bzero -> memset

ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

Remove all the __P() from sys (excluding sys/dist)

Replace as much of the hardcoded CACHELINESIZE with
curcpu()->ci_ci.dcache_line_size as I can. With this change, an ofppc kernel
compiled with both PPC_OEA and PPC_OEA64_BRIDGE defined, boots.

fix mistakes in yamt-uio_vmspace changes.

branches: 1.12.2; 1.12.4;
merge yamt-uio_vmspace branch.

- use vmspace rather than proc or lwp where appropriate.
the latter is more natural to specify an address space.
(and less likely to be abused for random purposes.)
- fix a swdmover race.

branches: 1.11.2; 1.11.4; 1.11.6;
Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

merge ktrace-lwp.

bus_dmamem_map: honour BUS_DMA_NOWAIT. noted by Manuel Bouyer.
bus_space_map: always do NOWAIT allocation as it used to be before yamt-km.

we have too many copies!

branches: 1.8.2; 1.8.8;
merge yamt-km branch.
- don't use managed mappings/backing objects for wired memory allocations.
save some resources like pv_entry. also fix (most of) PR/27030.
- simplify kernel memory management API.
- simplify pmap bootstrap of some ports.
- some related cleanups.

Add a dm_maxsegsz public member to bus_dmamap_t. This allows a user of the API
to select the maximum segment size for each bus_dmamap_load (up to the maxsegsz
supplied to bus_dmamap_create). dm_maxsegsz is reset to the value supplied to
bus_dmamap_create when the dmamap is unloaded.

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

Use PAGE_SIZE rather than NBPG.

Remove duplicate #includes, patch contributed in private mail
by Slava Semushin <slava.semushin@gmail.com>.

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".

Thanks to martin@ for the input on testing.

__KERNEL_RCSID()

branches: 1.10.2;
Make this compile with DEBUG defined.

Fix use of an uninitialised variable. This was harmless, other than
spuriously incrementing an interrupt counter.

Management, not managment. Mostly from jmc@openbsd.

Make the imask_t typedef a struct rather than a naked array. The attribute
on the array typedef was contaminating other u_int32_t naked arrays and
affecting their alignment.

Add __HAVE_GENERIC_SOFT_INTERRUPT support.

Make the result an early clobber so gcc won't get clever.

Reduce visible globals. (gt_handle is now gt_memh and is only known to
machdep.c, gt_mainbus.c, and extintr.c)

Make lint happy and use __asm && __volatile.
manipulate netisr via lwarx/stwcx. to get atomicity.

Adapt to powerpc/bus.h changes.

Add preliminary support Marvell (Galileo) Discovery System Controllers.
This code was contributed by Allegro Networks.

Style and cosmetic changes. No binary changes intended.

Part of the interrupt rototill. Use <powerpc/intr.h> and just override
a few things (like imask_t).

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

- finish implementing splraiseipl (and makeiplcookie).
http://mail-index.NetBSD.org/tech-kern/2006/07/01/0000.html
- complete workqueue(9) and fix its ipl problem, which is reported
to cause audio skipping.
- fix netbt (at least compilation problems) for some ports.
- fix PR/33218.

branches: 1.10.4; 1.10.6;
Bring ibm4xx interrupt code up to date:

- generic soft interrupts (ie. use powerpc/softintr.c)
- interrupt event counters (using the ones from powerpc/cpu.h:cpu_info
where appropriate)
- cleanup ibm4xx_intr.h, move implementation details to intr.c

Convert all affected evbppc platforms.

First pass of the new PCI MSI/MSI ABI definitions. (return EOPNOTSUPP for

Add support pci_intr_setattr.
Export non-inline version of pci api for modules (_MODULE is defined).
Fix definition of pc_conf_hook and pc_conf_interrupt.
Switch to using inlines instead of macros.
Switch ibm4xx to use <powerpc/pci_machdep.h>

Change definition of pc_bus_maxdevs to get a void * instead a pci_chipset_tag_t
to match its use in pci_bus_maxdevs. This makes it the same as pci_conf_read
and pci_conf_write.
Change all struct device * to device_t.
[Obviously nothing ever used the first argument to pc_bus_maxdevs since it
could have never worked because it wasn't being passed a pci_chipset_tag_t.]

This contains no marvell specific code now. It now completely hides the
underlying PCI MD implementation. XXX want to move this to
powerpc/include/ someday.

Remove unneeded conditional code.

remove checks for failure after memory allocation calls that cannot fail:

kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.
