Kjetil Oftedal 1c833bc3b6 sparc32: Fix multiple RTC detections on SUN4D
During the preparation for testing the recent changes made to the SUN4D
specific code in the kernel by Sam Ravnborg the following was discovered:

Since the removal of of_platform_bus_type (commit: eca3930163 )
multiboard SUN4Ds have not been able to boot. The kernel crashes due to a
zero-pointer error encountered when registering multiple M48T59 RTCs
(There is one on each board).

A patch for the was previously submitted, but the problem was not a
serious at that time, as it would only generate warnings. Now the kernel
will crash and stop executing before the serial console has been started.
(Crash output can be viewed by using the -p boot flag)

David S. Miller 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.

So we'd only NMI startup one cpu, which causes perf PMU grab to

Akinobu Mita 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.

David Rientjes 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.

David S. Miller 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.
