Because driver is accessing a common MII structure in
mii_pollstat(), updating user supplied structure should be done
before dropping a driver lock.

Reading /dev/mem in 64 bit kernel crashes. This is because the page
used to call uiomove_fromphys() from memrw() does not have md.pv_list
initialized correctly.
The fix is to call pmap_page_init() on the page to initialize it.

Wrong in that it must be guarded (it's configurable)
and bogus in that there's absolutely no rationale for

octeon_ap_boot is not a bitmask. It holds the CPU Id of the
AP currently being started. As such there's no need to make
it a 64-bit integral and we're not limited to 64 CPUs.

patch modifies makesyscalls.sh to prefix all of the non-compatibility
calls (e.g. not linux_, freebsd32_) with sys_ and updates the kernel
entry points and all places in the code that use them. It also
fixes an additional name space collision between the kernel function
psignal and the libc function of the same name by renaming the kernel
psignal kern_psignal(). By introducing this change now we will ease future
MFCs that change syscalls.

are non-blocking. The vm_page_aflag_set(9) and vm_page_aflag_clear(9)

Introduce vm_page_reference(9) function to provide a stable KPI and

* Update the hardware access register definitions and functions to bring
them in line with other Netlogic software.
* Update the platform bus to use PCI even for on-chip devices. Add a dummy
PCI driver to ignore on-chip devices which do not need driver.
* Provide memory and IRQ resource allocation code for on-chip devices
which cannot get it from PCI config.
* add support for on-chip PCI and USB interfaces.
* update conf files, enable pci and retain old MAXCPU until we can support
>32 cpus.

From now on, default values for FreeBSD will be 64 maxiumum supported
CPUs on amd64 and ia64 and 128 for XLP. All the other architectures
seem already capped appropriately (with the exception of sparc64 which
needs further support on jalapeno flavour).
Bump __FreeBSD_version in order to reflect KBI/KPI brekage introduced
during the infrastructure cleanup for supporting MAXCPU > 32. This
covers cpumask_t retiral too.
The switch is considered completed at the present time, so for whatever
bug you may experience that is reconducible to that area, please report
immediately.

- For amd64/i386 remove the storage of intr* stuff from assembly files.
This area can be widely improved by applying the same to other
architectures and likely finding an unified approach among them and
move the whole code to be MI. More work in this area is expected to
happen fairly soon.

This patch adds support for the Netlogic XLP mips64 processors in
the common MIPS code. The changes are :
- Add CPU_NLM processor type
- Add cases for CPU_NLM, mostly were CPU_RMI is used.
- Update cache flush changes for CPU_NLM
- Add kernel build configuration files for xLP.

mask of CPUs, pc_other_cpus and pc_cpumask become highly inefficient.
Remove them and replace their usage with custom pc_cpuid magic (as,
atm, pc_cpumask can be easilly represented by (1 << pc_cpuid) and
pc_other_cpus by (all_cpus & ~(1 << pc_cpuid))).
This change is not targeted for MFC because of struct pcpu members
removal and dependency by cpumask_t retirement.

option to vm_object_page_remove() asserts that the specified range of pages
is not mapped, or more precisely that none of these pages have any managed
mappings. Thus, vm_object_page_remove() need not call pmap_remove_all() on
the pages.
This change not only saves time by eliminating pointless calls to
pmap_remove_all(), but it also eliminates an inconsistency in the use of
pmap_remove_all() versus related functions, like pmap_remove_write(). It
eliminates harmless but pointless calls to pmap_remove_all() that were being
performed on PG_UNMANAGED pages.
Update all of the existing assertions on pmap_remove_all() to reflect this
change.

signalled when the attribute address for the CF is 0 in the octeon
sysinfo structure. In this mode, the DATA port is 16-bits, but the
other ports are 8-bits, but on a 16-bit bus (so you have to access it
a short at a time, but only believe the lower byte). See the code for
more details on this slightly odd arrangement. I'm still not 100%
happy with the abstractions here on many levels (starting with the
globals for these settings, on down to no bus_space use, etc), but the
driver had these problems before the change.
Also, clean up the code a bit to make this support easier, and the
code a bit easier to read. I tried to follow existing style, but may
have missed a few spots. Add some comments.
Fix probe/attach routine to return a proper error for the simulator.
With this change, my EBH5200 eval board now recognizes the CF well
enough to boot to the login prompt. Before it would say it never
became ready. My CN3010-EVB-HS5 still boots properly. My older
CN3860-based board won't load the 64-bit kernel, either before or
after the change, and I didn't chase that down.

be brought up in the order they are enumerated in the device tree (in
particular, that thread 0 on each core be brought up first). The SLIST
through which we loop to start the CPUs has all of its entries added with
SLIST_INSERT_HEAD(), which means it is in reverse order of enumeration
and so AP startup would always fail in such situations (causing a machine
check or RTAS failure). Fix this by changing the SLIST into an STAILQ,
and inserting new CPUs at the end.

The native implementation is bogus in that regard and offers the same

Also commit the comment changes to kmem_init_zero_region() that I
