Observe:

# Next command results in proper output

# Also works:

Some const'ification was done to simplify the actual solution of adding "-"
explicitly to the file list if we didn't have any file arguments left over.

cxgbe(4): Determine early in the ioctl whether it is allowed to sleep or
not, instead of always starting a non-sleepable operation and
re-adjusting later. This ensures that an operation that is allowed to

to start a synchronized operation.
This is a direct commit to stable/11. The driver ioctl is always

MFC r333667: followup to r332730/r332752: set kdb_why to "trap" for fatal traps
This change updates arm, arm64 and mips achitectures. Additionally, it
removes redundant checks for kdb_active where it already results in
kdb_reenter() and adds kdb_reenter() calls where they were missing.
Some architectures check the return value of kdb_trap(), but some don't.
I haven't changed any of that.
Some trap handling routines have a return code. I am not sure if I
provided correct ones for returns after kdb_reenter(). kdb_reenter
should never return unless kdb_jmpbufp is NULL for some reason.

MFC r333321,r333707: x86 cpususpend_handler: call wbinvd after setting suspend state bits
Without a subsequent wbinvd the changes to suspended_cpus (and
resuming_cpus) can be lost at least on AMD systems that use MOESI cache
coherency protocol. That can happen because one of APs ends up as an
Owner of the corresponding cache line(s) and the changes may never reach
the main memory before the AP is reset.
This change fixed suspend to RAM a previously broken AMD-based system.

MFC r332918, r333222: go deeper for ACPI suspend bounce test
debug.acpi.suspend_bounce sysctl now allows a deeper dive into the sleep
abyss. The system will execute the suspend sequence up to the call to
AcpiEnterSleepState(). That includes saving processor contexts and
parking APs. Then, instead of actually entering the sleep state, the
BSP will call resumectx() to emulate the wakeup. The APs should get
restarted by the sequence of Init and Startup IPIs that BSP sends to
them.
AcpiOsEnterSleep() is used to implement this feature.
