2019-01-03arm64: entry: remove unused register aliasesMark Rutland
In commit: 3b7142752e4bee15 ("arm64: convert native/compat syscall entry to C") ... we moved the syscall invocation code from assembly to C, but left behind a number of register aliases which are now unused. Let's remove them before they confuse someone.

2019-01-03perf stat: Fix endless wait for child processJin Yao
We hit a 'perf stat' issue by using following script: #!/bin/bash sleep 1000 & exec perf stat -a -e cycles -I1000 -- sleep 5 Since "perf stat" is launched by exec, the "sleep 1000" would be the child process of "perf stat". The wait4() call will not return because it's waiting for the child process "sleep 1000" to end. So 'perf stat' doesn't return even after 5s passes. This patch lets 'perf stat' return when the specified child process ends (in this case, the specified child process is "sleep 5").

2019-01-03mfd: tps6586x: Handle interrupts on suspendJonathan Hunter
The tps6586x driver creates an irqchip that is used by its various child devices for managing interrupts. The tps6586x-rtc device is one of its children that uses the tps6586x irqchip. When using the tps6586x-rtc as a wake-up device from suspend, the following is seen: PM: Syncing filesystems ... done. Freezing user space processes ... (elapsed 0.001 seconds) done. OOM killer disabled. Freezing remaining freezable tasks ... (elapsed 0.000 seconds) done. Disabling non-boot CPUs ... Entering suspend state LP1 Enabling non-boot CPUs ... CPU1 is up tps6586x 3-0034: failed to read interrupt status tps6586x 3-0034: failed to read interrupt status The reason why the tps6586x interrupt status cannot be read is because the tps6586x interrupt is not masked during suspend and when the tps6586x-rtc interrupt occurs, to wake-up the device, the interrupt is seen before the i2c controller has been resumed in order to read the tps6586x interrupt status. The tps6586x-rtc driver sets it's interrupt as a wake-up source during suspend, which gets propagated to the parent tps6586x interrupt. However, the tps6586x-rtc driver cannot disable it's interrupt during suspend otherwise we would never be woken up and so the tps6586x must disable it's interrupt instead. Prevent the tps6586x interrupt handler from executing on exiting suspend before the i2c controller has been resumed by disabling the tps6586x interrupt on entering suspend and re-enabling it on resuming from suspend.

2019-01-03mfd: ab8500-core: Return zero in get_register_interruptible()Dan Carpenter
This function is supposed to return zero on success or negative error codes on error. Unfortunately, there is a bug so it sometimes returns non-zero, positive numbers on success. I noticed this bug during review and I can't test it. It does appear that the return is sometimes propogated back to _regmap_read() where all non-zero returns are treated as failure so this may affect run time.

If the PMIC ID is unknown, the current code would call irq_domain_remove and panic, as pmic->irq_domain is only initialized by mt6397_irq_init.

When building the kernel with Clang, the following section mismatch warnings appear: WARNING: vmlinux.o(.text+0x7239cc): Section mismatch in reference from the function db8500_prcmu_probe() to the function .init.text:init_prcm_registers() The function db8500_prcmu_probe() references the function __init init_prcm_registers(). This is often because db8500_prcmu_probe lacks a __init annotation or the annotation of init_prcm_registers is wrong. WARNING: vmlinux.o(.text+0x723e28): Section mismatch in reference from the function db8500_prcmu_probe() to the function .init.text:fw_project_name() The function db8500_prcmu_probe() references the function __init fw_project_name(). This is often because db8500_prcmu_probe lacks a __init annotation or the annotation of fw_project_name is wrong. db8500_prcmu_probe should not be marked as __init so remove the __init annotation from fw_project_name and init_prcm_registers.

2019-01-02ipv6: Consider sk_bound_dev_if when binding a socket to an addressDavid Ahern
IPv6 does not consider if the socket is bound to a device when binding to an address. The result is that a socket can be bound to eth0 and then bound to the address of eth1. If the device is a VRF, the result is that a socket can only be bound to an address in the default VRF. Resolve by considering the device if sk_bound_dev_if is set.

2019-01-02ipv6: Fix dump of specific table with strict checkingDavid Ahern
Dump of a specific table with strict checking enabled is looping. The problem is that the end of the table dump is not marked in the cb. When dumping a specific table, cb args 0 and 1 are not used (they are the hash index and entry with an hash table index when dumping all tables). Re-use args[0] to hold a 'done' flag for the specific table dump.
