Add 8548 CPU definition and attributes

  8548 CPU is GCC's name for the e500v2, so accept this in clang.  The
  e500v2 doesn't support lwsync, so define __NO_LWSYNC__ for this as
  well, as GCC does.

  Summary:

  As currently written, -target powerpcspe will enable SPE regardless
  of disabling the feature later on in the command line.  Instead,
  change this to just set a default CPU to 'e500' instead of a generic

d1df7fdd04 mps(4): add missing cam(4) dependency
On a MINIMAL kernel, mps.ko wouldn't load because it uses the xpt_hold_boot
symbol from CAM, but didn't have a dependency on cam(4).

(CEM: Some context: when linking loaded modules, the kernel dynamic linker
only looks for definitions in explictly marked dependency modules.  Also,
the identical mpr(4) driver uses the same CAM function, but already had the
correct MODULE_DEPEND(), so no similar change is needed there.)

95a8fce118 [PowerPC64] fix crash when using machdep.moea64_bpvo_pool_size tunable
Summary:
This fixes kernel crashing when tunable "machdep.moea64_bpvo_pool_size" is
set to a value higher then 327680 (default value).  Function
moea64_mid_bootstrap() relies on moea64_bpvo_pool_size, but at time of the
use the variable wan't yet updated with the new value provided by user.

Problem was detected after trying to use a VM with 64GB of RAM, and default
moea64_bpvo_pool_size is insufficient (kernel boot used more than 470000) .
I think default value must be discussed to address this use case, or find a
way to calculate pool size automatically based on amount of memory detected.

Test Plan: Tested on QEMU VM with 64GB of RAM using "set
machdep.moea64_bpvo_pool_size=655360" on loader prompt

d07cc22b30 arm: allwinner: Fix padconf for interrupts information
Add a eint_bank member to the allwinner_pins structure.
On Allwinner SoCs not all pins can do interrupt.
Older SoC (A10/A13 and A20) there is a maximum number of interrupts
set to 32 and all the configuration is done in the same registers.
While on "newer" SoCs (>=A31) interrupts registers are splitted per
pin bank (i.e. all interrupts available in bank B will be configured
with a sets of registers and the one in bank G in another set).
While here set the names to all interrupts function to
pX_eintY where X is the bank name and Y the interrupt number.

To whom ever in the future look at the H5 manual and notice that the bank F
have interrupts support : This isn't true, trust me.

98087a066f Make collapse synchronization more explicit and allow it to complete during
paging.

Shadow objects are marked with a COLLAPSING flag while they are collapsing with
their backing object.  This gives us an explicit test rather than overloading
paging-in-progress.  While split is on-going we mark an object with SPLIT.
These two operations will modify the swap tree so they must be serialized
and swap_pager_getpages() can now directly detect these conditions and page
more conservatively.

Callers to vm_object_collapse() now will reliably wait for a collapse to finish
so that the backing chain is as short as possible before other decisions are
made that may inflate the object chain.  For example, split, coalesce, etc.
It is now safe to run fault concurrently with collapse.  It is safe to increase
or decrease paging in progress with no lock so long as there is another valid
ref on increase.

This change makes collapse more reliable as a secondary benefit.  The primary
benefit is making it safe to drop the object lock much earlier in fault or
never acquire it at all.

This was tested with a new shadow chain test script that uncovered long
standing bugs and will be integrated with stress2.

a8614f0eec [PowerPC] Fix 32-bit ubldr calling convention
Due to the way u-boot for 32-bit powerpc is compiled, the interrupt code
assumes that the GOT pointer (r30) on u-boot is always intact.

When making syscalls to u-boot, ensure that we have restored r30 like we
found it before we enable interrupts to prevent u-boot from crashing if a
timer interrupt was pending.

This fixes ubldr on e500 qemu (assuming you have recompiled qemu's u-boot
with API support!)
