When the imux entries are rebuilt in alc_rebuild_imux_for_auto_mic(),
the initialization of index field is missing. It may work without it
casually when the original imux was created by the auto-parser, but
it's definitely broken in the case of static configs where no imux was
parsed beforehand. Because of this, the auto-mic switching doesn't
work properly on some model options.
This patch adds the missing initialization of index field.

The PCI SSID 8086:7270 is commonly used for multiple Apple machines,
thus we can't use it as identifier for a unique model. Because of this
conflict, some machines show weird behavior. For example, MacBook Air
shows Front and Surround speakers although only Surround works due to
the wrongly overridden pin-configuration for imac27.
This patch fixes two things:
- Stop the wrong pin-config override of imac27 by removing PCI SSID
entry for avoiding the wrong mappings,
- Add the generic GPIO setup for Apple machines by checking the codec
SSID vendor bits

This reverts commit dc93728084.
As requested by Ben Herrenschmidt:
"This breaks some powerpc platforms at least. The practice of having
a node provide an explicit "interrupt-parent" property pointing to
itself is an old trick that we've used in the past to allow a
device-node to have interrupts routed to different controllers.
In that case, the node also contains an interrupt-map, so the node is
its own parent, the interrupt resolution hits the map, which then can
route each individual interrupt to a different parent."
Grant says:
"Ah, nuts, yes that is broken then. Yes, please revert the commit and
Rob & I will come up with a better solution.
Rob, I think it can be done by explicitly checking for np ==
desc->interrupt_parent in of_irq_init() instead of relying on
of_irq_find_parent() returning NULL."

By returning '0' instead of 'EAGAIN' when the tests in xs_nospace() fail
to find evidence of socket congestion, we are making the RPC engine believe
that the message was incorrectly sent and so it disconnects the socket
instead of just retrying.
The bug appears to have been introduced by commit
5e3771ce2d (SUNRPC: Ensure that xs_nospace
return values are propagated).

Attempting to use a hardware counter on a platform with a supported PMU

Percpu allocator recorded the cpus which map to the first and last
units in pcpu_first/last_unit_cpu respectively and used them to
determine the address range of a chunk - e.g. it assumed that the
first unit has the lowest address in a chunk while the last unit has
the highest address.
This simply isn't true. Groups in a chunk can have arbitrary positive
or negative offsets from the previous one and there is no guarantee
that the first unit occupies the lowest offset while the last one the
highest.
Fix it by actually comparing unit offsets to determine cpus occupying
the lowest and highest offsets. Also, rename pcu_first/last_unit_cpu
to pcpu_low/high_unit_cpu to avoid confusion.
The chunk address range is used to flush cache on vmalloc area
map/unmap and decide whether a given address is in the first chunk by
per_cpu_ptr_to_phys() and the bug was discovered by invalid
per_cpu_ptr_to_phys() translation for crash_note.
