The uevents generated for an amba device need PID and CID information

Runtime resuming a device upfront in the genpd_prepare() callback, to check
if there is a wakeup pending for it, seems like an unnecessary thing to do.
The PM core already manages these kind of things in a common way in
__device_suspend(), via calling pm_runtime_barrier() and
pm_wakeup_pending().

If arch code calls the wrong kernel entry helpers, syscall entries and
exits can get out of sync. Add a new field to task_struct to track the
syscall state and validate that it transitions correctly.

exit_to_user_mode() does part, but not all, of the exit-to-user-mode work.
It's used only by arm64, and arm64 should stop using it (hint, hint!).
Compile it out on other architectures to minimize the chance of error.
enter_from_user_mode() is a legacy way to spell
kentry_enter_from_user_mode().
Calling instrumentation_begin() and instrumentation_end() when kentry
thinks the CPU is in user mode is an error. Verify the kentry state when
instrumentation_begin/end() are called.
Add _nocheck() variants to skip verification to avoid WARN() generating
extra kentry warnings.

In principle, the generic entry code is generic, and the goal is to use it
in many architectures once it settles down more. Move CONFIG_DEBUG_ENTRY
to the generic config so that it can be used in the generic entry code and
not just in arch/x86.
Disable it on arm64. arm64 uses some but not all
It's quite easy to mess up kentry calls. Add debgging checks that kentry
transitions to and from user mode match up and that kentry_nmi_enter() and
kentry_nmi_exit() match up.
Checking full matching of kentry_enter() with kentry_exit() needs
per-task state.

ret_from_fork is written in asm, slightly differently, for x86_32 and

This is a straight conversion without any particular cleverness. As a
further cleanup, the code that sets up the ret_from_fork argument registers
could be adjusted to put the arguments in the correct
The new common syscall API had a large and confusing API surface. Simplify
it. Now there is exactly one way to use it. It's a bit more verbose than
the old way for the simple x86_64 native case, but it's much easier to use

The common entry functions are mostly named irqentry, and this is
confusing. They are used for syscalls, exceptions, NMIs and, yes, IRQs.
Call them kentry instead, since they are supposed to be usable for any
entry to the kernel.
This path doesn't touch the .irqentry section -- someone can
I noticed a little bug in fast compat syscalls. I got a bit carried away
fixing it. This renames the irqentry stuff to kentry, improves (IMNSHO)
the API, and adds lots of debugging.
It also tweaks the unwinder wrt ret_from_fork and rewrites ret_from_fork
in C. I did this because the kentry
For kernel threads, task_pt_regs is currently all zeros, a valid user state
