FUJITA Tomonori d8d54b0252 [IA64] remove dead BIO_VMERGE_BOUNDARY definition
The block layer dropped the virtual merge feature
(b8b3e16cfe). BIO_VMERGE_BOUNDARY
definition is meaningless now (For IA64, BIO_VMERGE_BOUNDARY has been
meaningless for a long time since IA64 disables the virtual merge
feature).

James Bottomley 8a549f8b58 [IA64] Fix __{in,out}s{w,l} to handle unaligned data
Some ia64 systems produce several repeats of kernel messages like this:

 kernel unaligned access to 0xe000000644220466, ip=0xa000000100516fa1

This was tracked to ide code using the __cmd[] field in "struct request"
via the __outsw() function.  __cmd[] is a char array, so is not guaranteed
to be properly aligned when accessed as words.

Tony Luck 7f30491ccd [IA64] Move include/asm-ia64 to arch/ia64/include/asm
After moving the the include files there were a few clean-ups:

1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h>

2) Some comments alerted maintainers to look at various header files to
make matching updates if certain code were to be changed. Updated these
comments to use the new include paths.

3) Some header files mentioned their own names in initial comments. Just
deleted these self references.
