[PATCH] null-terminate over-long /proc/kallsyms symbols
Got a customer bug report (https://bugzilla.novell.com/190296) about kernel
symbols longer than 127 characters which end up in a string buffer that is
not NULL terminated, leading to garbage in /proc/kallsyms. Using strlcpy
prevents this from happening, even though such symbols still won't come out
right.
A better fix would be to not use a fixed-size buffer, but it's probably not
worth the trouble. (Modversion'ed symbols even have a length limit of 60.)

This patch removes the foolish assumption that SMP implied local apics.
That assumption is not-true on the Voyager subarch. This makes that

What gets disabled is just an optimization to get better crash dumps so the

[PATCH] ia64: race flushing icache in COW path
There is a race condition that showed up in a threaded JIT environment.
The situation is that a process with a JIT code page forks, so the page is
marked read-only, then some threads are created in the child. One of the
threads attempts to add a new code block to the JIT page, so a
copy-on-write fault is taken, and the kernel allocates a new page, copies
the data, installs the new pte, and then calls lazy_mmu_prot_update() to
flush caches to make sure that the icache and dcache are in sync.
Unfortunately, the other thread runs right after the new pte is installed,
but before the caches have been flushed. It tries to execute some old JIT
code that was already in this page, but it sees some garbage in the i-cache
from the previous users of the new physical page.
Fix: we must make the caches consistent before installing the pte. This is
an ia64 only fix because lazy_mmu_prot_update() is a no-op on all other
architectures.

[MIPS] Do not count pages in holes with sparsemem
With some memory model other than FLATMEM, the single node can
contains some holes so there might be many invalid pages. For
example, with two 256M memory and one 256M hole, some variables
(num_physpage, totalpages, nr_kernel_pages, nr_all_pages, etc.) will
indicate that there are 768MB on this system. This is not desired
because, for example, alloc_large_system_hash() allocates too many

[SPARC]: Fix OF register translations under sub-PCI busses.
There is an implicit assumption in the code that ranges will translate
to something that can fit in 2 32-bit cells, or a 64-bit value. For
certain kinds of things below PCI this isn't necessarily true.
Here is what the relevant OF device hierarchy looks like for one of
the serial controllers on an Ultra5:
Node 0xf005f1e0
ranges:
00000000.
00000000.
00000000.
000001fe.
01000000.
00000000.

02000000.
00000000.
00000000.
000001ff.
00000000.
00000001.
00000000
03000000.
00000000.
00000000.
000001ff.
00000000.
00000001.
00000000
device_type: 'pci'
model: 'SUNW,sabre'
Node 0xf005f9d4
device_type: 'pci'
model: 'SUNW,simba'
Node 0xf0060d24
ranges:
00000010.
00000000 82010810.
00000000.
f0000000 01000000
00000014.
00000000 82010814.
00000000.
f1000000 00800000
name: 'ebus'
Node 0xf0062dac
reg:
00000014.
003083f8.
00000008 --> 0x1ff.
f13083f8
device_type: 'serial'
name: 'su'
So the correct translation here is:
1) Match "su" register to second ranges entry of 'ebus', which translates
into a PCI triplet "
82010814.
00000000.
f1000000" of size
00800000, which
gives us "
82010814.
00000000.
f13083f8".
2) Pass-through "SUNW,simba" since it lacks ranges property
3) Match "
82010814.
00000000.
f13083f8" to third ranges property of PCI
controller node 'SUNW,sabre', and we arrive at the final physical
MMIO address of "0x1fff13083f8".
Due to the 2-cell assumption, we couldn't translate to a PCI 3-cell
value, and we couldn't perform a pass-thru on it either.
It was easiest to just stop splitting the ranges application operation
between two methods, ->map and ->translate, and just let ->map do all
the work. That way it would work purely on 32-bit cell arrays instead
of having to "return" some value like a u64.
It's still not %100 correct because the out-of-range check is still
done using the 64 least significant bits of the range and address.
But it does work for all the cases I've thrown at it so far.
