Fix page fault handling code to fixup r16-r18 registers.
Before the patch code had off-by-two registers bug.
This bug caused overwriting of ps,pc,gp registers instead
of fixing intended r16,r17,r18 (see `struct pt_regs`).
More details:
Initially Dmitry noticed a kernel bug as a failure
on strace test suite. Test passes unmapped userspace
pointer to io_submit:
```c
#include <err.h>
#include <unistd.h>
#include <sys/mman.h>
#include <asm/unistd.h>
int main(void)
{
unsigned long ctx = 0;
if (syscall(__NR_io_setup, 1, &ctx))
err(1, "io_setup");
const size_t page_size = sysconf(_SC_PAGESIZE);
const size_t size = page_size * 2;
void *ptr = mmap(NULL, size, PROT_READ | PROT_WRITE,
MAP_PRIVATE | MAP_ANONYMOUS, -1, 0);
if (MAP_FAILED == ptr)
err(1, "mmap(%zu)", size);
if (munmap(ptr, size))
err(1, "munmap");
syscall(__NR_io_submit, ctx, 1, ptr + page_size);
syscall(__NR_io_destroy, ctx);
return 0;
}
```
Running this test causes kernel to crash when handling page fault:
```

Disabling lock debugging due to kernel taint
Trace:
[<fffffc0000311404>] entSys+0xa4/0xc0
```
Here `gp` has invalid value. `gp is s overwritten by a fixup for the
following page fault handler in `io_submit` syscall handler:
```
__se_sys_io_submit
...
ldq a1,0(t1)
bne t0,4280 <__se_sys_io_submit+0x180>
```
After a page fault `t0` should contain -EFALUT and `a1` is 0.
Instead `gp` was overwritten in place of `a1`.
This happens due to a off-by-two bug in `dpf_reg()` for `r16-r18`
(aka `a0-a2`).
I think the bug went unnoticed for a long time as `gp` is one
of scratch registers. Any kernel function call would re-calculate `gp`.
Dmitry tracked down the bug origin back to 2.1.32 kernel version
where trap_a{0,1,2} fields were inserted into struct pt_regs.
And even before that `dpf_reg()` contained off-by-one error.

Eiger machine vector definition has nr_irqs 128, and working 2.6.26
boot shows SCSI getting IRQ-s 64 and 65. Current kernel boot fails
because Symbios SCSI fails to request IRQ-s and does not find the disks.
It has been broken at least since 3.18 - the earliest I could test with
my gcc-5.
The headers have moved around and possibly another order of defines has
worked in the past - but since 128 seems to be correct and used, fix
arch/alpha/include/asm/irq.h to have NR_IRQS=128 for Eiger.
This fixes 4.19-rc7 boot on my Force Flexor A264 (Eiger subarch).

set_pmd_at() calls native_set_pmd() unconditionally on x86. This was
fine as long as only huge page entries were written via set_pmd_at(),
as Xen pv guests don't support those.
Commit 2c91bd4a4e ("mm: speed up mremap by 20x on large regions")
introduced a usage of set_pmd_at() possible on pv guests, leading to
failures like:

This is a bit larger than normal, as we had not managed to send out
a pull request before traveling for a week without my signing key.
There are multiple code fixes for older bugs, all of which should
get backported into stable kernels:
- tango: one fix for multiplatform configurations broken on other
platforms when tango is enabled
- arm_scmi: device unregistration fix
- iop32x: fix kernel oops from extraneous __init annotation
- pxa: remove a double kfree
- fsl qbman: close an interrupt clearing race
The rest is the usual collection of smaller fixes for device tree
files, on the renesas, allwinner, meson, omap, davinci, qualcomm
and imx platforms. Some of these are for compile-time warnings,
most are for board specific functionality that fails to work
because of incorrect settings.

Just two fixes, both going to stable.
Our support for split pmd page table lock had a bug which could lead to a crash
on mremap() when using the Radix MMU (Power9 only).
A fix for the PAPR SCM driver (nvdimm) we added last release, which had a bug
where we might mis-handle a hypervisor response leading to us failing to attach
the memory region.
