Any problems reported by testers have been fixed, and massive
cross-compiling of kernels has shown that any problems that remain
with actually building kernels are not related to this.
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups
model in use for a given platform (__PROG26 vs __PROG32), then pulls
in <arm/types.h>. Change each ARM port to pull in <arm/arm26/types.h>
or <arm/arm32/types.h> as appropriate. Change all references to PROG26
and PROG32 to __PROG26 and __PROG32. Eliminate the opt_progmode.h
header file.
Refuse to clear the modified bit on a page if it has a writeable kernel
mapping. I'm not sure this is the right thing to do, but since further
writes to the page won't set the bit again, it's safer than clearing it,
and makes NFS writes work properly.
Add debugging code for modified-bit emulation, which checksums
allegedly-unmodified pages to see if they're _really_ unmodified.
Disabled by default because it's slow.
In the process, fix a bug in pv_release whereby the modified bit for a
page got cleared when its last mapping was removed. This seems to finish
the NFS write fixes started by the first change above.
Include <ddb/db_access.h> for db_read_bytes etc prototypes.
Add prototype for db_trapper().
Move prototypes for "machine" subcommands to db_machdep.h.
db_machdep.h:
Add prototypes for "machine" subcommands.
On platforms which load the kernel sans symbols directly from firmware
(possibly in e.g. S-Record format), call ddb_init() with empty arguments,
so that it will search any compiled in SYMTAB_SPACE. On all other platforms,
if __ELF__, also call ddb_init() with empty arguments until ELF bootloaders
which pass symbol information are ready.
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.
Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.
pmap_kenter_pa. pmap(9) says unmanage mappings don't get referenced/modified
tracking, and this seems to stop me getting a panic while starting up with
root on NFS.
