2020-07-17arm/arm64: defconfig: Update configs to use the new CROS_EC optionsEnric Balletbo i Serra5-5/+15
We refactored the CrOS EC drivers moving part of the code from the MFD subsystem to the platform chrome subsystem. During this change we needed to rename some config options, so, update the defconfigs accordingly.

Newer network cards and switches support offloading of certain packet scheduling, classifying and actions onto the hardware itself. For example, time-aware and credit based schedulers. To use this feature we have to enable the corresponding modules. Please note, that this will also enable NET_SCHED and NET_CLS_ACT as builtin because there is no module option.

Vaibhav explains in the merge commit below why missing v5.8 would be painful and I agreed to try a -rc2 pull because only cosmetics kept this out of -rc1 and his initial versions were posted in more than enough time for v5.8 consideration: 'These patches are tied to specific features that were committed to customers in upcoming distros releases (RHEL and SLES) whose time-lines are tied to 5.8 kernel release.

2020-06-20Revert "pinctrl: freescale: imx: Use 'devm_of_iomap()' to avoid a resource ↵Haibo Chen1-4/+3
leak in case of error in 'imx_pinctrl_probe()'" This reverts commit ba403242615c2c99e27af7984b1650771a2cc2c9. After commit 26d8cde5260b ("pinctrl: freescale: imx: add shared input select reg support"). i.MX7D has two iomux controllers iomuxc and iomuxc-lpsr which share select_input register for daisy chain settings. If use 'devm_of_iomap()', when probe the iomuxc-lpsr, will call devm_request_mem_region() for the region <0x30330000-0x3033ffff> for the first time. Then, next time when probe the iomuxc, API devm_platform_ioremap_resource() will also use the API devm_request_mem_region() for the share region <0x30330000-0x3033ffff> again, then cause issue, log like below: [ 0.179561] imx7d-pinctrl 302c0000.iomuxc-lpsr: initialized IMX pinctrl driver [ 0.191742] imx7d-pinctrl 30330000.pinctrl: can't request region for resource [mem 0x30330000-0x3033ffff] [ 0.191842] imx7d-pinctrl: probe of 30330000.pinctrl failed with error -16 Fixes: ba403242615c ("pinctrl: freescale: imx: Use 'devm_of_iomap()' to avoid a resource leak in case of error in 'imx_pinctrl_probe()'") Signed-off-by: Haibo Chen <[email protected]> Reviewed-by: Dong Aisheng <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Linus Walleij <[email protected]>

2020-06-20afs: Fix hang on rmmod due to outstanding timerDavid Howells4-2/+16
The fileserver probe timer, net->fs_probe_timer, isn't cancelled when the kafs module is being removed and so the count it holds on net->servers_outstanding doesn't get dropped.. This causes rmmod to wait forever. The hung process shows a stack like: afs_purge_servers+0x1b5/0x23c [kafs] afs_net_exit+0x44/0x6e [kafs] ops_exit_list+0x72/0x93 unregister_pernet_operations+0x14c/0x1ba unregister_pernet_subsys+0x1d/0x2a afs_exit+0x29/0x6f [kafs] __do_sys_delete_module.isra.0+0x1a2/0x24b do_syscall_64+0x51/0x95 entry_SYSCALL_64_after_hwframe+0x44/0xa9 Fix this by: (1) Attempting to cancel the probe timer and, if successful, drop the count that the timer was holding. (2) Make the timer function just drop the count and not schedule the prober if the afs portion of net namespace is being destroyed. Also, whilst we're at it, make the following changes: (3) Initialise net->servers_outstanding to 1 and decrement it before waiting on it so that it doesn't generate wake up events by being decremented to 0 until we're cleaning up. (4) Switch the atomic_dec() on ->servers_outstanding for ->fs_timer in afs_purge_servers() to use the helper function for that.

2020-06-20afs: Fix afs_do_lookup() to call correct fetch-status op variantDavid Howells1-1/+1
Fix afs_do_lookup()'s fallback case for when FS.InlineBulkStatus isn't supported by the server. In the fallback, it calls FS.FetchStatus for the specific vnode it's meant to be looking up. Commit b6489a49f7b7 broke this by renaming one of the two identically-named afs_fetch_status_operation descriptors to something else so that one of them could be made non-static. The site that used the renamed one, however, wasn't renamed and didn't produce any warning because the other was declared in a header. Fix this by making afs_do_lookup() use the renamed variant. Note that there are two variants of the success method because one is called from ->lookup() where we may or may not have an inode, but can't call iget until after we've talked to the server - whereas the other is called from within iget where we have an inode, but it may or may not be initialised. The latter variant expects there to be an inode, but because it's being called from there former case, there might not be - resulting in an oops like the following: BUG: kernel NULL pointer dereference, address: 00000000000000b0 ...
