would keep trying every second for hours at a time. The reason turned out to be a typo in sync_cmos_clock, where it attempts to ensure that update_persistent_clock is called very close to 500 msec. after a 1 second boundary (required by the PC RTC's spec). That typo referred to "xtime" in one spot, rather than "now", which is derived from "xtime" but not equal to it. This makes the test erratic, creating a "coin-flip" that decides when update_persistent_clock is called - when it is called, which is rarely, it may be at any time during the one second period, rather than close to 500 msec, so the value written is needlessly incorrect, too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit d435d862baca3e25e5eec236762a43251b1e7ffc ("cpu hotplug: mce: fix cpu hotplug error handling") changed the error handling in mce_cpu_callback. In cases where not all CPUs are brought up during boot (e.g. using maxcpus and additional_cpus parameters) mce_cpu_callback now returns NOTFIY_BAD because for such CPUs cpu_data is not completely filled when the notifier is called. Thus mce_create_device fails right at its beginning: if (!mce_available(&cpu_data[cpu])) return -EIO; As a quick fix I suggest to check boot_cpu_data for MCE. To reproduce this regression: (1) boot with maxcpus=2 addtional_cpus=2 on a 4 CPU x86-64 system (2) # echo 1 >/sys/devices/system/cpu/cpu2/online -bash: echo: write error: Invalid argument dmesg shows: _cpu_up: attempt to bring up CPU 2 failed Signed-off-by: Andreas Herrmann <andreas.herrmann3@amd.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

| * SELinux: return EOPNOTSUPP not ENOTSUPPEric Paris2007-11-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | ENOTSUPP is not a valid error code in the kernel (it is defined in some NFS internal error codes and has been improperly used other places). In the !CONFIG_SECURITY_SELINUX case though it is possible that we could return this from selinux_audit_rule_init(). This patch just returns the userspace valid EOPNOTSUPP.

As a result the cpu may stay at the maximum frequency after a s2ram / resume cycle even though the system is idle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch should apply cleanly to the 2.6.23-git7 kernel.  It changes the powernow-k8 driver code that deals with 3rd generation Opteron, Phenom, and later processors to match the architectural pstate driver described in the AMD64 Architecture Programmer's Manual Volume 2 Chapter 18.  The initial implementation of the hardware pstate driver for PowerNow! used some processor-version specific features, and would not be maintainable in the long term as the processor features changed. This architectural driver should work on all future AMD processors.   Signed-off-by: Mark Langsdorf <mark.langsdorf@amd.com> Signed-off-by: Andreas Herrmann <andreas.herrmann3@amd.com> Signed-off-by: Dave Jones <davej@redhat.com>
* | | dirty page balancing: Get rid of broken unmapped_ratio logicLinus Torvalds2007-11-161-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code harks back to the days when we didn't count dirty mapped pages, which led us to try to balance the number of dirty unmapped pages by how much unmapped memory there was in the system. That makes no sense any more, since now the dirty counts include the mapped pages. Not to mention that the math doesn't work with HIGHMEM machines anyway, and causes the unmapped_ratio to potentially turn negative (which we do catch thanks to clamping it at a minimum value, but I mention that as an indication of how broken the code is). The code also was written at a time when the default dirty ratio was much larger, and the unmapped_ratio logic effectively capped that large dirty ratio a bit. Again, we've since lowered the dirty ratio rather aggressively, further lessening the point of that code.

Thus it is expected to be handled properly on free, which is done in the reqsk_queue_destroy(). However the error path in inet_csk_listen_start() calls the lite version of reqsk_queue_destroy, called __reqsk_queue_destroy, which calls the kfree unconditionally. Fix this and move the __reqsk_queue_destroy into a .c file as it looks too big to be inline. As David also noticed, this is an error recovery path only, so no locking is required and the lopt is known to be not NULL. reqsk_queue_yank_listen_sk is also now only used in net/core/request_sock.c so we should move it there too.
