2020-01-08usb: musb: fix idling for suspend after disconnect interruptTony Lindgren
When disconnected as USB B-device, suspend interrupt should come before diconnect interrupt, because the DP/DM pins are shorter than the VBUS/GND pins on the USB connectors. But we sometimes get a suspend interrupt after disconnect interrupt. In that case we have devctl set to 99 with VBUS still valid and musb_pm_runtime_check_session() wrongly thinks we have an active session. We have no other interrupts after disconnect coming in this case at least with the omap2430 glue. Let's fix the issue by checking the interrupt status again with delayed work for the devctl 99 case. In the suspend after disconnect case the devctl session bit has cleared by then and musb can idle. For a typical USB B-device connect case we just continue with normal interrupts.

2020-01-08btrfs: fix invalid removal of root refJosef Bacik
If we have the following sequence of events btrfs sub create A btrfs sub create A/B btrfs sub snap A C mkdir C/foo mv A/B C/foo rm -rf * We will end up with a transaction abort. The reason for this is because we create a root ref for B pointing to A. When we create a snapshot of C we still have B in our tree, but because the root ref points to A and not C we will make it appear to be empty. The problem happens when we move B into C. This removes the root ref for B pointing to A and adds a ref of B pointing to C. When we rmdir C we'll see that we have a ref to our root and remove the root ref, despite not actually matching our reference name. Now btrfs_del_root_ref() allowing this to work is a bug as well, however we know that this inode does not actually point to a root ref in the first place, so we shouldn't be calling btrfs_del_root_ref() in the first place and instead simply look up our dir index for this item and do the rest of the removal.

2020-01-08arm64: asm: Add new-style position independent function annotationsMark Brown
As part of an effort to make the annotations in assembly code clearer and more consistent new macros have been introduced, including replacements for ENTRY() and ENDPROC(). On arm64 we have ENDPIPROC(), a custom version of ENDPROC() which is used for code that will need to run in position independent environments like EFI, it creates an alias for the function with the prefix __pi_ and then emits the standard ENDPROC. Add new-style macros to replace this which expand to the standard SYM_FUNC_*() and SYM_FUNC_ALIAS_*(), resulting in the same object code. These are added in linkage.h for consistency with where the generic assembler code has its macros.
