acpigen_write_uuid() will generate a ToUUID() 128-bit buffer object for a
common universally unique identifier that is passed as a string. The
resulting buffer is the UUID in byte format with a specific order of the
bytes as described in the ACPI specification:
ToUUID (uuid)
Compiles to:
Buffer (16) { uuid[3], uuid[2], uuid[1], uuid[0], uuid[5], uuid[4],
uuid[7], uuid[6], uuid[8], uuid[9], uuid[10], uuid[11],
uuid[12], uuid[13], uuid[14], uuid[15] }

strlen(string) was on the "negative" side of the selection operator, the
side where string is NULL.

Add helper functions for generating some common objects:
acpigen_write_STA(status) will generate a status method that will
indicate the device status as provided:
Method (_STA) { Return (status) }
Full status byte configuration is possible and macros are provided for
the common status bytes used for generated code:
ACPI_STATUS_DEVICE_ALL_OFF = 0x0
ACPI_STATUS_DEVICE_ALL_ON = 0xF
acpigen_write_PRW() will generate a Power Resoruce for Wake that describes
the GPE that will wake a particular device:
Name (_PRW, Package (2) { wake, level }

In order to produce smaller AML and not rely on the caller to size the
output type appropriately add a helper function that will output an
appropriately sized integer.
To complete this also add helper functions for outputting the single
OpCode for Zero and One and Ones.
And finally add "name" variants of the helpers that will output a
complete sequence like "Name (_UID, Zero)".

Add helper function to emit a string into the SSDT AML bytestream with a
NULL terminator. Also add a helper function to emit the string OpCode
followed by the string itself.
acpigen_emit_string(string) /* Raw string output */
acpigen_write_string(string) /* OpCode followed by raw string */

Add helpers for writing word and dword values in acpigen and use them
throughout the file to clean things up:
acpigen_emit_word - write raw word
acpigen_emit_dword - write raw dword
acpigen_write_word - write word opcode and value

This patch adds CC6 power save support to the AMD Family 15h
support code. As CC6 is a complex power saving state that
relies heavily on CPU, northbridge, and southbridge cooperation,
this patch alters significant amounts of code throughout the
tree simultaneously.
Allowing the CPU to enter CC6 allows the second level of turbo
boost to be reached, and also provides significant power savings
when the system is idle due to the complete core shutdown.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

It never made sense to have bootblock_* in init, but
pirq_routing.c in boot, and some ld scripts on the main
level while others live in subdirectories.
This patch flattens the directory hierarchy and makes
x86 more similar to the other architectures.
