ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f This patch removes unwanted spaces for typedef. This solution doesn't cover function types. Note that the linuxize result of this commit is very giant and should have many conflicts against the current Linux upstream. Thus it is required to modify the linuxize result of this commit and the commits around it manually in order to have them merged to the Linux upstream. Since this is very costy, we should do this only once, and if we can't ensure to do this only once, we need to revert the Linux code to the wrong indentation result before merging the linuxize result of this commit.

/******************************************************************************
|
|
*
|
|
* ACPICA policy for new _OSI strings:
|
|
*
|
|
* It is the stated policy of ACPICA that new _OSI strings will be integrated
|
|
* into this module as soon as possible after they are defined. It is strongly
|
|
* recommended that all ACPICA hosts mirror this policy and integrate any
|
|
* changes to this module as soon as possible. There are several historical
|
|
* reasons behind this policy:
|
|
*
|
|
* 1) New BIOSs tend to test only the case where the host responds TRUE to
|
|
* the latest version of Windows, which would respond to the latest/newest
|
|
* _OSI string. Not responding TRUE to the latest version of Windows will
|
|
* risk executing untested code paths throughout the DSDT and SSDTs.
|
|
*
|
|
* 2) If a new _OSI string is recognized only after a significant delay, this
|
|
* has the potential to cause problems on existing working machines because
|
|
* of the possibility that a new and different path through the ASL code
|
|
* will be executed.
|
|
*
|
|
* 3) New _OSI strings are tending to come out about once per year. A delay
|
|
* in recognizing a new string for a significant amount of time risks the
|
|
* release of another string which only compounds the initial problem.
|
|
*

|
|
*
|
|
* March 2009: Removed "Linux" as this host no longer wants to respond true
|
|
* for this string. Basically, the only safe OS strings are windows-related
|
|
* and in many or most cases represent the only test path within the
|
|
* BIOS-provided ASL code.
|
