5a0efea09f sparc64: Sharpen address space randomization calculations.
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.

b7afdb7e85 sparc32: add irq + smp declarations to headers
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.

7279b82cb1 SPARC/LEON: power down instruction different of different LEONs
The way a LEON is powered down is implemented differently depending
on CHIP type. The AMBA Plug&Play system ID tells revision of GRLIB

This is for example needed by the GR-LEON4-ITX board and the UT699.

Previously the power down support for LEON was limited to SMP, now

b62818e5ff sparc64: Fix NMI startup bug which also breaks perf.
Doing NMI startup as an early initcall doesn't work because we need
to have SMP started up by then.

So we'd only NMI startup one cpu, which causes perf PMU grab to
BUG because the nmi_active count isn't what it's supposed to be.

This also points out that we don't have proper CPU up/down notifiers
for the NMI code which will need to be fixed at some point.

711c71a092 sparc: fix size argument to find_next_zero_bit()
iommu_alloc_ctx() finds a zero bit in iommu->ctx_bitmap.  It starts
searching from iommu->ctx_lowest_free to the end of the bitmap.
But the size argument to find_next_zero_bit() in iommu_alloc_ctx()
is wrong.  It should be the bitmap size, not the maximum size to
search from the offset argument.

Fortunately iommu->ctx_lowest_free is almost unused and it will not
be more than 1. So the bug wasted only 1-bit at the end of
iommu->ctx_bitmap.

d0a21265df mm: unify module_alloc code for vmalloc
Four architectures (arm, mips, sparc, x86) use __vmalloc_area() for
module_init().  Much of the code is duplicated and can be generalized in a
globally accessible function, __vmalloc_node_range().

__vmalloc_node() now calls into __vmalloc_node_range() with a range of
[VMALLOC_START, VMALLOC_END) for functionally equivalent behavior.

Each architecture may then use __vmalloc_node_range() directly to remove
the duplication of code.

5edddaab1d sparc64: Fix bootup regression due to perf init ordering.
Commit 004417a6d4
("perf, arch: Cleanup perf-pmu init vs lockup-detector")
move the perf events init to be an early_initcall.

But this won't work properly unless the dependencies for
this code initialize beforehand.

Fix it by making cpu_type_probe and pcr_arch_init be
an early_initcall as well.

b2a39b0d8e sparc: use _start for the start entry (like 64 bit does)
We use "_start" in 64 bit - do the same in 32 bit.
It is always good to be consistent.

e405ae76af sparc: use trapbase in setup_arch
start and trapbase point to the same address.
But using start to assing to sparc_ttable looked confusing.

Replace this with the use of trapbase.

9663eb21fc SPARC/LEON: avoid AMBAPP name duplicates in openprom fs when REG is missing
When the REG property is not available the NODE-ID is used as an unique
identifier in order to avoid filesystem name duplicates in /proc/openprom
filesystem

e2305e37d4 SPARC/LEON: added support for IRQAMP IRQ Controller
Needed for LEON AMP systems where different CPUs are routed to

different IRQ controllers. This patch selects the IRQ Controller
which has been routed to the boot CPU, it is up to the boot loader
to configure the IRQ controller.
