- i386 will use 64 bits paddr_t for kvm(3), so we will have to discuss on
how to make it work without too much fuzz with pre-64 bits i386 dumps.
- sparse dumps for memory above 4GB.
Eventually, PAE and !PAE kernels core files should be handled by kvm, if
that's what you are asking.
PAE does not affect program core files.

I don't think so; modules that manipulates 32 bits bus_addr_t will likely

could solve that.

LITHIC (but still having modules as possibility), and that did

So either way, it's fine; but please -- i386 and amd64 should share
common grounds. If some want a MONOLITHIC amd64, it's even possible,
although I can't see the point given the arguments ab
kernel). Needs to be xchecked though.
Note that /stand also includes modules that cannot be included inside a
monolithic kernel, like zfs and solaris compat layer. And these makes up
for ~ half the size of /stand (5MiB).

I don't think that's the issue. Running GENERIC is supposed to make
all stable features and functionality available. The question at hand
is whether those features are compiled in (which would be
"monolithic") or loaded as modules (which would be "modular").
Exactly.

you can't use a CAS to assure atomic operation with the hardware TLB,
as
this is, precisely, a shadow PT and not the one used by hardware.

peace knowing that we have a "valid" strnlen() in kernel rather than a

Hmm, I'll have to cross-check that one this afternoon. IIRC, I am
also using the the default "break" command when I am running the

any sense in a MP system, especially for operations that are frequently

waiting for one to finish its TLB flush before they can edit their PD/PT
again... ouch.

Thanks for looking into it!

so this went unnoticed during my tests as the correct /etc/defaults gets
parsed.
I'll add the required code to handle this; thanks for reporting!

based on a context; the old code does
not permit that, unless you build and store the string somewhere,
forcing the caller to *know* that it only keeps a pointer and does not
copy the content. This will get misused, sooner or later.

- are you sure that these have to be
"defined(PAE) || defined(__x86_64__)" ?
- please use "for (i = 0; i < PTP_LEVELS - 1; i++ ) { ... }". I will
have to identify these blocks later when GENERIC will include both PAE
and !PAE pmaps. PTP_LEVELS makes it a lot easier.
That's all for the first quick review :) Thanks for starting the merge
of your branch.

ok, will watchout for it - do you want to do this one yourself ?
Please do :)

Unless you can convince me that your code will do the right

I always wondered whether i386_use_pae should be set for amd64.
Strictly speaking, PAE is enabled when we are running in long mode. I
set the sysctl(7) a while ago for NX regression tests in ATF, but not
the variable. Maybe I should.

a different rule applicable to man pages for
4-clause vs 2-clause BSD? I occasionally see new man pages written with
a 4-clause BSD, however, most newly written code is 2-clause.

ps to reproduce:
- connect to a dom0 system
- try ballooning up or down, with:
sysctl -w machdep.xen.balloon.target=10
All newly created processes will then stay in tstile, and the sysctl
never returns, waiting on "rplq" wait channel.
