alpha: cleanups and build fixes

Browse Source 
I had investigated dropping support for alpha EV5 and earlier a while
 ago after noticing that this is the only supported CPU family
 in the kernel without native byte access and that Debian has already
 dropped support for this generation last year [1] in order to
 improve performance for the newer machines.
 
 This topic came up again when Paul E. McKenney noticed that
 parts of the RCU code already rely on byte access and do not
 work on alpha EV5 reliably, so we decided on using my series to
 avoid the problem entirely.
 
 Al Viro did another series for alpha to address all the known build
 issues. I rebased his patches without any further changes and included
 it as a baseline for my work here to avoid conflicts and allow
 backporting the fixes to stable kernels for the now removed hardware
 support as well.

[ I dearly loved alpha back in the days, but the lack of byte and word
  operations was a horrible mistake and made everything worse -
  including very much the crazy IO contortions that resulted from it.

  It certainly wasn't the only mistake in the architecture, but it's the
  first-order issue.

  So while it's a bit sad to see the support for my first alpha go away,
  if you want to run museum hardware, maybe you should use museum
  kernels..    - Linus ]

UDB). This design was produced by Digital's Technical OEM (TOEM)
group. It uses the 21066 processor running at 166MHz or 233MHz. It
is a baby-AT size, and runs from a standard PC power supply. It has
5 ISA slots and 3 PCI slots (one pair are a shared slot). There are
2 versions, with either PS/2 or large DIN connectors for the

An AVANTI *might* be an XL, and an XL has only 27 bits of ISA address
that get passed through the PCI<->ISA bridge chip. So we've gotta use
both windows to max out the physical memory we can DMA to. Sigh...
If we try a window at 0 for 1GB as a work-around, we run into conflicts
with ISA/PCI bus memory which can't be relocated, like VGA aperture and
BIOS ROMs. So we must put the windows high enough to avoid these areas.
We put window 1 at BUS 64Mb for 64Mb, mapping physical 0 to 64Mb-1,
and window 2 at BUS 1Gb for 1Gb, mapping physical 0 to 1Gb-1.
Yes, this does map 0 to 64Mb-1 twice, but only window 1 will actually
be used for that range (via virt_to_bus()).
Note that we actually fudge the window 1 maximum as 48Mb instead of 64Mb,
to keep virt_to_bus() from returning an address in the first window, for
a data area that goes beyond the 64Mb first DMA window. Sigh...
The fudge factor MUST match with <asm/dma.h> MAX_DMA_ADDRESS, but
we can't just use that here, because of header file looping... :-(
Window 1 will be used for all DMA from the ISA bus; yes, that does
limit what memory an ISA floppy or sound card or Ethernet can touch, but
it's also a known limitation on other platforms as well. We use the
same technique that is used on INTEL platforms with similar limitation:
set MAX_DMA_ADDRESS and clear some pages' DMAable flags during mem_init().
We trust that any ISA bus device drivers will *always* ask for DMAable
memory explicitly via kmalloc()/get_free_pages() flags arguments.
Note that most PCI bus devices' drivers do *not* explicitly ask for
DMAable memory; they count on being able to DMA to any memory they
get from kmalloc()/get_free_pages(). They will also use window 1 for
any physical memory accesses below 64Mb; the rest will be handled by
window 2, maxing out at 1Gb of memory. I trust this is enough... :-)
We hope that the area before the first window is large enough so that
there will be no overlap at the top end (64Mb). We *must* locate the
PCI cards' memory just below window 1, so that there's still the
possibility of being able to access it via SPARSE space. This is
important for cards such as the Matrox Millennium, whose Xserver
wants to access memory-mapped registers in byte and short lengths.
Note that the XL is treated differently from the AVANTI, even though
for most other things they are identical. It didn't seem reasonable to
make the AVANTI support pay for the limitations of the XL. It is true,
however, that an XL kernel will run on an AVANTI without problems.
%%% All of this should be obviated by the ability to route
everything through the iommu.

/*
* NOTE: The LCA uses a Host Address Extension (HAE) register to access
* PCI addresses that are beyond the first 27 bits of address
* space. Updating the HAE requires an external cycle (and
* a memory barrier), which tends to be slow. Instead of updating
* it on each sparse memory access, we keep the current HAE value
* cached in variable cache_hae. Only if the cached HAE differs
* from the desired HAE value do we actually updated HAE register.
* The HAE register is preserved by the interrupt handler entry/exit
* code, so this scheme works even in the presence of interrupts.
*
* Dense memory space doesn't require the HAE, but is restricted to
* aligned 32 and 64 bit accesses. Special Cycle and Interrupt
* Acknowledge cycles may also require the use of the HAE. The LCA
* limits I/O address space to the bottom 24 bits of address space,
* but this easily covers the 16 bit ISA I/O address space.
*/
/*
* NOTE 2! The memory operations do not set any memory barriers, as
* it's not needed for cases like a frame buffer that is essentially
* memory-like. You need to do them by hand if the operations depend
* on ordering.
*
* Similarly, the port I/O operations do a "mb" only after a write
* operation: if an mb is needed before (as in the case of doing
* memory mapped I/O first, and then a port I/O operation to the same
* device), it needs to be done by hand.
*
* After the above has bitten me 100 times, I'll give up and just do
* the mb all the time, but right now I'm hoping this will work out.
* Avoiding mb's may potentially be a noticeable speed improvement,
* but I can't honestly say I've tested it.
*
* Handling interrupts that need to do mb's to synchronize to
* non-interrupts is another fun race area. Don't do it (because if
* you do, I'll have to do *everything* with interrupts disabled,
* ugh).
