2020-03-04s390/mm: fix panic in gup_fast on large pudGerald Schaefer1-0/+6
On s390 there currently is no implementation of pud_write(). That was ok as long as we had our own implementation of get_user_pages_fast() which checked for pud protection by testing the bit directly w/o using pud_write(). The other callers of pud_write() are not reachable on s390. After commit 1a42010cdc26 ("s390/mm: convert to the generic get_user_pages_fast code") we use the generic get_user_pages_fast(), which does call pud_write() in pud_access_permitted() for FOLL_WRITE access on a large pud. Without an s390 specific pud_write(), the generic version is called, which contains a BUG() statement to remind us that we don't have a proper implementation. This results in a kernel panic. Fix this by providing an implementation of pud_write().

2020-03-04usb: dwc3: gadget: Update chain bit correctly when using sg listPratham Pratap1-1/+8
If scatter-gather operation is allowed, a large USB request is split into multiple TRBs. For preparing TRBs for sg list, driver iterates over the list and creates TRB for each sg and mark the chain bit to false for the last sg. The current IOMMU driver is clubbing the list of sgs which shares a page boundary into one and giving it to USB driver. With this the number of sgs mapped it not equal to the the number of sgs passed. Because of this USB driver is not marking the chain bit to false since it couldn't iterate to the last sg. This patch addresses this issue by marking the chain bit to false if it is the last mapped sg. At a practical level, this patch resolves USB transfer stalls seen with adb on dwc3 based db845c, pixel3 and other qcom hardware after functionfs gadget added scatter-gather support around v4.20. Credit also to Anurag Kumar Vulisha <[email protected]> who implemented a very similar fix to this issue.

Commit 4d7201cda226 ("usb: usb251xb: add vdd supply support") didn't covered the non-DT use-case and so the regualtor_enable() call during probe will fail on those platforms. Also the commit didn't handled the error case correctly. Move devm_regulator_get() out of usb251xb_get_ofdata() to address the 1st issue. This can be done without worries because devm_regulator_get() handles the non-DT use-case too. Add devm_add_action_or_reset() to address the 2nd bug.

2020-03-04usb: cdns3: gadget: toggle cycle bit before reset endpointPeter Chen1-3/+14
If there are TRBs pending during reset endpoint operation, the DMA will advance after reset operation, but it isn't expected, since the data is not yet available (For OUT, the data is not yet available). After the data is ready, there won't be any interrupt since the EP_TRADDR already points to next TRB entry and doorbell is not set. To fix it, it toggles cycle bit before reset operation, and restores it after reset, it could avoid unexpected DMA advance due to cycle bit is for software during the endpoint reset operation.

This occurred because the author was also working on a potential extension to devlink regions which included this trigger command, and accidentally squashed the documentation incorrectly.

Place phylink_start()/phylink_stop() inside dsa_port_enable() and dsa_port_disable(), which ensures that we call phylink_stop() before tearing down phylink - which is a documented requirement. Failure to do so can cause use-after-free bugs.
