kill extra curproc/curlwp definitions that have no chance of working.

(christos)

tuck curproc/curlwp under _KERNEL only (no _KMEMUSER)

(christos)

On NetBSD it's spelled "__NO_STRICT_ALIGNMENT".  Adjust txp_rx_reclaim()
accordingly and structure it like other NetBSD drivers so as to re-use
the original Rx buffer rather than doing a needless free/alloc cycle.

Note this happened to work previously on my Qube2 because IP, TCP, etc.
perform their own alignment checks and react accordingly.  However, it's
not clear that ALL protocols do this yet, so it's better to just do the
safe thing for now.

(thorpej)

protect curcpu/curlwp from _KMEMUSER

(christos)

- Add support for MBUFTRACE.
- Fix an mbuf leak I introduced in rev 1.68 (failed to increment "cnt"
  variable in txp_start(), which subsequently caused txp_tx_reclaim()
  to never run).
- Use the context address pointer in the Tx descriptor to stash the
  pointer to the Tx job software state in a manner like that which
  is used for Rx software state.

(thorpej)

Protect against multiple inclusion.

(thorpej)

Rework previous, so that the real syscall code is not invoked from within
the module_hook code.  Otherwise, if the syscall just happens to be exit()
we will exit while still holding a reference to the hook's localcount, and
nothing will ever release that reference.  Attempts to manually unload the
module will hang indefinitely, as will modstat(8).

PT_GNU_RELRO segments are arranged such that their vaddr + memsz ends
on a linker common page size boundary.  However, if the common page size
used by the linker is less than the VM page size being used by the kernel,
this can end up in the middle of a VM page and when the region is write-
protected, this can cause objects in neighboring .data to get incorrectly
write-protected, resulting in a crash.

Avoid this situation by calculating the end of the RELRO region not by
rounding memsz up to the VM page size, but rather by adding vaddr + memsz
and then truncating to the VM page size.

sys/arch/amigappc/include/bus_defs.h: revision 1.8

gayle wants stride_1swap now, so declare the rest of the bus methods since
we already define them anyway.

(martin)

Pull up following revision(s) (requested by is in ticket #1517):

sys/arch/amiga/dev/gayle_pcmcia.c: revision 1.32

The Gayle interface uses swapped (little-endian) word accesses, so we
need to use the amiga_bus_stride_1swap methods for the word accesses.

sys/kern/sys_select.c: revision 1.42-1.45

PR/54158: Anthony Mallet: poll(2) does not allow polling all possible fds
(hardcoded limit to 1000 + #<open-fds>). Changed to limit by the max of
the resource limit of open descriptors and the above.

Remove the slop code. Suggested by mrg@

Use the max limit (aka maxfiles or the moral equivalent of OPEN_MAX) which
makes poll(2) align with the Posix documentation (which allows EINVAL if
nfds > OPEN_MAX). From: Anthony Mallet

Add slop of 1000 and explain why.

Pull up following revision(s) (requested by mrg in ticket #1512):

sys/external/bsd/drm2/nouveau/nouveau_pci.c: revision 1.24,1.25
(via patch)

Improve nouveau pci attachment code so it waits for the availability of /
before trying to load firmware.
Fixes my PR 54274.

LGTM mrg

list the PCI ID range for new nvidia TU117 and TU116.

adjust the check to simply be >= 0x1580, which is the
first pciid not support.

should fix PR#54600.

Fix comments on root devices.

Fix broken printf(3) %d output for numbers more than two digits, e.g.,

  printf("%d\n", 42) ---> "::" instead of "42"

Our __{,u}modsi3 codes assume that __udivsi3 returns remainder to
%d1 (volatile register). __udivsi3 in libgcc does not, and therefore
mixing them up results in mess.

Retire md(4) in favor of tmpfs provided by module,
though both are not useful for 8MB RAM system...

sun2 kernel is restricted to ~2MB due to bootloader.
It seems that working kernel should be more smaller.

Strip off most kernel options, and provide by kernel modules.
Also add GENERIC kernel for NFS root instead of FFS.

Use BUS_ADDR_{HI,LO}32().

(thorpej)

Support 64-bit DMA addressing on the DP83820, used only when a 64-bit
DMA tag is available.

(thorpej)

Add BUS_ADDR_{LO,HI}32() macros to correctly extract the lower and
upper halves of 64-bit DMA addresses for 32-bit and 64-bit bus_addr_t.
This is a common pattern in modern drivers, so it's a good idea to provide
a common correct definition.

This particular implementation suggested by riastradh@.

Fix another left-over from last year's [pgoyette-compat] work.  This
allows recognition of the oosyscall sequence for amd64.

KMEM_SIZE: append the size_t to the allocated buffer, rather than
prepending, so it doesn't screw up the alignment of the buffer.

split an "a && b" assertion into two so it's clear in the dump which condition
was not true even if both are true by the time the dump is written.

(chs)

in ufsdirhash_free(), only examine dh->dh_onlist after taking the
dirhashlist lock.  if we skip the lock then we might see that
dh_onlist is zero while ufsdirhash_recycle() is still working on
the dirhash.  the symptom I saw was that ufsdirhash_free() would
try to destroy the dh_lock mutex while it was still held.

(chs)

undo previous since config has been fixed

(christos)

use a binary search in _kvm_pa2off().  this helps a lot for sparse dumps,
which can have millions of memory segments.

correct documentation for options TFTPROOT

TFTPROOT does *not* require MEMORY_DISK_IS_ROOT. In fact, it doesn't
work at all when MEMORY_DISK_IS_ROOT is set, because then setroot()
tries to perform dhcp on md0 instead of the network card.

PR/55057: Paul Goyette: Don't use % 6 arithmetic that hurts the brain for
the ifdef state machine, use bits and shifts instead. Also don't forget to
restore the state once an include file ends.

regen for mknative and all platforms.  there are a few things
fixed in this, mostly related to tgmath.h or frexp, and some
generated vs hand-edited white space diffs.

Add missing newline to a diagnostic printf.

Fix MIPS builds by working around an apparent bug in config(8)'s elif
handling.

(thorpej)

Try to fix the build. This is why all those inlines should really be in a
separate file as regular function. The code is too large and hard to manage
this way, and only increases in complexity as time goes by.

Return error values directly where appropriate, instead of using the err

Properly mark netbsd32_compat_43 syscalls that are directly implemented
by calling their compat_43 equivalents.  With these changes, and with
built-in versions of COMPAT_NETBSD32, COMPAT_NOMID, and COMPAT_09, I can
now run a netbsd-0.9 statically linked i386 (32-bit) version of /bin/ls
on a 9.99.x amd64 host!

Addresses PR kern/55047 but more changes coming to handle non-built-in
modules.

Add new ptrace(2) test file

t_ptrace_sigchld - for SIGCHLD handler + ptrace(2).

Right now a single test is enabled (raise(SIGKILL)) and marked as failed
as it never finishes as the child is never collected before exiting the
parent uninterested about its child (SA_NOCLDWAIT).

(kamil)

Add await_collected()

This functions waits for collecting a process.
