* OMAP1: AMS_DELTA: add modem supportJanusz Krzysztofik2009-08-281-0/+38
| | | | | | | | | | | | | | This patch adds support for modem device found on Amstrad E3 (Delta) board. Based on earlier patch by Jonathan McDowell, available at http://the.earth.li/pub/e3/2.6.19/ams-delta-modem.patch. Modified after Ladislav Michl's arch/arm/mach-omap1/board-voiceblue.c. This patch is dependent on 8250 driver changes getting accepted upstream: http://git.kernel.org/?p=linux/kernel/git/sfr/linux-next.git;a=commit;h=7053133124d5cdf207c1168c7a0c582a18e12ea7 Signed-off-by: Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> Signed-off-by: Tony Lindgren <tony@atomide.com>
* OMAP: GPIO: Avoid generating extra IRQsEero Nurkkala2009-08-281-4/+23
| | | | | | | | | | | It is possible for GPIO IRQ lines configured with falling edge triggering only to get IRQs at the rising edge upon the exit of offmode. And vice versa.

* OMAP: UART: drop OMAP_TAG_UART, enable all UARTs, auto-disabled on idleKalle Valo2009-08-2829-149/+0
| | | | | | | | | | | | | | | | OMAP tags are deprecrated so drop them. Drop UART config data which decides which UARTs to enable during boot. This is no longer necessary since serial core code disables clocks after inactivity. Background: with new UART idle code, all on-chip UARTs are idled using a configurable inactivity timer (default 5 seconds.) After the inactivity timer, UART clocks are disabled automatically.

| * sparc64: Validate linear D-TLB misses.David S. Miller2009-08-254-28/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When page alloc debugging is not enabled, we essentially accept any virtual address for linear kernel TLB misses. But with kgdb, kernel address probing, and other facilities we can try to access arbitrary crap. So, make sure the address we miss on will translate to physical memory that actually exists. In order to make this work we have to embed the valid address bitmap into the kernel image. And in order to make that less expensive we make an adjustment, in that the max physical memory address is decreased to "1 << 41", even on the chips that support a 42-bit physical address space. We can do this because bit 41 indicates "I/O space" and thus covers non-memory ranges. The result of this is that: 1) kpte_linear_bitmap shrinks from 2K to 1K in size 2) we need 64K more for the valid address bitmap We can't let the valid address bitmap be dynamically allocated once we start using it to validate TLB misses, otherwise we have crazy issues to deal with wrt. recursive TLB misses and such. If we're in a TLB miss it could be the deepest trap level that's legal inside of the cpu. So if we TLB miss referencing the bitmap, the cpu will be out of trap levels and enter RED state. To guard against out-of-range accesses to the bitmap, we have to check to make sure no bits in the physical address above bit 40 are set. We could export and use last_valid_pfn for this check, but that's just an unnecessary extra memory reference. On the plus side of all this, since we load all of these translations into the special 4MB mapping TSB, and we check the TSB first for TLB misses, there should be absolutely no real cost for these new checks in the TLB miss path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, srmmu uses different trap table register values to allow determination of the cpu we're on. All of the trap tables have identical content, they just sit at different offsets from the first trap table, and the offset shifted down and masked out determines the cpu we are on. The code tries to free them up when they aren't actually used (don't have all 4 cpus, we're on sun4d, etc.) but that causes problems. For one thing it triggers false positives in the DMA debugging code. And fixing that up while preserving this relative offset thing isn't trivial. So just kill the freeing code, it costs us at most 3 pages, big deal... Signed-off-by: David S. Miller <davem@davemloft.net>

This results in a deadlock in this scenario. cpu A holds clockevents_lock in clockevents_notify() with irqs enabled cpu B waits for clockevents_lock in clockevents_notify() with irqs disabled cpu C doing set_mtrr() which will try to rendezvous of all the cpus. This will result in C and A come to the rendezvous point and waiting for B. B is stuck forever waiting for the spinlock and thus not reaching the rendezvous point. Fix the clockevents code so that clockevents_lock is taken with interrupts disabled and thus avoid the above deadlock. Also call lapic_timer_propagate_broadcast() on the destination cpu so that we avoid calling smp_call_function() in the clockevents notifier chain. This issue left us wondering if we need to change the MTRR rendezvous logic to use stop machine logic (instead of smp_call_function) or add a check in spinlock debug code to see if there are other spinlocks which gets taken under both interrupts enabled/disabled conditions.

In order to get satisfactory response then, we need to employ every noise-reduction trick in the driver's arsenal. After extensive fiddling I've found some good settings: 1) We keep vref on all the time to dramatically reduce settling times (at the cost of a tiny increase in power consumption). 2) Despite 1 the settling time is still non-zero. 500uS is plenty of time for the signals to settle 3) Despite 1 and 2 there's still a little bit of noise around. By setting a pen recheck delay we make the panel feel less touchy and twitchy. Someone with more time and patience myself might be able to tune this numbers further but these settings are now perfectly acceptable for normal use. Tested on ezLCD+101 though should only improve response on other ezLCD+/ favr-32 boards too.

* | | | | | x86: don't call '->send_IPI_mask()' with an empty maskLinus Torvalds2009-08-211-11/+10

That commit added a WARN_ON() for that case, and avoided the resulting problem, but didn't fix the underlying reason for why those empty mask cases happened. This fixes that, by checking the result of 'cpumask_andnot()' of the current CPU actually has any other CPU's left in the set of CPU's to be sent a TLB flush, and not calling down to the IPI code if the mask is empty. The reason this started happening at all is that we started passing just the CPU mask pointers around in commit 4595f9620 ("x86: change flush_tlb_others to take a const struct cpumask"), and when we did that, the cpumask was no longer thread-local. Before that commit, flush_tlb_mm() used to create it's own copy of 'mm->cpu_vm_mask' and pass that copy down to the low-level flush routines after having tested that it was not empty. But after changing it to just pass down the CPU mask pointer, the lower level TLB flush routines would now get a pointer to that 'mm->cpu_vm_mask', and that could still change - and become empty - after the test due to other CPU's having flushed their own TLB's. See http://bugzilla.kernel.org/show_bug.cgi?id=13933 for details.

* | | | | | x86: don't send an IPI to the empty set of CPU'sLinus Torvalds2009-08-211-0/+3

So just warn if a caller gives us an empty mask, and ignore it. This fixes a regression in 2.6.30.x, due to commit 4595f9620 ("x86: change flush_tlb_others to take a const struct cpumask"), documented here: http://bugzilla.kernel.org/show_bug.cgi?id=13933 which causes a silent lock-up. It only seems to happen on PPro, P2, P3 and Athlon XP cores. Most developers sadly (or not so sadly, if you're a developer..) have more modern CPU's. Also, on x86-64 we don't use the flat APIC mode, so it would never trigger there even if the APIC didn't like sending an empty IPI mask.
