The x86_64 int3 handler adds a small gap to allow the stack to grow some. Use this gap to add the return address to be able to emulate a call instruction at the breakpoint location. These helper functions are added: int3_emulate_jmp(): changes the location of the regs->ip to return there. (The next two are only for x86_64) int3_emulate_push(): to push the address onto the gap in the stack int3_emulate_call(): push the return address and change regs->ip Cc: Andy Lutomirski <luto(a)kernel.org> Cc: Nicolai Stange <nstange(a)suse.de> Cc: Thomas Gleixner <tglx(a)linutronix.de> Cc: Ingo Molnar <mingo(a)redhat.com> Cc: Borislav Petkov <bp(a)alien8.de> Cc: "H.

The patch below does not apply to the 4.19-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From b79656ed44c6865e17bcd93472ec39488bcc4984 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky <leonro(a)mellanox.com> Date: Mon, 6 May 2019 14:23:04 +0300 Subject: [PATCH] RDMA/ipoib: Allow user space differentiate between valid dev_port Systemd triggers the following warning during IPoIB device load: mlx5_core 0000:00:0c.0 ib0: "systemd-udevd" wants to know my dev_id. Should it look at dev_port instead? See Documentation/ABI/testing/sysfs-class-net for more info. This is caused due to user space attempt to differentiate old systems without dev_port and new systems with dev_port. In case dev_port will be zero, the systemd will try to read dev_id instead. There is no need to print a warning in such case, because it is valid situation and it is needed to ensure systemd compatibility with old kernels.

FAILED: patch "[PATCH] media: imx: Don't register IPU subdevs/links if CSI port" failed to apply to 5.0-stable tree

The patch below does not apply to the 5.0-stable tree.

This is wrong for i.MX6 S/DL and i.MX53 which have only a single IPU.
