no functional change -- cleanup only.
acpi_processor_power_verify_c2() was nearly empty due to a previous patch,
so expand its remains into its one caller and delete it.

Do for C3 what the previous patch did for C2.
The C2 patch was in response to a highly visible
and multiply reported C-state/turbo failure,
while this change has no bug report in-hand.
This will enable C3 in Linux on systems where BIOS
overstates C3 latency in _CST. It will also enable
future systems which may actually have C3 > 1000usec.
Linux has always ignored ACPI BIOS C3 with exit latency > 1000 usec,
and the ACPI spec is clear that is correct FADT-supplied C3.
However, the ACPI spec explicitly states that _CST-supplied C-states
have no latency limits.
So move the 1000usec C3 test out of the code shared
by FADT and _CST code-paths, and into the FADT-specific path.

So move the 100usec C2 test out of the code shared

This bug has not been visible until Nehalem, which advertises
a CPU-C2 worst case exit latency on servers of 205usec.
That (incorrect) figure is being used by BIOS writers
on mobile Nehalem systems for the AC configuration.
Thus, Linux ignores C2 leaving just C1, which is
saves less power, and also impacts performance
by preventing the use of turbo mode.

[WATCHDOG] iTCO_wdt: Add Intel Cougar Point and PCH DeviceIDs
|
|
We can use logical flat mode if there are <= 8 logical cpu's
(irrespective of physical apic id values). This will enable simplified
and efficient IPI and device interrupt routing on such platforms.
This has been tested to work on both Intel and AMD platforms.
Exceptions like IBM summit platform which can't use logical flat mode
are addressed by using OEM platform checks.

Chris McDermott from IBM confirmed that hurricane chipset in IBM summit
platforms doesn't support logical flat mode. Irrespective of the other
things like apic_id's, total number of logical cpu's, Linux kernel
should default to physical mode for this system.
The 32-bit kernel does so using the OEM checks for the IBM summit
platform. Add a similar OEM platform check for the 64bit kernel too.
Otherwise the linux kernel boot can hang on this platform under certain
bios/platform settings.

When a card instance with a higher card number is registered, warning
messages are spewed eventually with stack traces due to the invalid minor
number for OSS device registration. For example, thinkpad-acpi registers
the card number 29 as default, and you'll see always these messages.
This is rather confusing (and worries users), thus better to return
simply the error code.

The sym_is() compares a symbol in an attempt to automatically skip symbol
prefixes. It does this first by searching the real symbol with the normal
unprefixed symbol. But then it uses the length of the original symbol to
check the end of the substring instead of the length of the symbol it is
looking for. On non-prefixed arches, this is effectively the same thing,
so there is no problem. On prefixed-arches, since this is exceeds by just
one byte, a crash is rare and it is usually a NUL byte anyways. But every
once in a blue moon, you get the right page alignment and it segfaults.
For example, on the Blackfin arch, sym_is() will be called with the real
symbol "___mod_usb_device_table" as "symbol" when looking for the normal
symbol "__mod_usb_device_table" as "name". The substring will thus return
one byte into "symbol" and store it into "match". But then "match" will
be indexed with the length of "symbol" instead of "name" and so we will
exceed the storage. i.e. the code ends up doing:
char foo[] = "abc"; return foo[strlen(foo)+1] == '\0';
