This is the second version of a new driver for the hardware monitoring features
of the Fintek F71882FG and F71883FG Super-I/O chips. This version has several
small fixes for flaws discovered during the review of the first version.
This version of the driver does not support the pwm part of these chips (yet).
I'll first design a sysfs api for this and post that for discussion, and then
implement pwm support as an incremental patch over this one.
This driver supports all sensors of this chip, except for the vid inputs. The
vid inputs are somewhat documented in the datasheet, but I know nothing about
vid/vrm stuff. Help with this would be much appreciated.

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.

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.

Async signals should not be reported as sent by current in audit log. As
it is, we call audit_signal_info() too early in check_kill_permission().
Note that check_kill_permission() has that test already - it needs to know
if it should apply current-based permission checks. So the solution is to
move the call of audit_signal_info() between those.
Bogosity in question is easily reproduced - add a rule watching for e.g.
kill(2) from specific process (so that audit_signal_info() would not
short-circuit to nothing), say load_policy, watch the bogus OBJ_PID entry
in audit logs claiming that write(2) on selinuxfs file issued by
load_policy(8) had somehow managed to send a signal to syslogd...

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).

The PCI device table in the powermac IDE driver isn't properly

device in your system, possibly crashing at boot.
Thanks to Heikki for tracking this down with me, the bug have been there

switch from .22 to .23-rc9 is causing it to show up due to differences

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.
