2016-09-22regmap: fix deadlock on _regmap_raw_write() error pathNikita Yushchenko1-1/+5
Commit 815806e39bf6 ("regmap: drop cache if the bus transfer error") added a call to regcache_drop_region() to error path in _regmap_raw_write(). However that path runs with regmap lock taken, and regcache_drop_region() tries to re-take it, causing a deadlock. Fix that by calling map->cache_ops->drop() directly.

2016-09-22tcp: properly account Fast Open SYN-ACK retransYuchung Cheng3-1/+4
Since the TFO socket is accepted right off SYN-data, the socket owner can call getsockopt(TCP_INFO) to collect ongoing SYN-ACK retransmission or timeout stats (i.e., tcpi_total_retrans, tcpi_retransmits).

The highest 3bits of the 4 layers buffers are all part of the same register.

2016-09-21i2c-eg20t: fix race between i2c init and interrupt enableYadi.hu1-7/+11
the eg20t driver call request_irq() function before the pch_base_address, base address of i2c controller's register, is assigned an effective value. there is one possible scenario that an interrupt which isn't inside eg20t arrives immediately after request_irq() is executed when i2c controller shares an interrupt number with others. since the interrupt handler pch_i2c_handler() has already active as shared action, it will be called and read its own register to determine if this interrupt is from itself. At that moment, since base address of i2c registers is not remapped in kernel space yet,so the INT handler will access an illegal address and then a error occurs.

2016-09-21MIPS: vDSO: Fix Malta EVA mapping to vDSO page structsJames Hogan1-4/+4
The page structures associated with the vDSO pages in the kernel image are calculated using virt_to_page(), which uses __pa() under the hood to find the pfn associated with the virtual address. The vDSO data pointers however point to kernel symbols, so __pa_symbol() should really be used instead. Since there is no equivalent to virt_to_page() which uses __pa_symbol(), fix init_vdso_image() to work directly with pfns, calculated with __phys_to_pfn(__pa_symbol(...)). This issue broke the Malta Enhanced Virtual Addressing (EVA) configuration which has a non-default implementation of __pa_symbol(). This is because it uses a physical alias so that the kernel executes from KSeg0 (VA 0x80000000 -> PA 0x00000000), while RAM is provided to the kernel in the KUSeg range (VA 0x00000000 -> PA 0x80000000) which uses the same underlying RAM. Since there are no page structures associated with the low physical address region, some arbitrary kernel memory would be interpreted as a page structure for the vDSO pages and badness ensues.

2016-09-21drm/rockchip: Always signal event in next vblank after cfg_doneTomasz Figa1-44/+10
This patch makes the driver send the pending vblank event in next vblank following the commit, relying on vblank signalling improvements done in previous patches. This gives us vblank events that always represent the real moment of changes hitting on the screen (which was the case only for complete FB changes before) and lets us remove the manual window update check.

2016-09-21drm/rockchip: Do not enable vblank without eventTomasz Figa1-11/+4
Originally we needed to enable vblank for any atomic commit to kick the PSR machine, but that was changed and we no longer need to do so from a vblank interrupt. Let's return to original behavior of enabling vblank only if it is really necessary. This essentially reverts commit 5b6804034ae9 ("drm/rockchip: Enable vblank without event").

2016-09-21drm/rockchip: Replace custom wait_for_vblanks with helperTomasz Figa3-78/+1
Currently the driver uses a custom function to wait for flip to complete after an atomic commit. It was needed before because of two problems: - there is no hardware vblank counter, so the original helper would have a race condition with the vblank interrupt, - the driver didn't support unreferencing cursor framebuffers asynchronously to the commit, which was what the helper expected. Since both problems have been solved by previous patches, we can now make the driver use the generic helper and remove custom waiting code. Signed-off-by: Tomasz Figa <[email protected]>
2016-09-21drm/rockchip: Unreference framebuffers from flip workTomasz Figa1-0/+41
Currently the driver waits for vblank and then unreferences old framebuffers from atomic commit code path. This is however breaking the legacy cursor API, which requires the updates to be fully asynchronous. Instead of just adding a special case for cursor, we can have actually smaller amount of code to unreference any changed framebuffer from a flip work. Signed-off-by: Tomasz Figa <[email protected]>
2016-09-21drm/rockchip: Avoid race with vblank count incrementTomasz Figa1-0/+34
Since VOP does not have a hardware vblank count register, the ongoing commit might be racing with a requested vblank interrupt, which would increment the software vblank counter before the changes being committed actually happen. To avoid this, we can extend .atomic_flush(), so after it sets cfg_done bit, it polls the vblank interrupt bit until it's inactive to make sure that any old vblank interrupt gets to the handler and then uses synchronize_irq(vop->irq) to make sure the handler finishes running. The polling case should happen very rarely, but even if, the total wait time should be relatively low and in practice almost equal to the vop hardirq handler running time.

2016-09-21drm/rockchip: Get rid of some unnecessary codeTomasz Figa1-18/+0

2016-09-21drm/rockchip: Clear interrupt status bits before enablingTomasz Figa1-0/+3
The enable register only masks the raw status bits to signal CPU interrupt only for enabled interrupts. The status bits are activated regardless of the enable register. This means that we might have an old interrupt event queued, which we are not interested in. To avoid getting a spurious interrupt signalled, we have to clear the old bit before we update the enable register. Signed-off-by: Tomasz Figa <[email protected]>
