It was found that the Toshiba laptops with hidden Intel SMBus have SMM code handling the thermal management which accesses the SMBus. Thus it is not safe to unhide it and let Linux access it. We have to leave the SMBus hidden. SMM is a pain, really. This fixes bugs #6315 and #6395, for good this time.

The watchdog implementation excludes low res / non continuous clocksources from being selected as a watchdog reference unintentionally. Allow using jiffies/PIT as a watchdog reference as long as no better clocksource is available. This is necessary to detect TSC breakage on systems, which have no pmtimer/hpet. The main goal of the initial patch (preventing to switch to highres/nohz when no reliable fallback clocksource is available) is still guaranteed by the checks in clocksource_watchdog().

The rework of next_timer_interrupt() fixed the timer wheel bugs, but invented a rounding error versus the next hrtimer event. This is caused by the conversion of the hrtimer internal representation to relative jiffies. This causes bug #8100: http://bugzilla.kernel.org/show_bug.cgi?id=8100 next_timer_interrupt() returns "now" in such a case and causes the code in tick_nohz_stop_sched_tick() to trigger the timer softirq, which is bogus as no timer is due for expiry. This results in an endless context switching between idle and ksoftirqd until a timer is due for expiry. Modify the hrtimer evaluation so that, it returns now + 1, when the conversion results in a delta < 1 jiffie. It's confirmed to resolve bug #8100 Reported-by: NEmil Karlson <jkarlson@cc.hut.fi> Signed-off-by: NThomas Gleixner <tglx@linutronix.de> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

It has been reported by Julian Deng that configuring the pxa27x i2c SCL line as output generates a short negative pulse on it during the call to pxa_gpio_mode(GPIO117_I2CSCL_MD); as it first switches it to output and then configures it for the alternate function. The SCL line is in fact bidirectional and can also be configured as 117 | GPIO_ALT_FN_1_IN, in which case the pulse is not generated. This is exactly what this patch does.

commit f9690982 removed the check for cpu_khz from sched_clock(), which prevented early access to the TSC by non obvious magic. This is harmless as long as the CPU has a TSC. On TSCless systems this results in an illegal instruction trap. Replace tsc_disabled and tsc_unstable by tsc_enabled, which is only set when the tsc is available and not unstable.

Ray Lee reported, that on an UP kernel with "noapic" command line option set, the box locks hard during boot. Adding some debug printks revealed, that the last action on the box before stalling was "Send IPI" - a debug printk which was put into smp_send_timer_broadcast_ipi(). It seems that send_IPI_mask(mask, LOCAL_TIMER_VECTOR) fails when "noapic" is set on the command line on an UP kernel. Aside of that it does not make much sense to trigger an interrupt instead of calling the function directly on the CPU which gets the PIT/HPET interrupt in case of broadcasting.

The segment register slots in struct pt_regs are padded to 32 bits. Some of these are stored with instructions like "pushl %es", which leaves the high 16 bits as they were. So the high bits of these fields in struct pt_regs contain kernel stack garbage. These bits are ignored by everything and never leak to user space, except in core dumps. The user struct pt_regs is always at the base of the thread's kernel stack and so it seems unlikely the information that leaks from here is ever worthwhile so as to be a security concern, but I'm not sure about that. It has been this way for ages; userland consumers of core dumps all mask off these high bits themselves. So it is not urgent. This change masks off the padding bits of the segment register slots in core dumps. ptrace already masks off these high bits, so this makes the values in core dumps consistent with what ptrace would report just before the process died. As I read the processor manuals, the cs and ss values will always be padded with zero bits rather than stack garbage. But unlike "pushl %es", this is not simple to test with a userland program. So I added the two instructions rather than wonder if they are really never necessary. I think that x86_64 does not have this problem (for either 32-bit or 64-bit processes). It only uses "mov" instructions from segment registers, which zero-extend. Signed-off-by: NRoland McGrath <roland@redhat.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
