sparc64: Fix definition of VMEMMAP_SIZE.

2009-11-24T00:38:56+00:00

This was the cause of various boot failures on V480, V880, etc.
systems.

Kernel image memory was being overwritten because the vmemmap[]
array was being sized to small.  So if you had physical memory
addresses past a certain point, the early bootup would spam
all over variables in the kernel data section.

The vmemmap mappings map page structs, not page struct pointers.
And that was the key thinko in the macro definition.

This was fixable thanks to the help, reports, and tireless patience
of Hermann Lauer.

sparc64: replace parentheses in pmul()

2009-11-08T08:26:56+00:00

`>>' has a higher precedence than `?' so src2 evaluated to
either 16 or 0 dependent on the bits set in rs2.

sparc64: Set IRQF_DISABLED on LDC channel IRQs.

2009-10-13T07:49:09+00:00

With lots of virtual devices it's easy to generate a lot of
events and chew up the kernel IRQ stack.

sparc64: Fix D-cache flushing on swapin from SW devices.

2009-10-12T10:20:57+00:00

Thanks to tip form ARM folks and Russell King.

If flush_dcache_page() occurs on a swapin it will have a mapping
and we'll try to defer the flush by setting the dirty bit.

But when it hits update_dcache_page() we won't flush because the
page won't have a mapping any more.  So remove the mapping
requirement in flush_dcache().
