Move memory_present() in arch/mips/kernel/setup.c. When using sparsemem
extreme, this function does an allocate for bootmem. This would always
fail since init_bootmem hasn't been called yet.
Move memory_present after free_bootmem. This only marks actual memory
ranges as present instead of the entire address space.

After removal of fixup_cpu_present_map() function Alpha ended up with an empty
cpu_present_map, so secondary CPUs on SMP systems are not being started.
Worse, on some platforms we route interrupts to secondary CPUs using
cpu_possible_map which is still populated properly. As a result, these
interrupts go nowhere so the machines like DP264 aren't able to boot even with
a primary CPU.
Fixed basically by s/cpu_present_mask/cpu_present_map/.
Thanks to Ernst Herzberg for reporting the bug and testing the fix.

|

Patch from Lennert Buytenhek
On the ixp23xx, the microengine thread interrupt sources are numbered
56..119, but their mask/status bits are located in bit positions 64..127
in the various registers in the interrupt controller (bit positions
56..63 are unused.)
We don't deal with this, so currently, when asked to enable IRQ 64, we
will enable IRQ 56 instead.
The only interrupts >= 64 are the thread interrupt sources, and there
are no in-tree users of those yet, so this is fortunately not a big
problem, but this needs fixing anyway.

A proper fix would involve introducing the notion of shared caches but
at this stage of 2.6.17 that's going to be too intrusive and not needed
for current hardware; aside I think some discussion will be needed.
So for now on the affected SMP configurations which happen to suffer from
cache aliases we make use of the fact that a single cache will be shared
by all processors. This solves the deadlock issue and will improve
performance by getting rid of the smp_call_function overhead.

Prevent calling of some platform functions on the clock chips of the eMac

that doesn't seem to be important as the machine appear to work fine

This reverts commit 5491d0f3e206beb95eeb506510d62a1dab462df1.
As per Andi:
"After some discussion with people who have the affected system it
seems best to revert for 2.6.17. It broke a common BIOS workaround
and PCI-X still doesn't work. Alternative is for people to change
the BIOS which seems to be better right now."

Actually, we just stumbled on a different bug found in find_e820_area() in
e820.c. The following code does not handle the edge condition correctly:
while (bad_addr(&addr, size) && addr+size < ei->addr + ei->size)
;
last = addr + size;
if ( last > ei->addr + ei->size )
continue;
The second statement in the while loop needs to be a <= b so that it is the
logical negavite of the if (a > b) outside it. It needs to read:
while (bad_addr(&addr, size) && addr+size <= ei->addr + ei->size)
;
In the case that failed bad_addr was returning an address that is exactly size
bellow the end of the e820 range.

also include the memory from those cells. This can create a scenario where
node 0 has cpus, but no associated memory. The system will boot fine in a
configuration where node 0 has memory, but nodes 2 and 3 do not.
