In 2008, commit 0c5d1eb77a ("genirq: record trigger type") modified the
way set_irq_type() handles the 'no trigger' condition. However, this has
an adverse effect on PCMCIA support on Intel StrongARM and probably PXA
platforms.
PCMCIA has several status signals on the socket which can trigger
interrupts; some of these status signals depend on the card's mode
(whether it is configured in memory or IO mode). For example, cards have
a 'Ready/IRQ' signal: in memory mode, this provides an indication to
PCMCIA that the card has finished its power up initialization. In IO
mode, it provides the device interrupt signal. Other status signals
switch between on-board battery status and loud speaker output.
In classical PCMCIA implementations, where you have a specific socket
controller, the controller provides a method to mask interrupts from the
socket, and importantly ignore any state transitions on the pins which
correspond with interrupts once masked. This masking prevents unwanted
events caused by the removal and application of socket power being
forwarded.
However, on platforms where there is no socket controller, the PCMCIA
status and interrupt signals are routed to standard edge-triggered GPIOs.
These GPIOs can be configured to interrupt on rising edge, falling edge,
or never. This is where the problems start.
Edge triggered interrupts are required to record events while disabled via
the usual methods of {free,request,disable,enable}_irq() to prevent
problems with dropped interrupts (eg, the 8390 driver uses disable_irq()
to defer the delivery of interrupts). As a result, these interfaces can
not be used to implement the desired behaviour.
The side effect of this is that if the 'Ready/IRQ' GPIO is disabled via
disable_irq() on suspend, and enabled via enable_irq() after resume, we
will record the state transitions caused by powering events as valid
interrupts, and foward them to the card driver, which may attempt to
access a card which is not powered up.
This leads delays resume while drivers spin in their interrupt handlers,
and complaints from drivers before they realize what's happened.
Moreover, in the case of the 'Ready/IRQ' signal, this is requested and
freed by the card driver itself; the PCMCIA core has no idea whether the
interrupt is requested, and, therefore, whether a call to disable_irq()
would be valid. (We tried this around 2.4.17 / 2.5.1 kernel era, and
ended up throwing it out because of this problem.)
Therefore, it was decided back in around 2002 to disable the edge
triggering instead, resulting in all state transitions on the GPIO being
ignored. That's what we actually need the hardware to do.
The commit above changes this behaviour; it explicitly prevents the 'no
trigger' state being selected.
The reason that request_irq() does not accept the 'no trigger' state is
for compatibility with existing drivers which do not provide their desired
triggering configuration. The set_irq_type() function is 'new' and not
used by non-trigger aware drivers.
Therefore, revert this change, and restore previously working platforms
back to their former state.

wait_pending_extra_info_updates() currently does a hacky second check
for extra_info_update_ongoing() at the end of the function to show a
warning if extra_info update is still ongoing. The call to
extra_info_update_ongoing() should really be inside spinlock, but that's
a bit heavy just for verification.
Rather than that, check the return value of the
wait_for_completion_timeout() and print an error if it has timeouted or
returned an error.
Even better would be to return the error value and act on it in the
callers of wait_pending_extra_info_updates. However, it's not clear what
the callers should do in case of an error, as the error should only
happen if there's a bug in the driver or the HW. So we'll just print the
warning for now.

Fix a bug in kprobes which can modify kernel code
permanently at run-time. In the result, kernel can
crash when it executes the modified code.
This bug can happen when we put two probes enough near
and the first probe is optimized. When the second probe
is set up, it copies a byte which is already modified
by the first probe, and executes it when the probe is hit.
Even worse, the first probe and the second probe are removed
respectively, the second probe writes back the copied
(modified) instruction.
To fix this bug, kprobes always recovers the original
code and copies the first byte from recovered instruction.

Current probed-instruction recovery expects that only breakpoint
instruction modifies instruction. However, since kprobes jump
optimization can replace original instructions with a jump,
that expectation is not enough. And it may cause instruction
decoding failure on the function where an optimized probe
already exists.
This bug can reproduce easily as below:
1) find a target function address (any kprobe-able function is OK)
$ grep __secure_computing /proc/kallsyms
ffffffff810c19d0 T __secure_computing
2) decode the function
$ objdump -d vmlinux --start-address=0xffffffff810c19d0 --stop-address=0xffffffff810c19eb
vmlinux: file format elf64-x86-64
Disassembly of section .text:
ffffffff810c19d0 <__secure_computing>:
ffffffff810c19d0: 55 push %rbp
ffffffff810c19d1: 48 89 e5 mov %rsp,%rbp
ffffffff810c19d4: e8 67 8f 72 00 callq

ffffffff810c19e2: 83 b8 88 05 00 00 01 cmpl $0x1,0x588(%rax)
ffffffff810c19e9: 74 05 je ffffffff810c19f0 <__secure_computing+0x20>
3) put a kprobe-event at an optimize-able place, where no
call/jump places within the 5 bytes.
$ su -
# cd /sys/kernel/debug/tracing
# echo p __secure_computing+0x9 > kprobe_events
4) enable it and check it is optimized.
# echo 1 > events/kprobes/p___secure_computing_9/enable
# cat ../kprobes/list
ffffffff810c19d9 k __secure_computing+0x9 [OPTIMIZED]
5) put another kprobe on an instruction after previous probe in
the same function.
# echo p __secure_computing+0x12 >> kprobe_events
bash: echo: write error: Invalid argument
# dmesg | tail -n 1
[ 1666.500016] Probing address(0xffffffff810c19e2) is not an instruction boundary.
6) however, if the kprobes optimization is disabled, it works.
# echo 0 > /proc/sys/debug/kprobes-optimization
# cat ../kprobes/list
ffffffff810c19d9 k __secure_computing+0x9
# echo p __secure_computing+0x12 >> kprobe_events
(no error)
This is because kprobes doesn't recover the instruction
which is overwritten with a relative jump by another kprobe
when finding instruction boundary.
It only recovers the breakpoint instruction.
This patch fixes kprobes to recover such instructions.
With this fix:
# echo p __secure_computing+0x9 > kprobe_events
# echo 1 > events/kprobes/p___secure_computing_9/enable
# cat ../kprobes/list
ffffffff810c1aa9 k __secure_computing+0x9 [OPTIMIZED]
# echo p __secure_computing+0x12 >> kprobe_events
# cat ../kprobes/list
ffffffff810c1aa9 k __secure_computing+0x9 [OPTIMIZED]
ffffffff810c1ab2 k __secure_computing+0x12 [DISABLED]

- Fix a bug to ensure optimized probe is really optimized
by jump.
- Remove kprobe_optready() dependency.
- Cleanup code for preparing optprobe separation.

- Fix a build error when CONFIG_OPTPROBE=n. (Thanks, Ingo!)

Intel MSIC MFD driver provides common register access interface
to the devices in the MSIC die so we use that instead of SCU
IPC.

All the production devices use the PC compatible version of this
device so don't use the SCU interfaces or the SCU firmware
interfaces.
Delete lots of code and conditional paths

All production devices operate in the Oaktrail configuration
with legacy PC elements present and an ACPI BIOS. Continue
stripping out the Moorestown elements from the tree leaving
Medfield.

The number of IOMMUs supported should be the same as the number
of IO APICS. This limit comes into play when the IOMMUs are
identity mapped, thus the number of possible IOMMUs in the
"static identity" (si) domain should be this same number.
