Remove extraneous decls.
Add ``const'' to several places.
Allow ``make NOALIAS=1'' to remove IP aliasing.
Merge with OpenBSD - only the Makefiles vary.
We can now survive a compile with
-Wall -Wbad-function-cast -Wcast-align -Wcast-qual
-Winline -Wmissing-declarations -Wmissing-prototypes
-Wnested-externs -Wpointer-arith -Wredundant-decls
-Wshadow -Wstrict-prototypes -Wwrite-strings -Wchar-subscripts
(although the Makefile just contains -Wall).
Note this ONLY affects the function version - the macro version is always
used unless for some reason you put #undef sigismember in your code before
calling it.
PR: 3615
Submitted by: Nanbor Wang <nw1@cs.wustl.edu> (slightly amended patch)
time, but was left at 0. This caused the "can't happen" case in
splz_swi to happen for panics when tsleep() calls splx(safepri)
and there is a SWI_AST pending. This was harmless because the
the error handling happens to be right. Debugging this was tricky
because debugger traps force SWI_AST_MASK on in `cpl'.
there is a natural place to initialize `safepri' in a future commit.
Spinoffs:
- spl0() gets called in the unlikely event that isa is not configured.
- configure() has better control over enabling interrupts.
- it is now less unclear that interrupts aren't actually enabled early.
Rev.1.48 of autoconf.c seems to have done the opposite of what was
intended - moving the isa_configure() call delayed the spl0() side
effect.
Added some comments about the bogons. Removed the splhigh() call since
it is a no-op.
checking the BIOS video mode paramter table. Now syscons uses the
parameter table even if some bits in the table are different from the
current VGA register settings.
Even if comp_vgaregs() finds that the BIOS video parameter table looks
totally unfamiliar to it, syscons allows the user to change the
current video mode to some modes which are based on the VGA 80x25
mode. They are VGA 80x30, VGA 80x50, VGA 80x60. In this case the user
will be warned, during boot, that video mode switching is only
paritally supported on his machine.

this mouse can correctly operate only in the high resolution mode.
If the mouse pointer jumps to the top or left edge or the top-left
corner of the screen, try defining PSM_MSCKLUDGE in the kernel
configuration file. This option will put the mouse in the high
resolution mode during device initialization.
Disallow wait options that are not a combination of the standard POSIX
options WUNTRACED and WNOHANG, as is required by POSIX. BSD doesn't
have any extensions here, but the code was `#ifdef notyet' for some
reason.
interval [VM_MIN_KERNEL_ADDRESS, etext] was used instead of
[btext, etext). Added a comment about this being completely
wrong for LKMs. This only affects interpreting the instructions
after the return to attempt decide the number of args. The
attempt usually fails anyway.
checking was mostly wrong at the boundaries. For the lower limit,
VM_MIN_KERNEL_ADDRESS was used instead of btext and there was an
off-by-(`size' - 1) error. For the upper limit, &etext was used
instead of etext and there was an off-by-1 error. The bugs were
harmless because `size' is not too large and some memory is mapped
just beyond the ends. We still depend on the former to avoid
having to handle the case where the memory range covers the whole
text section, and on the latter to prevent problems when we map
just beyond an end to allow writing an address range that overlaps
the end.
Fixed placement of a nearby comment.
one traditionally reserved for swap devices. The restrictions
should now be the same as the ones for dumpsys(). The restriction
on the partition should be removed someday, and dumpsys() shouldn't
repeat all the checks.
it if the file system is mounted noatime). Not fixed: the access
time is marked at the start of a read() and not marked on successful
completion. I think this should be handled at the vfs level.
Print a better panic message for missing vops. Don't use printf()
before panic(), since the printf()ed part isn't shown by gdb.
This actually loses a little with the current gdb, since gdb just
prints the fmt arg to panic, so %'s aren't expanded. gdb should
fetch the full message from the message buffer if possible.
Fixed default vop function for vop_getpages_desc. It needs to
just return EOPNOTSUPP so that the vnode pager can get the pages
in using a general method. Panicing broke exec'ing of files on
ext2fs file systems. ffs works because it doesn't use the default.
Fixed nearby style bugs.
we won't have double-slashes.
Add support for new port variable MANUAL_PACKAGE_BUILD. If this is
defined as well as the user variable PACKAGE_BUILDING, the port will
be ignored. This is used to mark ports that can be built normally
except on a machine that has a lot of conflicting ports (i.e., our
package building machine).
