[MIPS] Rename CONFIG_BUILD_ELF64 into KBUILD_64BIT_SYM32
This patch renames it for 3 reasons:
- "CONFIG" pattern is used by Kconfig. Now this macro is
no more defined by Kconfig but by Kbuild itself make this
clear by translating "CONFIG" into "KBUILD".
- "ELF32" word is improper because it is irrelevant to ELF
format and it makes confusion with CONFIG_BOOT_ELF32. So
translate it with SYM32.
- Add "64BIT" part to make clear that this macro implies a
64 bits kernel.

[IPv6]: Fix ICMPv6 redirect handling with target multicast address
When the ICMPv6 Target address is multicast, Linux processes the
redirect instead of dropping it. The problem is in this code in
ndisc_redirect_rcv():
if (ipv6_addr_equal(dest, target)) {
on_link = 1;
} else if (!(ipv6_addr_type(target) & IPV6_ADDR_LINKLOCAL)) {
ND_PRINTK2(KERN_WARNING
"ICMPv6 Redirect: target address is not
link-local.\n");
return;
}
This second check will succeed if the Target address is, for example,
FF02::1 because it has link-local scope. Instead, it should be checking
if it's a unicast link-local address, as stated in RFC 2461/4861 Section
8.1:
- The ICMP Target Address is either a link-local address (when
redirected to a router) or the same as the ICMP Destination
Address (when redirected to the on-link destination).
I know this doesn't explicitly say unicast link-local address, but it's
implied.
This bug is preventing Linux kernels from achieving IPv6 Logo Phase II
certification because of a recent error that was found in the TAHI test
suite - Neighbor Disovery suite test 206 (v6LC.2.3.6_G) had the
multicast address in the Destination field instead of Target field, so
we were passing the test. This won't be the case anymore.
The patch below fixes this problem, and also fixes ndisc_send_redirect()
to not send an invalid redirect with a multicast address in the Target
field. I re-ran the TAHI Neighbor Discovery section to make sure Linux
passes all 245 tests now.

[TCP]: Fix fastpath_cnt_hint when GSO skb is partially ACKed
When only GSO skb was partially ACKed, no hints are reset,
therefore fastpath_cnt_hint must be tweaked too or else it can
corrupt fackets_out. The corruption to occur, one must have
non-trivial ACK/SACK sequence, so this bug is not very often
that harmful. There's a fackets_out state reset in TCP because
fackets_out is known to be inaccurate and that fixes the issue
eventually anyway.
In case there was also at least one skb that got fully ACKed,
the fastpath_skb_hint is set to NULL which causes a recount for
fastpath_cnt_hint (the old value won't be accessed anymore),
thus it can safely be decremented without additional checking.

It turns out that there are a few other five-second timers in the
kernel, and if the timers get in sync, the load-average can get
artificially inflated by events that just happen to coincide.
So just offset the load average calculation it by a timer tick.
Noticed by Anders Boström, for whom the coincidence started triggering
on one of his machines with the JBD jiffies rounding code (JBD is one of
the subsystems that also end up using a 5-second timer by default).

VT_WAITACTIVE: Avoid returning EINTR when not necessary
We should generally prefer to return ERESTARTNOHAND rather than EINTR,
so that processes with unhandled signals that get ignored don't return
EINTR.
This can help with X startup issues:
Fatal server error:
xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call
although the real fix is having the X server always retry EINTR
regardless (since EINTR does happen for signals that have handlers
installed). Keithp has a patch for that.

Fix non-terminated PCI match table in PowerMac IDE
The PCI device table in the powermac IDE driver isn't properly
terminated. Depending on how your kernel is linked and other random
factors, you can end up with this driver matched against any other PCI
device in your system, possibly crashing at boot.
Thanks to Heikki for tracking this down with me, the bug have been there
for some time, though it rarely hurts due to luck. In this case, the
switch from .22 to .23-rc9 is causing it to show up due to differences
in the resulting layout of .data I suppose.

xen: disable split pte locks for now
When pinning and unpinning pagetables, we must protect them against
being used by other CPUs, lest they see the pagetable in an
intermediate read-only-but-not-pinned state.
When using split pte locks, doing this properly would require taking
all the pte locks for the pagetable while pinning, but this may overflow
the PREEMPT_BITS part of the preempt counter if the process has mapped
more than about 512M of memory.
However, failing to take the pte locks causes write-protect faults when
the pageout code is trying to clear the Access bit on a pte which is part
of a freshy created and still being pinned process after fork.
This is a short-term fix until the problem is solved properly.

Remove unnecessary cast in prefetch()
It is ok to call prefetch() function with NULL argument, as specifically
commented in include/linux/prefetch.h. But in standard C, it is invalid
to dereference NULL pointer (see C99 standard 6.5.3.2 paragraph 4 and
note #84).
prefetch() has a memory reference for its argument.
Newer gcc versions (4.3 and above) will use that to conclude that "x"
argument is non-null and thus wreaking havok everywhere prefetch() was
inlined.
Fixed by removing cast and changing asm constraint.
[ It seems in theory gcc 4.2 could miscompile this too; although no
cases known. In 2.6.24 we should probably switch to
__builtin_prefetch() instead, but this is a simpler fix for now.

Fix sys_remap_file_pages BUG at highmem.c:15!
Gurudas Pai reports kernel BUG at arch/i386/mm/highmem.c:15! below
sys_remap_file_pages, while running Oracle database test on x86 in 6GB
RAM: kunmap thinks we're in_interrupt because the preempt count has
wrapped.
That's because __do_fault expected to unmap page_table, but one of its
two callers do_nonlinear_fault already unmapped it: let do_linear_fault
unmap it first too, and then there's no need to pass the page_table arg
down.
Why have we been so slow to notice this? Probably through forgetting
that the mapping_cap_account_dirty test means that sys_remap_file_pages
nowadays only goes the full nonlinear vma route on a few memory-backed
filesystems like ramfs, tmpfs and hugetlbfs.
[ It also depends on CONFIG_HIGHPTE, so it becomes even harder to
trigger in practice. Many who have need of large memory have probably
migrated to x86-64..

[SPARC64]: Temporary workaround for PCI-E slot on T1000.
The PCI-E slot on T1000 connects directly to the Fire PCI chip with no
intervening bridges visible in the OBP tree.
Unfortunately the bus numbering of the device in that slot is
different (2) from the PCI host controller (0), and thus the
pci_bus_{read,write}_config_*() calls don't work out.
Complicating things further the Fire PCI controller has no config
space it responds to either.
For now treat this case specially so that devices in the slot work.
Longer term we need to perhaps cons up a dummy bridge between the Fire
and the PCI-E slot so that the bus hierarchy is complete inside of the
kernel and thus the bus numbering all works out right.

[SPARC64]: Fix missing load-twin usage in Niagara-1 memcpy.
For the case where the source is not aligned modulo 8
we don't use load-twins to suck the data in and this
kills performance since normal loads allocate in the
L1 cache (unlike load-twin) and thus big memcpys swipe
the entire L1 D-cache.
We need to allocate a register window to implement this
properly, but that actually simplifies a lot of things
as a nice side-effect.

[TCP]: secure_tcp_sequence_number() should not use a too fast clock
TCP V4 sequence numbers are 32bits, and RFC 793 assumed a 250 KHz clock.
In order to follow network speed increase, we can use a faster clock, but
we should limit this clock so that the delay between two rollovers is
greater than MSL (TCP Maximum Segment Lifetime : 2 minutes)
Choosing a 64 nsec clock should be OK, since the rollovers occur every
274 seconds.

x86_64: increase VDSO_TEXT_OFFSET for ancient binutils
For some reason old binutils genertate larger headers so increase the text
offset of the vdso to avoid linker errors.
Roland McGrath explains:
"There are extra symbols in the '.dynsym' section that are responsible
for the size difference (They also cause corresponding inflation in
'.gnu.version')
Older ld's wrongly generated these unneeded symbols in .dynsym. This
was fixed not all that long ago (2006); binutils-2.17.50.0.6 might be
the first fixed version, but I have not verified for sure where the
cutoff was.
The unneeded symbols et al from old ld add almost 700 bytes excess.
This limits fairly tightly the amount by which the actual text and
data in the vDSO can grow in the future without pushing the whole
file over 4kb. If it does grow later on, we should consider changing
the layout with a config option or something to pack it better
without that padding, when building the kernel with newer binutils."

[POWERPC] Fix xics set_affinity code

In a desperate attempt to get a changelog entry in 2.6.23, I took a look
into it.
It turns out we are passing a real and not a virtual irq into
get_irq_server. This works for the case where hwirq < NR_IRQS and we
set virq = hwirq. In my case however hwirq = 590082 and we try and
access irq_desc[590082], slightly past the end at 512 entries.
Lucky we ship lots of memory with our machines.
