* Merge branch 'safe-dirty-tlb-flush'Linus Torvalds2014-04-285-14/+77
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This merges the patch to fix possible loss of dirty bit on munmap() or madvice(DONTNEED). If there are concurrent writers on other CPU's that have the unmapped/unneeded page in their TLBs, their writes to the page could possibly get lost if a third CPU raced with the TLB flush and did a page_mkclean() before the page was fully written. Admittedly, if you unmap() or madvice(DONTNEED) an area _while_ another thread is still busy writing to it, you deserve all the lost writes you could get. But we kernel people hold ourselves to higher quality standards than "crazy people deserve to lose", because, well, we've seen people do all kinds of crazy things. So let's get it right, just because we can, and we don't have to worry about it. * safe-dirty-tlb-flush: mm: split 'tlb_flush_mmu()' into tlb flushing and memory freeing parts
| * mm: split 'tlb_flush_mmu()' into tlb flushing and memory freeing partsLinus Torvalds2014-04-265-14/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mmu-gather operation 'tlb_flush_mmu()' has done two things: the actual tlb flush operation, and the batched freeing of the pages that the TLB entries pointed at. This splits the operation into separate phases, so that the forced batched flushing done by zap_pte_range() can now do the actual TLB flush while still holding the page table lock, but delay the batched freeing of all the pages to after the lock has been dropped. This in turn allows us to avoid a race condition between set_page_dirty() (as called by zap_pte_range() when it finds a dirty shared memory pte) and page_mkclean(): because we now flush all the dirty page data from the TLB's while holding the pte lock, page_mkclean() will be held up walking the (recently cleaned) page tables until after the TLB entries have been flushed from all CPU's.

Unfortunately, this check is too narrow to catch PJ4 used on Dove itself and breaks iWMMXt support. This patch therefore relaxes the cpuid mask to match both PJ4 and PJ4B. Also, rework the given comment about PJ4/PJ4B modifications to be a little bit more specific about the differences.

Unfortunately, this in turn broke Marvell Armada 370/XP, both comprising Marvell PJ4B CPUs without iWMMXt extension. Instead of only checking for cpuid, which may not be sufficient to determine iWMMXt support, the presence of iWMMXt coprocessors can be checked by enabling and reading the Coprocessor ID register (wCID, register 0 of CP1). Therefore this adds an explicit check for the presence and correct wCID value, before enabling iWMMXt capabilities. As a bonus, also print the iWMMXt version of a detected coprocessor. This has been tested to properly detect iWMMXt presence/absence on: - PJ4, CPUID 0x560f5815, wCID 0x56052001: Marvell Dove, iWMMXt v2 - PJ4B, CPUID 0x561f5811: Marvell Armada 370, no iWMMXt - PJ4B, CPUID 0x562f5841, wCID 0x56052001: Marvell Armada 1500, iWMMXt v2 - PJ4B, CPUID 0x562f5842: Marvell Armada XP, no iWMMXt Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Tested-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Tested-by: Kevin Hilman <khilman@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iwmmxt.S requires special treatment of coprocessor access registers for PJ4 and XScale-based CPUs. It only checks for CPU_PJ4 and drops down to XScale-based treatment on all other architectures.

Setting interrupt affinity to a not online cpu is prohibited and therefor the timer interrupt ends up on the wrong cpu, which leads to nasty complications. The SoC folks tried to hack around that in the SoC code in some more than nasty ways. The proper solution is to have a way to enforce the affinity setting to a not online cpu. The core patch to the genirq code provides that facility and the follow up patches make use of it in the GIC interrupt controller and the exynos timer driver. The change to the core code has no implications to existing users, except for the rename of the locked function and therefor the necessary fixup in mips/cavium. Aside of that, no runtime impact is possible, as none of the existing interrupt chips implements anything which depends on the force argument of the irq_set_affinity() callback" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: clocksource: Exynos_mct: Register clock event after request_irq() clocksource: Exynos_mct: Use irq_force_affinity() in cpu bringup irqchip: Gic: Support forced affinity setting genirq: Allow forcing cpu affinity of interrupts

But there is a special case, where this is actually desired. Some of the ARM SoCs have per cpu timers which require setting the affinity during cpu startup where the cpu is not yet in the online mask. If we can't do that, then the local timer interrupt for the about to become online cpu is routed to some random online cpu. The developers of the affected machines tried to work around that issue, but that results in a massive mess in that timer code. We have a yet unused argument in the set_affinity callbacks of the irq chips, which I added back then for a similar reason. It was never required so it got not used. But I'm happy that I never removed it. That allows us to implement a sane handling of the above scenario. So the affected SoC drivers can add the required force handling to their interrupt chip, switch the timer code to irq_force_affinity() and things just work. This does not affect any existing user of irq_set_affinity(). Tagged for stable to allow a simple fix of the affected SoC clock event drivers.

This does not work currently for GPMC when booted in device tree mode as it attempts to remap the the allocated GPMC partition to the address configured by the device tree plus the device offset. Note that this works just fine when booted with legacy mode. Let's fix the issue by just ignoring any device specific offset while remapping. And let's make sure the remap address confirms to the GPMC 16MB minimum granularity as listed in the TRM for GPMC_CONFIG7 BASEADDRESS bits. Otherwise we can get something like this: omap-gpmc 6e000000.gpmc: cannot remap GPMC CS 1 to 0x01000300 Cc: Pekon Gupta <pekon@ti.com> Reviewed-by: Javier Martinez Canillas <javier@dowhile0.org> Signed-off-by: Tony Lindgren <tony@atomide.com>

Given of_find_property() does return NULL when the node passed is NULL, it did not introduce any functional issues as such, just the fact that the second if check was executed unnecessarily.

Also note that modifying this register trashes any attempted voltage scaling configuration and the change probably should never have gotten merged in the first place.

It also renamed the config from OMAP_USB3 to TI_PIPE3 in Kconfig. However the config name was not changed in omap2plus_defconfig. Fixed it here.
