I took it back in 4.13. Now he realizes that he had a mistake, and swapped the values from what Android had. This means that the old Android tools will break when using a new kernel that has the new feature on it. The options are: 1. To swap it back to what Android wants. 2. Add a command line option or something to do the swap 3. Just let Android carry a patch that swaps it back Since it requires setting a tracing option to enable this anyway, I doubt there are other users of this than Android. Thus, I've decided to take option 1. If someone else is actually depending on the order that is in the kernel, then we will have to revert this change and go to option 2 or 3" * tag 'trace-v4.18-rc3-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Reorder display of TGID to be after PID

2018-07-13xen: setup pv irq ops vector earlierJuergen Gross
Setting pv_irq_ops for Xen PV domains should be done as early as possible in order to support e.g. very early printk() usage. The same applies to xen_vcpu_info_reset(0), as it is needed for the pv irq ops. Move the call of xen_setup_machphys_mapping() after initializing the pv functions as it contains a WARN_ON(), too. Remove the no longer necessary conditional in xen_init_irq_ops() from PVH V1 times to make clear this is a PV only function.

2018-07-12tracing: Reorder display of TGID to be after PIDJoel Fernandes (Google)
Currently ftrace displays data in trace output like so: _-----=> irqs-off / _----=> need-resched | / _---=> hardirq/softirq || / _--=> preempt-depth ||| / delay TASK-PID CPU TGID |||| TIMESTAMP FUNCTION | | | | |||| | | bash-1091 [000] ( 1091) d..2 28.313544: sched_switch: However Android's trace visualization tools expect a slightly different format due to an out-of-tree patch patch that was been carried for a decade, notice that the TGID and CPU fields are reversed: _-----=> irqs-off / _----=> need-resched | / _---=> hardirq/softirq || / _--=> preempt-depth ||| / delay TASK-PID TGID CPU |||| TIMESTAMP FUNCTION | | | | |||| | | bash-1091 ( 1091) [002] d..2 64.965177: sched_switch: From kernel v4.13 onwards, during which TGID was introduced, tracing with systrace on all Android kernels will break (most Android kernels have been on 4.9 with Android patches, so this issues hasn't been seen yet). From v4.13 onwards things will break. The chrome browser's tracing tools also embed the systrace viewer which uses the legacy TGID format and updates to that are known to be difficult to make. Considering this, I suggest we make this change to the upstream kernel and backport it to all Android kernels. I believe this feature is merged recently enough into the upstream kernel that it shouldn't be a problem. Also logically, IMO it makes more sense to group the TGID with the TASK-PID and the CPU after these.

2018-07-12extcon: int3496: Use proper GPIO includeWolfram Sang
Since commit eca0f13c836a ("extcon: int3496: Ignore incorrect IoRestriction for ID pin"), the driver doesn't use GPIOF_* flags anymore. We can thus now drop the deprecated include file for GPIO and use the new one. Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
2018-07-11ARM: 8780/1: ftrace: Only set kernel memory back to read-only after bootSteven Rostedt (VMware)
Dynamic ftrace requires modifying the code segments that are usually set to read-only. To do this, a per arch function is called both before and after the ftrace modifications are performed. The "before" function will set kernel code text to read-write to allow for ftrace to make the modifications, and the "after" function will set the kernel code text back to "read-only" to keep the kernel code text protected. The issue happens when dynamic ftrace is tested at boot up. The test is done before the kernel code text has been set to read-only. But the "before" and "after" calls are still performed. The "after" call will change the kernel code text to read-only prematurely, and other boot code that expects this code to be read-write will fail. The solution is to add a variable that is set when the kernel code text is expected to be converted to read-only, and make the ftrace "before" and "after" calls do nothing if that variable is not yet set. This is similar to the x86 solution from commit 162396309745 ("ftrace, x86: make kernel text writable only for conversions").
