2007-11-26[ARM] 4604/2: AT91: Master clock divistor on SAM9Andrew Victor
The calculation for the Master clock divisor (MDIV) is different on the SAM9 processors than on the AT91RM9200. Orignal patch from Sascha Erlacher. Also use the defined AT91_PMC_PRES instead of hard-coded bitmasks. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-11-17x86: simplify "make ARCH=x86" and fix kconfig all.configSam Ravnborg
Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in all.config. For a fix the diffstat is nice: 6 files changed, 3 insertions(+), 36 deletions(-) The patch reverts these commits: 0f855aa64b3f63d35a891510cf7db932a435c116 -> kconfig: add helper to set config symbol from environment variable 2a113281f5cd2febbab21a93c8943f8d3eece4d3 -> kconfig: use $K64BIT to set 64BIT with all*config targets Roman Zippel pointed out that kconfig supported string compares so the additional complexity introduced by the above two patches were not needed. With this patch we have following behaviour: # make {allno,allyes,allmod,rand}config [ARCH=...] option \ host arch | 32bit | 64bit ===================================================== ./. | 32bit | 64bit ARCH=x86 | 32bit | 32bit ARCH=i386 | 32bit | 32bit ARCH=x86_64 | 64bit | 64bit The general rule are that ARCH= and native architecture takes precedence over the configuration. So make ARCH=i386 [whatever] will always build a 32-bit kernel no matter what the configuration says. The configuration will be updated to 32-bit if it was configured to 64-bit and the other way around. This behaviour is consistent with previous behaviour so no suprises here. make ARCH=x86 will per default result in a 32-bit kernel but as the only ARCH= value x86 allow the user to select between 32-bit and 64-bit using menuconfig.

2007-11-17x86: on x86_64, correct reading of PC RTC when update in progress in time_64.cDavid P. Reed
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.

2007-11-17x86: fix freeze in x86_64 RTC update code in time_64.cDavid P. Reed
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>

2007-11-17x86: fix cpu-hotplug regressionAndreas Herrmann
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>

dont use the vgetcpu tcache - it's causing problems with tasks migrating, they'll see the old cache up to a jiffy after the migration, further increasing the costs of the migration. In the worst case they see a complete bogus information from the tcache, when a sys_getcpu() call "invalidated" the cache info by incrementing the jiffies _and_ the cpuid info in the cache and the following vdso_getcpu() call happens after vdso_jiffies have been incremented.

2007-11-15[MIPS] irq_cpu: use handle_percpu_irq handler to avoid dropping interrupts.Ralf Baechle
This matters to any sort of device that is wired to one of the CPU interrupt pins on an SMP system. Typically the scenario is most easily triggered with the count/compare timer interrupt where the same interrupt number and thus irq_desc is used on each processor. CPU A CPU B do_IRQ() generic_handle_irq() handle_level_irq() spin_lock(desc_lock) set IRQ_INPROGRESS spin_unlock(desc_lock) do_IRQ() generic_handle_irq() handle_level_irq() spin_lock(desc_lock) IRQ_INPROGRESS set => bail out spin_lock(desc_lock) clear IRQ_INPROGRESS spin_unlock(desc_lock) In case of the cp0 compare interrupt this means the interrupt will be acked and not handled or re-armed on CPU b, so there won't be any timer interrupt until the count register wraps around. With kernels 2.6.20 ... 2.6.23 we usually were lucky that things were just working right on VSMP because the count registers are synchronized on bootup so it takes something that disables interrupts for a long time on one processor to trigger this one. For scenarios where an interrupt is multicasted or broadcasted over several CPUs the existing code was safe and the fix will break it. There is no way to know in the interrupt controller code because it is abstracted from the platform code. I think we do not have such a setup currently, so this should be ok.

2007-11-15[MIPS] Sibyte: Stop timers before programming next even.Ralf Baechle
We have no guarantee by the generic time code that the timer is stopped when the ->next_event method is called. Modifying the Timer Initial Count register while the timer is enabled has UNPREDICTABLE effect according to the BCM1250/BCM1125/BCM1125H User Manual. So stop the timer before reprogramming. This is a paranoia fix; no ill effects have been observed previously. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-11-15[MIPS] Sibyte: Increase minimum oneshot timer interval to two ticks.Ralf Baechle
For the old minimum of a single tick a value of zero would be programmed into the init value register which in the BCM1250/BCM1125/BCM1125H User Manual in the Timer Special Cases section is documented to have UNPREDICTABLE effect. Observable sympthoms of this bug were hangs of several seconds on the console during bootup and later if both dyntick and highres timer options were activated. In theory contiguous mode of the timers is also affected but in an act of hopeless lack of realism I'll assume nobody will ever configure a KERNEL for HZ > 500kHz but if so I leave that to evolution to sort out.

Shadow register support would not possibly have worked on multicore systems. The support code for it was also depending not on MIPS R2 but VSMP or SMTC kernels even though it makes perfect sense with UP kernels. SR sets are a scarce resource and the expected usage pattern is that users actually hardcode the register set numbers in their code. So fix the allocator by ditching it.

2007-11-14CRIS: remove MTD_AMSTD and MTD_OBSOLETE_CHIPS take twoJesper Nilsson
Remove MTD_AMDSTD and MTD_OBSOLETE_CHIPS from defconfig, Kconfig and code, instead we'll use MTD_CFI or MTD_JEDECPROBE.
