[PATCH] SVGATextMode fix
Fix bug 5441.
I didn't know about messy programs like svgatextmode... Couldn't this be
integrated in some linux/drivers/video/console/svgacon.c ?... So because
of the existence of the svgatextmode program, the kernel is not supposed to
touch to CRT_OVERFLOW/SYNC_END/DISP/DISP_END/OFFSET ?
Disabling the check in vgacon_resize() might help indeed, but I'm really
not sure whether it will work for any chipset: in my patch, CRT registers
are set at each console switch, since stty rows/cols apply to consoles
separately...
The attached solution is to keep the test, but if it fails, we assume that
the caller knows what it does (i.e. it is svgatextmode) and then disable
any further call to vgacon_doresize. Svgatextmode is usually used to
_expand_ the display, not to shrink it. And it is harmless in the case of
a too big stty rows/cols: the display will just be cropped. I tested it on
my laptop, and it works fine with svgatextmode.
A better solution would be that svgatextmode explicitely tells the kernel
not to care about video timing, but for this an interface needs be defined
and svgatextmode be patched.

[PATCH] list: add missing rcu_dereference on first element
It seems that all the list_*_rcu primitives are missing a memory barrier
on the very first dereference. For example,
#define list_for_each_rcu(pos, head) \
for (pos = (head)->next; prefetch(pos->next), pos != (head); \
pos = rcu_dereference(pos->next))
It will go something like:
pos = (head)->next
prefetch(pos->next)
pos != (head)
do stuff
We're missing a barrier here.
pos = rcu_dereference(pos->next)
fetch pos->next
barrier given by rcu_dereference(pos->next)
store pos
Without the missing barrier, the pos->next value may turn out to be stale.
In fact, if "do stuff" were also dereferencing pos and relying on
list_for_each_rcu to provide the barrier then it may also break.
So here is a patch to make sure that we have a barrier for the first
element in the list.

[SPARC64]: Fix boot failures on SunBlade-150
The sequence to move over to the Linux trap tables from
the firmware ones needs to be more air tight. It turns
out that to be %100 safe we do need to be able to translate
OBP mappings in our TLB miss handlers early.
In order not to eat up a lot of kernel image memory with
static page tables, just use the translations array in
the OBP TLB miss handlers. That solves the bulk of the
problem.
Furthermore, to make sure the OBP TLB miss path will work
even before the fixed MMU globals are loaded, explicitly
load %g1 to TLB_SFSR at the beginning of the i-TLB and
d-TLB miss handlers.
To ease the OBP TLB miss walking of the prom_trans[] array,
we sort it then delete all of the non-OBP entries in there
(for example, there are entries for the kernel image itself
which we're not interested in at all).
We also save about 32K of kernel image size with this change.
Not a bad side effect :-)
There are still some reasons why trampoline.S can't use the
setup_trap_table() yet. The most noteworthy are:
1) OBP boots secondary processors with non-bias'd stack for
some reason. This is easily fixed by using a small bootup
stack in the kernel image explicitly for this purpose.
2) Doing a firmware call via the normal C call prom_set_trap_table()
goes through the whole OBP enter/exit sequence that saves and
restores OBP and Linux kernel state in the MMUs. This path
unfortunately does a "flush %g6" while loading up the OBP locked
TLB entries for the firmware call.
If we setup the %g6 in the trampoline.S code properly, that
is in the PAGE_OFFSET linear mapping, but we're not on the
kernel trap table yet so those addresses won't translate properly.
One idea is to do a by-hand firmware call like we do in the
early bootup code and elsewhere here in trampoline.S But this
fails as well, as aparently the secondary processors are not
booted with OBP's special locked TLB entries loaded. These
are necessary for the firwmare to processes TLB misses correctly
up until the point where we take over the trap table.
This does need to be resolved at some point.
