e6597c747f Fix the EBus driver to work with the new PCI code. Unlike other PCI
bridges, the EBus bridge has resource ranges it claims exclusively to
map its children into in its BARs. Hence, we need to allocate these
completely and manage them for the children, instead of just passing
allocations through to the PCI layer as we did before.

While being there, split ebus_probe(), which did also contain code
normally belonging into the attach method, into ebus_probe() and
ebus_attach(), and perform some minor cleanups.

- Fix some comments; remove numerous superfluous or outdated ones.
- Correctly pass on the requesting device when handing requests up
  to the parent bus.
- Use the complete device name, including unit number, to build the

- Inline a function that was only used once, and was trivial.

6e7272f69d - Use an ihandle_t to store the stdout instance handle instead of a
phandle_t. Since both are typedefed to unsigned int, this is more
  or less cosmetic.
- Fix the code that determines whether a creator instance was used
  for firmware output (and should not be blanked on initialization).
  Since r1.2 of dev/fb/creator.c, this consisted comparing a handle of
  an instance of a package with a handle of the package itself.
  Use the test from r1.1, which utilizes OF_instance_to_package().

1c5043680e Add an implementation of uiomove_fromphys() to sparc64. This
implementation could be characterized as a hybrid of the amd64 and i386
implementations.  Specifically, the direct virtual-to-physical mapping is
used if possible and sf_buf_alloc() is used if the direct map cannot.

a36bdc0606 Introduce the cpumask_t type. The purpose of the type is to create a
level of abstraction for any and all CPU mask and CPU bitmap variables
so that platforms have the ability to break free from the hard limit
of 32 CPUs, simply because we don't have more bits in an u_int. Note
that the type is not supposed to solve massive parallelism, where
the number of CPUs can be larger than the width of the widest integral
type. As such, cpumask_t is not supposed to be a compound type. If
such would be necessary in the future, we can deal with the issues
then and there. For now, it can be assumed that the type is integral
and unsigned.

With this commit, all MD definitions start off as u_int. This allows
us to phase-in cpumask_t at our leasure without breaking anything.
Once cpumask_t is used consistently, platforms can switch to wider
(or smaller) types if such would be beneficial (or not; whatever :-)

90ecfebd82 Refactor the existing machine-dependent sf_buf_free() into a machine-
dependent function by the same name and a machine-independent function,
sf_buf_mext().  Aside from the virtue of making more of the code machine-
independent, this change also makes the interface more logical.  Before,
sf_buf_free() did more than simply undo an sf_buf_alloc(); it also
unwired and if necessary freed the page.  That is now the purpose of
sf_buf_mext().  Thus, sf_buf_alloc() and sf_buf_free() can now be used
as a general-purpose emphemeral map cache.

fcffa790e9 Retire pmap_pinit2(). Alpha was the last platform that used it. However,
ever since alpha/alpha/pmap.c revision 1.81 introduced the list allpmaps,
there has been no reason for having this function on Alpha.  Briefly,
when pmap_growkernel() relied upon the list of all processes to find and
update the various pmaps to reflect a growth in the kernel's valid
address space, pmap_init2() served to avoid a race between pmap
initialization and pmap_growkernel().  Specifically, pmap_pinit2() was
responsible for initializing the kernel portions of the pmap and
pmap_pinit2() was called after the process structure contained a pointer
to the new pmap for use by pmap_growkernel().  Thus, an update to the
kernel's address space might be applied to the new pmap unnecessarily,
but an update would never be lost.

TDP_ALTSTACK.
For single thread or Linux clone() based threaded program, there is no

798a45964d - Split cpu_mp_probe() into two parts. cpu_mp_setmaxid() is still called
very early (SI_SUB_TUNABLES - 1) and is responsible for setting mp_maxid.
  cpu_mp_probe() is now called at SI_SUB_CPU and determines if SMP is
  actually present and sets mp_ncpus and all_cpus.  Splitting these up
  allows an architecture to probe CPUs later than SI_SUB_TUNABLES by just
  setting mp_maxid to MAXCPU in cpu_mp_setmaxid().  This could allow the
  CPU probing code to live in a module, for example, since modules
  sysinit's in modules cannot be invoked prior to SI_SUB_KLD.  This is
  needed to re-enable the ACPI module on i386.
- For the alpha SMP probing code, use LOCATE_PCS() instead of duplicating
  its contents in a few places.  Also, add a smp_cpu_enabled() function
  to avoid duplicating some code.  There is room for further code
  reduction later since much of this code is also present in cpu_mp_start().
- All archs besides i386 still set mp_maxid to the same values they set it
  to before this change.  i386 now sets mp_maxid to MAXCPU.

0019917542 Fix a bug in the data access error recorvery. Before re-enabling the data
cache after a data access error we must discard all cache lines.  When
disabled existing cache lines are not invalidated by stores to memory, so
we risk reading stale data that was cached before the data access error if
we don't flush them.  This is especially fatal when the memory involved
is the active part of the kernel or user stack.  For good measure we also
flush the instruction cache.

This fixes random crashes when the X server probes the PCI bus through
/dev/pci.
