will increase the overhead of queueing a command, but some recent bug reports
make me believe that AAP isn't really working and that we are losing some
SCBs from the input queue. Hopefully this will cure that problem.
Fix some bugs in the error recovery code. Mainly these could cause us to
inadvertantly forget to untimeout an SCB that was recovered causing later
confusion.
to coredump previously since it (somewhat uniquely) is setuid and forks
without execing, and thus without passing P_SUGID the child could
coredump and possibly divulge sensitive information (such as encrypted
passwords from the passwd database).

etc/make.conf:
Nuked HAVE_FPU option.
lib/msun/Makefile:
Always build the i387 objects. Copy the i387 source files at build
time so that the i387 objects have different names. This is simpler
than renaming the files in the cvs repository or repeating half of
bsd.lib.mk to add explicit rules.
lib/msun/src/*.c:
Renamed all functions that have an i387-specific version by adding
`__generic_' to their names.
lib/msun/src/get_hw_float.c:
New file for getting machdep.hw_float from the kernel.
sys/i386/include/asmacros.h:
Abuse the ENTRY() macro to generate jump vectors and associated code.
This works much like PIC PLT dynamic initialization. The PIC case is
messy. The old i387 entry points are renamed. Renaming is easier
here because the names are given by macro expansions.
in the route. This allows us to remove the unconditional setting of the
pipesize in the route, which should mean that SO_SNDBUF and SO_RCVBUF
should actually work again. While we're at it:
- Convert udp_usrreq from `mondo switch statement from Hell' to new-style.
- Delete old TCP mondo switch statement from Hell, which had previously
been diked out.
is administratively downed, all routes to that interface (including the
interface route itself) which are not static will be deleted. When
it comes back up, and addresses remaining will have their interface routes
re-added. This solves the problem where, for example, an Ethernet interface
is downed by traffic continues to flow by way of ARP entries.
clusters greater than one page in length by calling contigmalloc1().
This uses a helper process `mclalloc' to do the allocation if
the system runs out at interrupt time to avoid calling contigmalloc
at high spl. It is not yet clear to me whether this works.
sb_max * MCLBYTES / (MSIZE + MCLBYTES)
used in sbreserve() to overflow, causing all socket creation attempts
to fail. Force the calculation to use u_quad_t's, which makes overflow
less likely.
"boot.config" (relative to the root directory on the 'a' partition
on the first BSD slice) if it exists. If it doesn't exist, then
the only visible changes should be that the kernel name isn't reset
to "/kernel" after looking it up fails and that the default name
is now "kernel".
The new function readfile() can be used for other things:
- reading help messages.
- reading splash screens.
- reading userconfig info.
Changed it from 4 to 16 for i386's. It can be anything for i386's,
but compiler options limit it to a power of 2, and assembler and
linker deficiencies limit it to a small power of 2 (<= 16).
We use 16 in the kernel to get smaller tables (see Makefile.i386 and
<machine/asmacros.h>). We still use the default of 4 in user mode.
Use HISTCOUNTER instead of (*kcount) in the definition of KCOUNT()
for consistency with other macros.
- *fs_init routines now take a "struct vfsconf * vfsp" pointer
as an argument.
- Use the correct type for cookies.
- Update function prototypes.

Call vget/VOP_UNLOCK with the correct number of
arguments. Call vn_lock where appropriate.
vfs_goneall is now replaced by VOP_REVOKE.

It now correctly reports the total buffer space available.

the rest of the routine, it looks like this is a typo,
and it really should have been "1" instead of "i".

filed in the hardware SCB not changing during the course of a transaction.
Since the sequencer now DMAs the hardware SCB back up to the host when it
detects a residual, this is no longer the case. I added a field to the
"software" scb to mirror this information and it is now used for doing the
residual calculation.
When setting the HCNT registers, do so in ascending order.
When performing tagged queueing in non-paging mode, also check the
disconnected bit in the SCB as extra sanity during a reconection.
Make the labels in the DMA routine more sane.
When doing a DMA, if we see the DMADONE condition come true, we can
simply turn of the DMA enable bits in DFCNTRL without testing the FIFO
state as HDONE is true when DMADONE is true and this emplies the FIFO is
empty.
These changes clear up the data overrun error messages and seem to prevent
the "timed out in data-in phase" problems.
