Disintegrate asm/system.h for Alpha.

T2 are the only alpha SMP systems that do HAE switching at runtime, which
is fundamentally racy on SMP. This patch limits MMIO space on T2 to HAE0
only, like we did on MCPCIA (rawhide) long ago. This leaves us with only
112 Mb of PCI MMIO (128 Mb HAE aperture minus 16 Mb reserved for EISA),
but since linux PCI allocations are reasonably tight, it should be enough
for sane hardware configurations.
Also, fix a typo in MCPCIA_FROB_MMIO macro which shouldn't call set_hae()
if MCPCIA_ONE_HAE_WINDOW is defined. It's more for correctness, as
set_hae() is a no-op anyway in that case.

spin_* functions are mostly static inline now. That causes the alpha
compile to fail:
CC arch/alpha/kernel/sys_sable.o
cc1: warnings being treated as errors
In file included from arch/alpha/kernel/sys_sable.c:25:
arch/alpha/include/asm/core_t2.h: In function 't2_readb':
arch/alpha/include/asm/core_t2.h:451: error: 'spinlock_check' is static but \
used in inline function 't2_readb' which is not static
arch/alpha/include/asm/core_t2.h:456: error: 'spin_unlock_irqrestore' is \
static but used in inline function 't2_readb' which is not static
That's caused by the "extern inline" magic which is used for the
subarch specific read/write[bwl] functions. I tried to distangle the
uncountable macro onion layers, but failed miserably.
Last resort solution: switch the t2_hae_lock to raw_spinlock_t so the
lock functions are pure macros and function calls again.

Vast majority of these build failures are gcc-4.3 warnings
about static functions and objects being referenced from
non-static (read: "extern inline") functions, in conjunction
with our -Werror.
We cannot just convert "extern inline" to "static inline",
as people keep suggesting all the time, because "extern inline"
logic is crucial for generic kernel build.
So
- just make sure that all callees of critical "extern inline"
functions are also "extern inline";
- use "static inline", wherever it's possible.
traps.c: work around gcc-4.3 being too smart about array
bounds-checking.
TODO: add "gnu_inline" attribute to all our "extern inline"
functions to ensure desired behaviour with future compilers.

__FUNCTION__ is gcc-specific, use __func__
The change in pci-iommu,c should be safe as arena has not been assigned
when we get to this point.
Some were within #if 0 blocks, have changed them and left the blocks
as they appear to be debugging infrastructure.
A #define FN __FUNCTION__ was removed and occurances of FN were replaced
with __func__ as well.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
