* sparc32,sun4m: percpu and global register definitions moved to irq.hSam Ravnborg2011-03-162-21/+30
| | | | | | | | | | | | entry.S access percpu + global data defined in sun4m_irq.c - so move the types to irq.h. This makes sparse happy and allow us to utilize asm-offsets later. Also updated a few comments in the sun4m_irq.c file. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: introduce build_device_irqSam Ravnborg2011-03-164-54/+68
| | | | | | | | | | | build_device_irq() is used to encapsulate the plaform specific details when we build an irq. For now the default is a simple 1:1 but sun4d differs. This patch refactors functionality - but does not change the existing functionality. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* sparc64: Sharpen address space randomization calculations.David S. Miller2011-03-161-8/+13
| | | | | | | | | | | | | | | | | | | | | | A recent patch to the x86 randomization code caused me to take a quick look at what we do on sparc64, and in doing so I noticed that we sometimes calculate a non-page-aligned randomization value and stick it into mmap_base. I also noticed that since I copied the logic over from PowerPC, the powerpc code has tweaked the randomization ranges in ways that would benefit us as well. For one thing, we should allow up to at least 8MB of randomization otherwise huge-page regions when HPAGE_SIZE is 4MB never randomize at all. And on the 64-bit side we were using up to 4GB. Tone it down to 1GB as 4GB can result in a lot of address space wastage. Finally, make sure all computations are unsigned. Signed-off-by: David S. Miller <davem@davemloft.net>

* sparc32: add irq + smp declarations to headersSam Ravnborg2011-03-165-13/+68
| | | | | | | | | | | | | | | | | | | In preparation for cleaning up a number of files add declarations for irq and smp related data/functions to the relevant headers. This showed that the extern declaration of cputypval differed in the two files where it was used. As cputypval is defined like this: cputypval: .asciz "sun4c" the correct representation is a char array. Fix users to use the new declaration.

| | | | | | | | | | | | | | | The way a LEON is powered down is implemented differently depending on CHIP type. The AMBA Plug&Play system ID tells revision of GRLIB and CHIP.
