staging: comedi: addi_apci_3xxx: fix the analog input subdevice
The analog input subdevice support functions in hwdrv_apci3xxx.c
do not follow the comedi API.
The (*insn_config) function overrides the INSN_CONFIG_DIO_INPUT
instruction as an internal APCI3XXX_CONFIGURATION instruction. The
APCI3XXX_CONFIGURATION instruction requires 4 data parameters but
the comedi core sanity checks the INSN_CONFIG_DIO_INPUT instruction
which only has 1 data parameter. Because of this the (*insn_config)
function can never be called.
The (*insn_read) function is supposed to do "one-shot" or "software-
triggered" reads and return the data. The function in hwdrv_apci3xxx.c
does do this but it also is used to optionally start a "hardware-
triggered" conversion. Hardware-triggered conversions should be done
with the comedi_async command functions.
Delete the hwrdv_apci3xxx.c file and fix the analog input subdevice
in the driver by:
1) add a new (*insn_read) function for "one-shot" reads
2) implement the (*do_cmdtest) and (*do_cmd) functions for
"hardware-triggered" asyncronous reads
3) fix the interrupt handler to return the read data via the
comedi_async buffer

staging: comedi: addi_apci_3xxx: refactor the ttl digital i/o support
Currently, the subdevice functions used to configure and read/write the
ttl digital i/o ports is way over to complicated. The (*insn_config)
function also abuses the comedi API by overriding the instruction
command passed in data[0].
Fix the ttl digital i/o support to work like the comedi core expects.
The (*insn_config) function supports the three instructions common for
COMEDI_SUBD_DIO subdevices:
INSN_CONFIG_DIO_INPUT - configure the specified channel as input
INSN_CONFIG_DIO_OUTPUT - configure the specified channel as output
INSN_CONFIG_DIO_QUERY - returns the status of the specified channel
Port 0 (channels 0-7) is always input
Port 1 (channels 8-15) is always output
Port 2 (channels 9-23) are programmable i/o (all channels are input or output)
The (*insn_bits) function allows writing to the output channels and returns
the state of all channels.
The (*insn_read) and (*insn_write) functions are not required. The comedi
core will emulate them using the (*insn_bits) function.

It will be shortly and as no one actually uses this chip with that

smp.h: Use local_irq_{save,restore}() in !SMP version of on_each_cpu().
Thanks to commit
f91eb62f71b3 ("init: scream bloody murder if interrupts
are enabled too early"), "bloody murder" is now being screamed.
With a MIPS OCTEON config, we use on_each_cpu() in our
irq_chip.irq_bus_sync_unlock() function. This gets called in early as a
result of the time_init() call. Because the !SMP version of
on_each_cpu() unconditionally enables irqs, we get:
WARNING: at init/main.c:560 start_kernel+0x250/0x410()
Interrupts were enabled early
CPU: 0 PID: 0 Comm: swapper Not tainted 3.10.0-rc5-Cavium-Octeon+ #801
Call Trace:

warn_slowpath_common+0x78/0xb0
warn_slowpath_fmt+0x38/0x48
start_kernel+0x250/0x410
Suggested fix: Do what we already do in the SMP version of
on_each_cpu(), and use local_irq_save/local_irq_restore. Because we
need a flags variable, make it a static inline to avoid name space
issues.
[ Change from v1: Convert on_each_cpu to a static inline function, add
#include <linux/irqflags.h> to avoid build breakage on some files.
on_each_cpu_mask() and on_each_cpu_cond() suffer the same problem as
on_each_cpu(), but they are not causing !SMP bugs for me, so I will
defer changing them to a less urgent patch. ]

powerpc: Fix missing/delayed calls to irq_work
When replaying interrupts (as a result of the interrupt occurring
while soft-disabled), in the case of the decrementer, we are exclusively
testing for a pending timer target. However we also use decrementer
interrupts to trigger the new "irq_work", which in this case would
be missed.
This change the logic to force a replay in both cases of a timer
boundary reached and a decrementer interrupt having actually occurred
while disabled. The former test is still useful to catch cases where
a CPU having been hard-disabled for a long time completely misses the
interrupt due to a decrementer rollover.

powerpc: Fix emulation of illegal instructions on PowerNV platform
Normally, the kernel emulates a few instructions that are unimplemented
on some processors (e.g. the old dcba instruction), or privileged (e.g.
mfpvr). The emulation of unimplemented instructions is currently not
working on the PowerNV platform. The reason is that on these machines,
unimplemented and illegal instructions cause a hypervisor emulation
assist interrupt, rather than a program interrupt as on older CPUs.
Our vector for the emulation assist interrupt just calls
program_check_exception() directly, without setting the bit in SRR1
that indicates an illegal instruction interrupt. This fixes it by
making the emulation assist interrupt set that bit before calling
program_check_interrupt(). With this, old programs that use no-longer
implemented instructions such as dcba now work again.

... and so on
__ppc64_runlatch_on() is called from RUNLATCH_ON in the exception entry
path. At that point the irq state is not consistent, ie. interrupts are
hard disabled (by the exception entry), but the paca soft-enabled flag
may be out of sync.
This leads to the local_irq_restore() in trace_graph_entry() actually
enabling interrupts, which we do not want. Because we have not yet
reprogrammed the decrementer we immediately take another decrementer
exception, and recurse.
The fix is twofold. Firstly make sure we call DISABLE_INTS before
calling RUNLATCH_ON. The badly named DISABLE_INTS actually reconciles
the irq state in the paca with the hardware, making it safe again to
call local_irq_save/restore().
Although that should be sufficient to fix the bug, we also mark the
runlatch routines as notrace. They are called very early in the
exception entry and we are asking for trouble tracing them. They are
also fairly uninteresting and tracing them just adds unnecessary
overhead.

move exit_task_namespaces() outside of exit_notify()
exit_notify() does exit_task_namespaces() after
forget_original_parent(). This was needed to ensure that ->nsproxy
can't be cleared prematurely, an exiting child we are going to
reparent can do do_notify_parent() and use the parent's (ours) pid_ns.
However, after
32084504 "pidns: use task_active_pid_ns in
do_notify_parent" ->nsproxy != NULL is no longer needed, we rely
on task_active_pid_ns().
Move exit_task_namespaces() from exit_notify() to do_exit(), after
exit_fs() and before exit_task_work().
This solves the problem reported by Andrey, free_ipc_ns()->shm_destroy()
does fput() which needs task_work_add().
Note: this particular problem can be fixed if we change fput(), and
that change makes sense anyway. But there is another reason to move
the callsite. The original reason for exit_task_namespaces() from
the middle of exit_notify() was subtle and it has already gone away,
now this looks confusing. And this allows us do simplify exit_notify(),
we can avoid unlock/lock(tasklist) and we can use ->exit_state instead
of PF_EXITING in forget_original_parent().
