early MD and late MI files must be split up so that vers.o can sneak
between. Issue spotted by bluhm, repair discussed with miod
|
|
having it linked last is bad (on at least i386 and amd64) because the lapic
is mapped over the start of the data segment -- savecore(8) then reads the
version string for a fixed buffer space, and reads into the lapic area
causing unintended side-effects (at least on Intel X5570 and X5680)
found by pedro, discussed with kettenis and mpf and miod

implement them, and they are of questionable usefulness.

kernel, currently limited to low-hanging fruit: these variables were used
by bus_dma to specify the range in which to allocate memory, back when
uvm_pglistalloc() was stupid and would not walk the vm_physseg[].
Nowadays, except on some platforms for early initialization, these variables
are not used, or do not need to be global variables. Therefore:
- remove `extern' declarations of avail_start and avail_end (or close cousins,
such as arm physical_start and physical_end) from files which no longer need
to use them.
- make them local variables whenever possible.
- remove them when they are assigned to but no longer used.

is no easily available physical information outside of the stored
disklabel just make it a synonym for DIOCGDINFO.
Commit on the theory it is unlikely to harm, and fallout can be
addressed in the mass re-compile that will follow j2k10.
Should allow auto-allocation of disks to work with all devices.

take all interfaces down, via their xxstop routines. Claudio and I have
verified that none of the shutdown hooks do much extra beyond what xxstop
was already doing; it is largely a pile of junk.

max-baud-rate hint. Adjust TTYHOG (the nearly full logic) to this new
situation. The larger buffers are required by the very high speed
KDDI devices in Japan (CF com, or USB ucom) so those are the only two
drivers which currently ask for a larger buffer size.

it defines. In some cases, this means pulling in uvm.h or pcb.h
instead, but most of the inclusions were just noise. Tested on
alpha, amd64, armish, hppa, i386, macpcc, sgi, sparc64, and vax,
mostly by krw and naddy.

a fat kernel (GERERIC or GENERIC.MP) into a temporary dir, then extract some
variables using make -V, and after some more singing and dancing use this
full and (more) correct list of files with ctags. Don't read this code.

We cannot yet get at vax/subr.s via files.vax because rdsetroot doesn't
like it when the "start" symbol isn't in the first page of the executable.
subr.s will have to be merged into locore.S later on, when other problems
with ENTRY() are solved (says Miod)

the differences between these files. You will need a newer config(8) binary
to be able to build kernels.
ok kettenis miod

result: kernels built without 'make depend'-provided information
(ie. the .depend file) are more likely to have their *.[Ss] file
compilations track changes to *.h files.
The "*.o: assym.h" dependencies listed are gotten from reading the
.depend output --- from the biggest kernel possible (ie. GENERIC.MP).
When an architecture changes in a substantial way (new .[sS] files),
the list should be updated in the prettiest way possible.
This is not encouraging people to skip 'make depend'; other issues are
not resolved and may be solved later with a change guenther is working
on. You can still screwed really easily, so continue running make
depend as config tells you.
Idea from a discussion with drahn
ok drahn, kettenis likes the idea too

handle special .[sS] files in a portable way

two directories. in reality, because of how we place files, it has four:
.../arch/A, .../arch/A/A, .../arch/M, and .../arch/M/M
formalize this A/A and M/M scheme directly in the Makefiles, which makes
them a lot more similar
drahn likes the idea a lot
