This patch adds logic to treat volatile virtual CD region as pmem
region, then /dev/pmem* device can be mounted with iso9660.
It's useful to work with the httpboot in EFI firmware to pull a remote

I also changed of_node_put(of_root) to of_node_put(np); both of them
hold the same pointer, but it seems better to call of_node_put()

The function compat_ptrace_request(used by ilp32) don't handle
{GET,SET}SIGMASK request, so it will be handled by ptrace_request.
But it's wrong because the compat_sigset_t of ilp32 differs from
the sigset_t of aarch64. The patch fixes it.

Hi Brian,
I haven't received more other comments for two weeks since I resent this
patch except a compiling error. Could you help me merge this patch into the

Certain instructions are hard to execute correctly out-of-line (as in
kprobes). Test functions are added to insn.[hc] to identify these. The

Add support for basic kernel probes(kprobes) and jump probes
(jprobes) for ARM64.
Kprobes utilizes software breakpoint and single step debug
exceptions supported on ARM v8.
A software breakpoint is placed at the probe address to trap the
kernel execution into the kprobe ha

The pre-handler of this special 'trampoline' kprobe executes the return
probe handler functions and restores original return address in ELR_EL1.
This way the saved pt_regs still hold the original register context to be
carried back to the probed kernel function.

From: William Cohen
The trampoline code is used by kretprobes to capture a return from a probed
function. This is done by saving the registers, calling the handler, and
restoring the registers. The code then returns to the original saved caller
return address. It is necessary to do this directly

Cease using the arm32 arm_check_condition() function and replace it with
a local version for use in deprecated instruction support on arm64. Also

and/or uprobes.
This function is derived from code writ

Kprobes needs simulation of instructions that cannot be stepped

that uses PC-relative addressing. In simulation, the behaviour
