Pull syscall numbering updates from Arnd Bergmann: "arch: add pidfd and io_uring syscalls everywhere This comes a bit late, but should be in 5.1 anyway: we want the newly added system calls to be synchronized across all architectures in the release. I hope that in the future, any newly added system calls can be added to all architectures at the same time, and tested there while they are in linux-next, avoiding dependencies between the architecture maintainer trees and the tree that contains the new system call" * tag 'syscalls-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: arch: add pidfd and io_uring syscalls everywhere

arch: add pidfd and io_uring syscalls everywhere

2019-04-15T14:31:17Z

Add the io_uring and pidfd_send_signal system calls to all architectures. These system calls are designed to handle both native and compat tasks, so all entries are the same across architectures, only arm-compat and the generic tale still use an old format.

parisc: Detect QEMU earlier in boot process

2019-04-06T17:07:55Z

While adding LASI support to QEMU, I noticed that the QEMU detection in the kernel happens much too late. For example, when a LASI chip is found by the kernel, it registers the LASI LED driver as well. But when we run on QEMU it makes sense to avoid spending unnecessary CPU cycles, so we need to access the running_on_QEMU flag earlier than before. This patch now makes the QEMU detection the fist task of the Linux kernel by moving it to where the kernel enters the C-coding.

parisc: Show machine product number during boot

2019-02-21T19:37:13Z

Ask PDC firmware during boot for the original and current product number as well as the serial number and show it (if available). Signed-off-by: Helge Deller

No need for any of the definitions here, all there real work now happens out of line. Signed-off-by: Christoph Hellwig Signed-off-by: Helge Deller

parisc: replace oops_in_progress manipulation with bust_spinlocks()

Use bust_spinlocks() function to set oops_in_progress. Signed-off-by: Sergey Senozhatsky Signed-off-by: Helge Deller

parisc: Improve initial IRQ to CPU assignment

2019-02-21T19:37:11Z

On parisc, each IRQ can only be handled by one CPU, and currently CPU0 is choosen as default for handling all IRQs by default. With this patch we now assign each requested IRQ to one of the online CPUs (and thus distribute the IRQs across all CPUs), even without an instance of irqbalance running. Signed-off-by: Helge Deller

parisc: Count IPI function call interrupts

2019-02-21T19:37:11Z

Like other platforms, count the number of IPI function call interrupts and show it in /proc/interrupts. Signed-off-by: Helge Deller
