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."

This reverts commit
b394e43e995d08821588a22561c6a71a63b4ff27.
Lachlan McIlroy says:
It tried to fix an issue where log replay is replaying an inode cluster
initialisation transaction that should not be replayed because the inode
cluster on disk is more up to date. Since we don't log file sizes (we
rely on inode flushing to get them to disk) then we can't just replay
all the transations in the log and expect the inode to be completely
restored. We lose file size updates. Unfortunately this fix is causing
more (serious) problems than it is fixing.

i386: remove bogus comment about memory barrier
The comment being removed by this patch is incorrect and misleading.
In the following situation:
1. load ...
2. store 1 -> X
3. wmb
4. rmb
5. load a <- Y
6. store ...
4 will only ensure ordering of 1 with 5.
3 will only ensure ordering of 2 with 6.
Further, a CPU with strictly in-order stores will still only provide that
2 and 6 are ordered (effectively, it is the same as a weakly ordered CPU
with wmb after every store).
In all cases, 5 may still be executed before 2 is visible to other CPUs!
The additional piece of the puzzle that mb() provides is the store/load
ordering, which fundamentally cannot be achieved with any combination of
rmb()s and wmb()s.
This can be an unexpected result if one expected any sort of global ordering
guarantee to barriers (eg. that the barriers themselves are sequentially
consistent with other types of barriers). However sfence or lfence barriers
need only provide an ordering partial ordering of memory operations -- Consider
that wmb may be implemented as nothing more than inserting a special barrier
entry in the store queue, or, in the case of x86, it can be a noop as the store
queue is in order. And an rmb may be implemented as a directive to prevent
subsequent loads only so long as their are no previous outstanding loads (while
there could be stores still in store queues).
I can actually see the occasional load/store being reordered around lfence on

Fix bogus PCI quirk for e100
Linas reported me that some machines were crashing at boot in

of bad things to happen on architectures where PCI BARs don't directly

This fixes it by using the proper PCI resources instead which is possible
since the quirk has been moved by a previous commit to happen late enough

The check is doubly-wrong because all that a write() can be is a
sendmsg() call with a NULL msg_control and a single entry iovec. No
special semantics should be assigned to it, therefore the zero length
check should be removed entirely.
This matches the behavior of BSD and several other systems.

Revert "x86-64: Disable local APIC timer use on AMD systems with C1E"
This reverts commit
e66485d747505e9d960b864fc6c37f8b2afafaf0, since
Rafael Wysocki noticed that the change only works for his in -mm, not in
mainline (and that both "noapictimer" _and_ "apicmaintimer" are broken
on his hardware, but that's apparently not a regression, just a symptom
of the same issue that causes the automatic apic timer disable to not
work).
It turns out that it really doesn't work correctly on x86-64, since
x86-64 doesn't use the generic clock events for timers yet.
Thanks to Rafal for testing, and here's the ugly details on x86-64 as
per Thomas:
"I just looked into the code and the logic vs. noapictimer on SMP is
completely broken.
On i386 the noapictimer option not only disables the local APIC
timer, it also registers the CPUs for broadcasting via IPI on SMP
systems.
The x86-64 code uses the broadcast only when the local apic timer is
active, i.e. "noapictimer" is not on the command line. This defeats
the whole purpose of "noapictimer". It should be there to make boxen
work, where the local APIC timer actually has a hardware problem,
e.g. the nx6325.
The current implementation of x86_64 only fixes the ACPI c-states
related problem where the APIC timer stops in C3(2), nothing else.
On nx6325 and other AMD X2 equipped systems which have the C1E
enabled we run into the following:
PIT keeps jiffies (and the system) running, but the local APIC timer
interrupts can get out of sync due to this C1E effect.
I don't think this is a critical problem, but it is wrong
nevertheless.
I think it's safe to revert the C1E patch and postpone the fix to the
clock events conversion."
On further reflection, Thomas noted:
"It's even worse than I thought on the first check:
"noapictimer" on the command line of an SMP box prevents _ONLY_ the
boot CPU apic timer from being used. But the secondary CPU is still
unconditionally setting up the APIC timer and uses the non
calibrated variable calibration_result, which is of course 0, to
setup the APIC timer. Wreckage guaranteed."
so we'll just have to wait for the x86 merge to hopefully fix this up
for x86-64.

x86-64: Disable local APIC timer use on AMD systems with C1E
commit
3556ddfa9284a86a59a9b78fe5894430f6ab4eef titled
[PATCH] x86-64: Disable local APIC timer use on AMD systems with C1E
solves a problem with AMD dual core laptops e.g. HP nx6325 (Turion 64
X2) with C1E enabled:
When both cores go into idle at the same time, then the system switches
into C1E state, which is basically the same as C3. This stops the local
apic timer.
This was debugged right after the dyntick merge on i386 and despite the
patch title it fixes only the 32 bit path.
x86_64 is still missing this fix. It seems that mainline is not really
affected by this issue, as the PIT is running and keeps jiffies
incrementing, but that's just waiting for trouble.
-mm suffers from this problem due to the x86_64 high resolution timer
patches.
This is a quick and dirty port of the i386 code to x86_64.
I spent quite a time with Rafael to debug the -mm / hrt wreckage until
someone pointed us to this. I really had forgotten that we debugged this
half a year ago already.

Add explicit zeroing to "envp" array in device 'show' method
As Stephen Hemminger says, this is a "belt and suspenders" patch that
zeroes the envp array at allocation time, even though all the users
should NULL-terminate it anyway (and we've hopefully fixed everybody
that doesn't do that).
And we'll apparently clean the whole envp thing up for 2.6.24 anyway.
But let's just be robust, and do both this *and* make sure that all
users are doing the right thing.

The commit
8b6f50ef1d5cc86b278eb42bc91630fad455fb10 seems to have
been affected by a mismerge of a duplicate patch
(
d054b36ffd302ec65aabec16a0c60ddd9e6b5a62) - both the
spufs_dir_contents and spufs_dir_nosched_contents have been given
write-only signal notification files.
This change reverts the spufs_dir_contents array to use the
readable signal notification file implementation.

SCTP : Add paramters validity check for ASCONF chunk
If ADDIP is enabled, when an ASCONF chunk is received with ASCONF
paramter length set to zero, this will cause infinite loop.
By the way, if an malformed ASCONF chunk is received, will cause
processing to access memory without verifying.
This is because of not check the validity of parameters in ASCONF chunk.
This patch fixed this.

SCTP: Discard OOTB packetes with bundled INIT early.
RFC 4460 and future RFC 4960 (2960-bis) specify that packets
with bundled INIT chunks need to be dropped. We currenlty do
that only after processing any leading chunks. For OOTB chunks,
since we already walk the entire packet, we should discard packets
with bundled INITs.
There are other chunks chunks that MUST NOT be bundled, but the spec
is silent on theire treatment. Thus, we'll leave their teatment
alone for the moment.

While processing OOTB chunks as well as chunks with an invalid

or didn't mark the packet for discard correctly.
