* ARM i.MX51 clock: Fix regression since enabling MIPI/HSP clocksSascha Hauer2012-12-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | The MIPI/HSP clocks were recently turned on in the i.MX51 clock tree. It turned out that the system does not work properly when the MIPI/HSP clocks are enabled, but the IPU clock is disabled. This happens when IPU support is disabled. In this case the IPU clock gets disabled when the clock framework turns off unused clock in a late_initcall. This is broken since: | commit 9a2d4825a9368e018003a2732a61be063d178f67 | Author: Sascha Hauer <s.hauer@pengutronix.de> | Date: Tue Jun 5 13:53:32 2012 +0200 | | ARM i.MX5: switch IPU clk support to devicetree bindings | | The i.MX5 clk support has platform based clock bindings for the | IPU. IPU support is devicetree only, so move them over to devicetree | based bindings. Also, enable MIPI clocks which do not have a device | associated with, but still need to be enabled to do graphics on | i.MX51. This patch fixes this by setting some reserved bits in the CCM as recommended in the reference manual. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Tested-by: Shawn Guo <shawn.guo@linaro.org>

| * m68knommu: modify clock code so it can be used by all ColdFire CPU typesGreg Ungerer2012-12-04
| | | | | | | | | | | | | | | | | | | | | | | | The existing clk.c code for ColdFire CPUs has one set of functions to support those CPU types that have selectable clocks (those with a PPMCR register), and a duplicate simpler set for those with static clocks. Modify the clk.c code so there is just one set of support functions. All CPU types now define a list of clocks (in "struct clk"s), so we only need a single set of clock functions.

In almost all respects balancenuma is the dumbest of the three because its main impact is on the VM side with no attempt to be smart about scheduling. In the interest of getting the ball rolling, it would be desirable to see this much merged for 3.8 with the view to building scheduler smarts on top and adapting the VM where required for 3.9. The most recent set of comparisons available from different people are mel: https://lkml.org/lkml/2012/12/9/108 mingo: https://lkml.org/lkml/2012/12/7/331 tglx: https://lkml.org/lkml/2012/12/10/437 srikar: https://lkml.org/lkml/2012/12/10/397 The results are a mixed bag. In my own tests, balancenuma does reasonably well. It's dumb as rocks and does not regress against mainline. On the other hand, Ingo's tests shows that balancenuma is incapable of converging for this workloads driven by perf which is bad but is potentially explained by the lack of scheduler smarts. Thomas' results show balancenuma improves on mainline but falls far short of numacore or autonuma. Srikar's results indicate we all suffer on a large machine with imbalanced node sizes. My own testing showed that recent numacore results have improved dramatically, particularly in the last week but not universally. We've butted heads heavily on system CPU usage and high levels of migration even when it shows that overall performance is better. There are also cases where it regresses. Of interest is that for specjbb in some configurations it will regress for lower numbers of warehouses and show gains for higher numbers which is not reported by the tool by default and sometimes missed in treports. Recently I reported for numacore that the JVM was crashing with NullPointerExceptions but currently it's unclear what the source of this problem is. Initially I thought it was in how numacore batch handles PTEs but I'm no longer think this is the case. It's possible numacore is just able to trigger it due to higher rates of migration. These reports were quite late in the cycle so I/we would like to start with this tree as it contains much of the code we can agree on and has not changed significantly over the last 2-3 weeks." * tag 'balancenuma-v11' of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma: (50 commits) mm/rmap, migration: Make rmap_walk_anon() and try_to_unmap_anon() more scalable mm/rmap: Convert the struct anon_vma::mutex to an rwsem mm: migrate: Account a transhuge page properly when rate limiting mm: numa: Account for failed allocations and isolations as migration failures mm: numa: Add THP migration for the NUMA working set scanning fault case build fix mm: numa: Add THP migration for the NUMA working set scanning fault case. mm: sched: numa: Delay PTE scanning until a task is scheduled on a new node mm: sched: numa: Control enabling and disabling of NUMA balancing if !SCHED_DEBUG mm: sched: numa: Control enabling and disabling of NUMA balancing mm: sched: Adapt the scanning rate if a NUMA hinting fault does not migrate mm: numa: Use a two-stage filter to restrict pages being migrated for unlikely task<->node relationships mm: numa: migrate: Set last_nid on newly allocated page mm: numa: split_huge_page: Transfer last_nid on tail page mm: numa: Introduce last_nid to the page frame sched: numa: Slowly increase the scanning period as NUMA faults are handled mm: numa: Rate limit setting of pte_numa if node is saturated mm: numa: Rate limit the amount of memory that is migrated between nodes mm: numa: Structures for Migrate On Fault per NUMA migration rate limiting mm: numa: Migrate pages handled during a pmd_numa hinting fault mm: numa: Migrate on reference policy ...

The NUMA hinting page fault will clear the NUMA bit and set the present bit again to resolve the page fault. The expectation is that a NUMA hinting page fault is used as part of a placement policy that decides if a page should remain on the current node or migrated to a different node.

Arming the NUMA hinting page fault mechanism works similarly to setting up a mprotect(PROT_NONE) virtual range: the present bit is cleared at the same time that _PAGE_NUMA is set, so when the fault triggers we can identify it as a NUMA hinting page fault. _PAGE_NUMA on x86 shares the same bit number of _PAGE_PROTNONE (but it could also use a different bitflag, it's up to the architecture to decide). It would be confusing to call the "NUMA hinting page faults" as "do_prot_none faults". They're different events and _PAGE_NUMA doesn't alter the semantics of mprotect(PROT_NONE) in any way. Sharing the same bitflag with _PAGE_PROTNONE in fact complicates things: it requires us to ensure the code paths executed by _PAGE_PROTNONE remains mutually exclusive to the code paths executed by _PAGE_NUMA at all times, to avoid _PAGE_NUMA and _PAGE_PROTNONE to step into each other toes. Because we want to be able to set this bitflag in any established pte or pmd (while clearing the present bit at the same time) without losing information, this bitflag must never be set when the pte and pmd are present, so the bitflag picked for _PAGE_NUMA usage, must not be used by the swap entry format.

The write bit is only ever set together with the dirty bit. Because we only ever upgrade a PTE, it is safe to skip flushing entries on remote TLBs. The worst that can happen is a spurious page fault on other CPUs, which would flush that TLB entry. Lazily letting another CPU incur a spurious page fault occasionally is (much!) cheaper than aggressively flushing everybody else's TLB.

This is clearer, as hdmi and tpd12s015 are separate devices, and it also allows us to mux those separately with DT.
