[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.

12 * PIC AS DEVICE ZERO
13 * ------------------
14 *
15 * PIC handles PCI/X busses. PCI/X requires that the 'bridge' (i.e. PIC)
16 * be designated as 'device 0'. That is a departure from earlier SGI
17 * PCI bridges. Because of that we use config space 1 to access the
18 * config space of the first actual PCI device on the bus.
19 * Here's what the PIC manual says:
20 *
21 * The current PCI-X bus specification now defines that the parent
22 * hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
23 * reduced the total number of devices from 8 to 4 and removed the
24 * device registers and windows, now only supporting devices 0,1,2, and
25 * 3. PIC did leave all 8 configuration space windows. The reason was
26 * there was nothing to gain by removing them. Here in lies the problem.
27 * The device numbering we do using 0 through 3 is unrelated to the device
28 * numbering which PCI-X requires in configuration space. In the past we
29 * correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
30 * PCI-X requires we start a 1, not 0 and currently the PX brick
31 * does associate our:
32 *
33 * device 0 with configuration space window 1,
34 * device 1 with configuration space window 2,
35 * device 2 with configuration space window 3,
36 * device 3 with configuration space window 4.
37 *
38 * The net effect is that all config space access are off-by-one with
39 * relation to other per-slot accesses on the PIC.
40 * Here is a table that shows some of that:
41 *
42 * Internal Slot#
43 * |
44 * | 0 1 2 3
45 * ----------|---------------------------------------
46 * config | 0x21000 0x22000 0x23000 0x24000
47 * |
48 * even rrb | 0[0] n/a 1[0] n/a [] == implied even/odd
49 * |
50 * odd rrb | n/a 0[1] n/a 1[1]
51 * |
52 * int dev | 00 01 10 11
53 * |
54 * ext slot# | 1 2 3 4
