"We have one important patch from Dave Anglin and myself which fixes
PTE/TLB race conditions which caused random segmentation faults on our

* 'parisc-4.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: Fix some PTE/TLB race conditions and optimize __flush_tlb_range based on timing results
stifb: Implement hardware accelerated copyarea
The increased use of pdtlb/pitlb instructions seemed to increase the
frequency of random segmentation faults building packages. Further, we
had a number of cases where TLB inserts would repeatedly fail and all
forward progress would stop. The Haskell ghc package caused a lot of
trouble in this area. The final indication of a race in pte handling was
this syslog entry on sibaris (C8000):
swap_free: Unused swap offset entry 00000004
BUG: Bad page map in process mysqld pte:00000100 pmd:019bbec5

[<00000000402ba2a4>] SyS_madvise+0x404/0x8c0
Note that the pte value is 0 except for the accessed bit 0x100. This bit
shouldn't be set without the present bit.
It should be noted that the madvise system call is probably a trigger for many
of the random segmentation faults.
In looking at the kernel code, I found the following problems:
1) The pte_clear define didn't take TLB lock when clearing a pte.
2) We didn't test pte present bit inside lock in exception support.
3) The pte and tlb locks needed to merged in order to ensure consistency
between page table and TLB. This also has the effect of serializing TLB
broadcasts on SMP systems.
The attached change implements the above and a few other tweaks to try
to improve performance. Based on the timing code, TLB purges are very
slow (e.g., ~ 209 cycles per page on rp3440). Thus, I think it
beneficial to test the split_tlb variable to avoid duplicate purges.
Probably, all PA 2.0 machines have combined TLBs.
I dropped using __flush_tlb_range in flush_tlb_mm as I realized all
applications and most threads have a stack size that is too large to
make this useful. I added some comments to this effect.
Since implementing 1 through 3, I haven't had any random segmentation
faults on mx3210 (rp3440) in about one week of building code and running
as a Debian buildd.

We currently set x27 in compat_sys_sigreturn_wrapper and
compat_sys_rt_sigreturn_wrapper, similarly to what we do with r8/why on
32-bit ARM, in an attempt to prevent sigreturns from being restarted.
However, on arm64 we have always used pt_regs::syscallno for syscall
restarting (for both native and compat tasks), and x27 is never
inspected again before being overwritten in kernel_exit.
This patch removes the pointless register assignments.

We were using the native syscall and that results in subtle breakage.
This is the same issue as fixed in 077d0e6561
(MIPS: N32: Use compat getsockopt syscall) but that commit did fix it only
for N32.

The L2 cache in the I6400 core has 16 ways, so extend the way_string
array to take such caches into account.
[ralf@linux-mips.org: Other already supported CPUs are free to support
more than 8 ways of cache as well.]

Implement the mips_cdmm_phys_base() platform callback to provide a
default Common Device Memory Map (CDMM) physical base address for the
Pistachio SoC. This allows the CDMM in each VPE to be configured and
probed for devices, such as the Fast Debug Channel (FDC).
The physical address chosen is just below the default CPC address, which
appears to also be unallocated.
The FDC IRQ is also usable on Pistachio, and is routed through the GIC,
so implement the get_c0_fdc_int() platform callback using
gic_get_c0_fdc_int(), so the FDC driver doesn't have to fall back to
polling.

Wider testing reveals that the Fast Debug Channel (FDC) interrupt is
routed through the GIC just fine on Pistachio SoC, even though it
contains interAptiv cores. Clearly the FDC interrupt routing problems
previously observed on interAptiv and proAptiv cores are specific to the
Malta FPGA bitstreams.
Move the workaround for interAptiv and proAptiv out of
gic_get_c0_fdc_int() in the GIC irqchip driver into Malta's
get_c0_fdc_int() platform callback, to allow the Pistachio SoC to use
the FDC interrupt.

MT_SMP is not the only SMP option for MT cores. The MT_SMP option
allows more than one VPE per core to appear as a secondary CPU in the
system. Because of how CM works, it propagates the address-based
cache ops to the secondary cores but not the index-based ones.
Because of that, the code does not use IPIs to flush the L1 caches on
secondary cores because the CM would have done that already. However,
the CM functionality is independent of the type of SMP kernel so even in
non-MT kernels, IPIs are not necessary. As a result of which, we change
the conditional to depend on the CM presence. Moreover, since VPEs on
the same core share the same L1 caches, there is no need to send an
IPI on all of them so we calculate a suitable cpumask with only one
VPE per core.

except for a GPMC fix to not use names for probing devices. Also a
one liner clean-up to remove unecessary return from a void function.
The summary for the changes being:
- Fix probe for GPMC devices by reoving limitations based on device
name
- Remove unnecessary return from a void function
- Revert beaglebone RTC sleep fix, we now have a better fix merged
- Add am4372 EMIF node to fix a warning
- Add am57xx-beagle-x15 power supply to fix USB2 if USB1 is disabled
- Disable rfbi for am4372 as it does not have a driver
