I tracked this one to the `netbsd32_adjust_limits()' function (called
when creating a new process under compat_netbsd32), where data and
stack limits are set without checking for shared `p_limit' structure
(p_limit->p_refcnt > 1). This explain the side effect where processes
have their limits changed when a compat_netbsd32 (or compat_linux32)
program is run.
The fix is to use `dosetrlimit()' to ensure the needed copy-on-write
behaviour for shared structure.

which have virtual address indexed cache and whose pmaps don't always
allow normal shared mappings even for read only pages.
In future, these pmaps should be rewritten to handle such read only
shared mappings properly like ARM pmap, but currently we just disable
sosend_loan() to avoid unnecessary uncached mappings and cache flushes
on MIPS3 CPUs, or map/unmap thrashing on SH4.

from cpu_configure(9) to cpu_initclocks(9) on mips ports which use
mips3_clockintr.c:mips3_clockintr() (i.e. CPU INT5 clock) to avoid
hardclock(9) before softclock interrupt is initialized in initclocks().
This should be harmless because initclocks() is a part of configure()
in these days and there is no MI function which expects hardware
interrupts between cpu_configure(9) and cpu_initclocks(9).

event should be raised every 10ms if we're runnable. Unfortunately,
there seems to be an intermittent bug in the hypervisor such that,
for about 1<<32 ns (~4.3s) after it manifests, every running domain
continues to run but not get its timer events and new timestamps (nor
is it preempted in favor of other domains on that CPU). This can cause
strange behavior from our timekeeping; for example, hardclock() is never
called during this interval.
So here's a workaround: if timestamp is allegedly up to date but is more
than 40ms old (this is semi-arbitrary), the domain sets its timer to a
time in the past, which causes it to become immediately pending, and also
results in the publication of a new timestamp.
I'm leaving those platforms with few users and those whose machines are
not very powerful untouched per uwe@'s suggestion. The port masters or
the real users of those ports are better suited to make the decision of
enabling it.

To software, the unit is very similar to the IQ80321 and IQ31244 eval
boards from Intel. As such, we share almost all of their code.
Onboard hardware:
- IOP321 XScale CPU. Core clock is 600MHz.
- 256MB SDRAM (not sure if that's true for all)
- Four-port Intel i31244 SATA controller. One port is connected to the
internal disk. The remaining three are available on the back-panel.
- Dual GigE ports on the back panel, using an Intel i82546EB controller.
- Two Symbios Logic 53c1010 SCSI controllers, one in host mode the other
in target mode. Both SCSI busses are available on the back panel.
Note that NetBSD does not support SCSI target mode.
- 8MB of NOR Flash, containing a fairly vanilla Redboot together with

devices hooked up to the HPI pin.
HPIs cannot be masked at the interrupt controller; they can only be masked
by disabling IRQs in the XScale core. To deal with this, we tweak the
interrupt frame so that IRQs are disabled when the interrupt dispatcher
returns due to a masked HPI interrupt. IRQs will be re-enabled by a
subsequent splx(9).
Fortunately the only instance where HPI is used is for the console UART
on a couple of boards, so this hack does not adversely affect performance.

those not tied up in active mbufs, rather than half of the total number.
(Or, to more literally translate the C, when there are at least as
many buffers waiting to be reused as outstanding rx requests.)
This prevents us from dropping off the network for a while when more
than 128 of the 256 buffers are in use by mbufs, which might not be
freed for an arbitrarily long time; the remaining buffers would stack up
on the free list but not be reclaimed until enough mbufs were eventually
freed, leaving the interface unable to receive packets until then.
Checking all zsc units in zshard() is efficient only on ports
which share one interrupt among all zsc units, like sparc or sun3.
On such ports, zshard() is established as a handler only once.
XXX1: more other MD zs drivers should be fixed similarly.
XXX2: zsc on macppc has independent interrupts for channel A and B,
but MI z8530sc can't handle such configuration.
INSTALL.MP, INSTALL_LAPTOP, and DISKLESS kernels so that they are
smaller and faster by removing support for actual i386 CPUs (which
lack write protection in supervisor mode, which requires a costly
workaround) and math coprocessor emulation. Coprocessor emulation
is retained in the LAPTOP kernels, but not in the others. Where
it is known that a configuration cannot be run with particular CPUs
(i486 in *MP kernels) remove that support as well. Compile all
kernels with appropriate architecture and tuning flags (reduces
size, makes things faster). Those requiring support for machines
with i386 CPU or lacking coprocessor can use the *SMALL or *TINY
kernels.

reserve some more space for the BSS section than the binary says. This
trick was used to leave room after the kernel's image to copy the symbol
table following the format required by ksyms_init. (It was also used to
workaround a bug in the physical address fields of the binary, but this has
been long fixed.) Yes, the MULTIBOOT_SYMTAB_SPACE option goes away; yay!
Instead, copy the required data after the kernel in a way that avoids having
to reserve space and use the new ksyms_init_explicit function to avoid the
need to construct a minimal ELF image.
Fixes ksyms when using an "unpatched" GRUB (one that does not contain the
fix to honour the "a.out kludge" for ELF images, even when present) -- i.e.
ddb and lkms. As a side effect, the new code is much clearer to read and
digest.
