Samples are documented to be available every 0.667us, so in theory
the 8 sample deep FIFO should take 5.336us to fill. However, during
thorough testing, it became apparent that filling the FIFO actually
takes closer to 12us.
Also take into consideration that udelay() can behave oddly i.e. not

well in my testing, so I'm hoping it's good.

Received handlers defined as ipmi_recv_hndl member of struct
ipmi_user_hndl can take a spinlock. This means that if the kernel
panics while holding the lock, a deadlock may happen on the lock
while flushing queued messages in the panic context.
Calling the receive handler doesn't make much meanings in the panic
context, simply skip it to avoid possible deadlocks.
Signed-off-by: Hidehiro Kawai <hidehiro.kawai.ez@hitachi.com>
Signed-off-by: Corey Minyard <cminyard@mvista.com>
When processing queued messages in the panic context, IPMI driver
tries to do it without any locking to avoid deadlocks. However,
this means we can touch a corrupted list if the kernel panicked
while manipulating the list. Fortunately, current `add-tail and
del-from-head' style implementation won't touch the corrupted part,
but it is inherently risky.
To get rid of the risk, this patch re-initializes the message lists
on panic if the related spinlock has already been acquired. As the
result, we may lose queued messages, but it's not so painful.
Dropping messages on the received message list is also less
problematic because no one can respond the received messages.

When flushing queued messages in run-to-completion mode,
smi_event_handler() is recursively called.
flush_messages()
smi_event_handler()
handle_transaction_done()
deliver_recv_msg()
ipmi_smi_msg_received()
smi_recv_tasklet()
sender()
flush_messages()
smi_event_handler()
...
The depth of the recursive call depends on the number of queued
messages, so it can cause a stack overflow if many messages have
been queued.
To solve this problem, this patch removes flush_messages()
from sender()@ipmi_si_intf.c. Instead, add flush_messages() to
caller side of sender() if needed. Additionally, to implement this,
add new handler flush_messages to struct ipmi_smi_handlers.

If the OPAL call to receive the ipmi message fails, then we free up the
smi message and return. But, the driver still holds the reference to
old smi message in the 'cur_msg' which can potentially be accessed later
and freed again leading to kernel oops. To fix it up,
The kernel driver should reset the 'cur_msg' and send reply to the user
in addition to freeing the message.

The IPMI SI driver was using direct PNP, but that was not really
ideal because the IPMI device is a platform device. There was
some special handling in the acpi_pnp.c code for making this work,
but that was breaking ACPI handling for the IPMI SSIF driver.
So without this patch there were significant issues getting the
SSIF driver to work with ACPI.
So use a platform device for ACPI detection and remove the
entry from acpi_pnp.c.

So stop pretending like it matters, and just return void from

drm/i915: Added BXT check in HAS_CORE_RING_FREQ macro
...
Backmerge fixes since it's getting out of hand again with the massive
split due to atomic between -next and 4.2-rc. All the bugfixes in
4.2-rc are addressed already (by converting more towards atomic
instead of minimal duct-tape) so just always pick the version in next
for the conflicts in modeset code.
All the other conflicts are just adjacent lines changed.
