Jes Sorensen 43cc672518 [IA64-SGI] cleanup shubio.h 
This patch cleans up include/asm/sn/shubio.h by removing a ton of
whitespaces and running it through Lindent, reducing it's size by almost
30KB. No actual content has been changed.

* Description: This register's value is a bit vector that guards *

* four nodes (depending on the value of the REGION_SIZE field in the *
* LB_REV_ID register, which is documented in Section 8.3.1.1). The *
* protection provided by this register applies to PIO read *
* operations as well as PIO write operations. The II will perform a *
* PIO read or write request only if the bit for the requestor's *
* region is set; otherwise, the II will not perform the requested *
* operation and will return an error response. When a PIO read or *
* write request targets an external Crosstalk widget, then not only *
* must the bit for the requestor's region be set in the ILAPR, but *
* also the target widget's bit in the IOWA register must be set in *
* order for the II to perform the requested operation; otherwise, *
* the II will return an error response. Hence, the protection *
* provided by the IOWA register supplements the protection provided *
* by the ILAPR for requests that target external Crosstalk widgets. *
* This register itself can be accessed only by the nodes whose *
* region ID bits are enabled in this same register. It can also be *
* accessed through the IAlias space by the local processors. *
