2017-08-14ARM: dts: dra7xx: Enable NAND dma prefetch by defaultFranklin S Cooper Jr2-0/+2
Currently the default method of prefetch polled shows the highest possible read and write speed when minimal non NAND background activity is being done. But it is also very CPU intensive to reach these high speeds (CPU load of 99% via mtd performance tests). While DMA prefetch only uses 50% of the CPU to achieve around 23% less in top read and write performance. However, as the non NAND CPU load increases the read and write performance takes a large hit when using polled prefetch. Therefore, prefetch dma mode ends up outperforming prefetch polled in general "system level" test. So switch to using dma prefetch by default since it is likely what most users would prefer.

2017-08-14ARM: dts: Disable HDMI CEC internal pull-upsTony Lindgren8-8/+8
Devices using an external encoder, ESD protection and level shifter such as tpd12s015 or ip4791cz12 have the CEC pull in the encoder chip. And on var-som-om44, there is external pull up resistor R30. So the internal CEC pull-up resistor needs to be disabled as otherwise the external and internal pull are parallel making the pull value much smaller than intended. This leads into the CEC not working as reported by Hans Verkuil <hverkuil@xs4all.nl>.

2017-08-11mm: fix MADV_[FREE|DONTNEED] TLB flush miss problemMinchan Kim1-1/+6
Nadav reported parallel MADV_DONTNEED on same range has a stale TLB problem and Mel fixed it[1] and found same problem on MADV_FREE[2]. Quote from Mel Gorman: "The race in question is CPU 0 running madv_free and updating some PTEs while CPU 1 is also running madv_free and looking at the same PTEs. CPU 1 may have writable TLB entries for a page but fail the pte_dirty check (because CPU 0 has updated it already) and potentially fail to flush. Hence, when madv_free on CPU 1 returns, there are still potentially writable TLB entries and the underlying PTE is still present so that a subsequent write does not necessarily propagate the dirty bit to the underlying PTE any more. Reclaim at some unknown time at the future may then see that the PTE is still clean and discard the page even though a write has happened in the meantime. I think this is possible but I could have missed some protection in madv_free that prevents it happening." This patch aims for solving both problems all at once and is ready for other problem with KSM, MADV_FREE and soft-dirty story[3]. TLB batch API(tlb_[gather|finish]_mmu] uses [inc|dec]_tlb_flush_pending and mmu_tlb_flush_pending so that when tlb_finish_mmu is called, we can catch there are parallel threads going on. In that case, forcefully, flush TLB to prevent for user to access memory via stale TLB entry although it fail to gather page table entry. I confirmed this patch works with [4] test program Nadav gave so this patch supersedes "mm: Always flush VMA ranges affected by zap_page_range v2" in current mmotm. NOTE: This patch modifies arch-specific TLB gathering interface(x86, ia64, s390, sh, um). It seems most of architecture are straightforward but s390 need to be careful because tlb_flush_mmu works only if mm->context.flush_mm is set to non-zero which happens only a pte entry really is cleared by ptep_get_and_clear and friends. However, this problem never changes the pte entries but need to flush to prevent memory access from stale tlb.

This patch is a preparatory patch for solving race problems caused by TLB batch. For that, we will increase/decrease TLB flush pending count of mm_struct whenever tlb_[gather|finish]_mmu is called.

2017-08-10ARM: dts: dra72-evm-revc: workaround incorrect DP83867 RX_CTRL pin strapSekhar Nori1-0/+2
The DRA72 EVM Rev C straps the DP83867 GigaBit Ethernet phy's RX_DV/RX_CTRL pin in mode 1. Unfortunately, the phy data manual disallows this. Add "ti,dp83867-rxctrl-strap-quirk" property to the phy's device-tree node to allow kernel to enable software workaround for this incorrect strap setting. This is as suggested by the phy's datamanual and ensures proper operation of this PHY. This needs to be done for both instances of this PHY present on the board.
