ICH7M was separated from ICH6M to allow undocumented MAP value 01b
which was spotted on an ASUS notebook. However, there is also
notebooks with MAP value 01b on ICH6M. This patch re-merges ICH6M and
ICH7M entries and allows MAP value 01b for both.
This problem has been reported and initial patch provided by Jonathan
Dieter.

Hi Jeff,
I tested the PATA support on my old VAIO notebook, and it failed to find
my piix device:
00:07.1 Class 0101: 8086:7111 (rev 01) (prog-if 80 [Master])
Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR- FastB2B-
Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
Latency: 64
Region 4: I/O ports at fc90 [size=16]
This patch adds the pci id to ata_piix.c and things then work as
expected.

sis_init_one() modifies probe_ent->port_flags after allocating and
initializing it using ata_pci_init_native_mode(). This makes port_flags
for the secondary port (probe_ent->pinfo2->flags) go out of sync resulting
in misdetection of device due to incorrectly initialized SCR access flag.
This patch make probe_ent alloc/init happen after the final port flags
value is determined. This is fragile but probe_ent and all the related
mess are scheduled to go away soon for exactly this reason. We just need
to hold everything together till then.
This has been spotted and diagnosed and tested by Patrick McHardy.

The check to see if the firmware drops interrupts during a
SAL_CACHE_FLUSH is done to early in the boot. SAL_CACHE_FLUSH expects
to be able to make PAL calls in virtual mode, on some cell based
machines a fault occurs causing a MCA. This patch moves the check
after mmu_context_init so the TLB and VHPT are properly setup.

The information in MCA records is filled in slightly differently on
Montecito than on Madison/McKinley. Usually, the cache check and bus
check target identifiers have the same address. On Montecito the
cache check and bus check target identifiers can be different if
a corrected error (ie SBE or unconsumed poison data) was encountered and
then an uncorrected error (ie DBE) was consumed. In that case, the
cache check target identifier is the physical address of the DBE (that
caused the MCA to surface) while the bus check target identifier is the
physical address of the SBE. This patch correctly finds the target
identifier that triggered the MCA.
If there are multiple valid cache target identifiers in the same
error record then use the one with the lowest cache level.

Since we already moved to GENERIC_TIME, we should implement alternatives
of old do_gettimeoffset routines to get sub-jiffies resolution from
gettimeofday(). This patch includes:
* MIPS clocksource support (based on works by Manish Lachwani).
* remove unused gettimeoffset routines and related codes.
* remove unised 64bit do_div64_32().
* simplify mips_hpt_init. (no argument needed, __init tag)
* simplify c0_hpt_timer_init. (no need to write to c0_count)
* remove some hpt_init routines.
* mips_hpt_mask variable to specify bitmask of hpt value.
* convert jmr3927_do_gettimeoffset to jmr3927_hpt_read.
* convert ip27_do_gettimeoffset to ip27_hpt_read.
* convert bcm1480_do_gettimeoffset to bcm1480_hpt_read.
* simplify sb1250 hpt functions. (no need to subtract and shift)

In very rare circumstances would we be pruning a merged request and at
the same time delete the implicated cfqq from the rr_list, and not readd
it when the merged request got added. This could cause io stalls until
that process issued io again.
Fix it up by putting the rr_list add handling into cfq_add_rq_rb(),
identical to how pruning is handled in cfq_del_rq_rb(). This fixes a
hang reproducible with fsx-linux.

Partitions are not limited to live within a device. So we should range
check after partition mapping.
Note that 'maxsector' was being used for two different things. I have
split off the second usage into 'old_sector' so that maxsector can be still
be used for it's primary usage later in the function.

If there are no listeners, taskstats_exit_send() just returns because
taskstats_exit_alloc() didn't allocate *tidstats. This is wrong, each
sub-thread should do fill_tgid_exit() on exit, otherwise its ->delays is
not recorded in ->signal->stats and lost.
Q: We don't send TASKSTATS_TYPE_AGGR_TGID when single-threaded process
exits. Is it good? How can the listener figure out that it was actually a
process exit, not sub-thread?

Fix a small memory leak in ubd_config, and clearify the confusion which lead

Then, some little changes not affecting operations -
* move init functions together,
* add a comment about a potential problem in case of some evolution in the block layer,
* mark all initcalls as static __init functions
* mark an used once little function as inline
* document that mconsole methods are all called in process context (was
triggered when checking ubd mconsole methods).

do_ubd is actually just a boolean variable - the way it is used currently is a

Add some comments about requirements for ubd_io_lock and expand its use.
When an irq signals that the "controller" (i.e. another thread on the host,
which does the actual requests and is the only one blocked on I/O on the host)
has done some work, we call again the request function ourselves
(do_ubd_request).
We now do that with ubd_io_lock held - that's useful to protect against
concurrent calls to elv_next_request and so on.
XXX: Maybe we shouldn't call at all the request function. Input needed on
this. Are we supposed to plug and unplug the queue? That code "indirectly"
does that by setting a flag, called do_ubd, which makes the request function
return (it's a residual of 2.4 block layer interface).
Meanwhile, however, merge this patch, which improves things.

This lock protects ubd setup and teardown, so is only used in process context;
beyond that, during such setup memory allocations must be performed and some
generic functions which can sleep must be called (such as add_disk()). So the
only correct solution is to make it a mutex instead of a spin_lock. No other
change is done - this lock must be acquired in different places but it's done
afterwards.

To rethink locking, I needed to understand well what each function does.
While doing this I renamed some:
* ubd_close -> ubd_close_dev (since it pairs with ubd_open_dev)
* ubd_new_disk -> ubd_disk_register (it handles registration with the block
layer - one hopes this makes clearer the difference with ubd_add())

There's a bug in the seqfile show operation for flowlabel objects, where
each hash chain is traversed cumulatively for each element. The following
function is called for each element of each chain:
static void ip6fl_fl_seq_show(struct seq_file *seq, struct ip6_flowlabel *fl)
{
while(fl) {
seq_printf...
fl = fl->next;
}
}
Thus, objects can appear mutliple times when reading
/proc/net/ip6_flowlabel, as the above is called for each element in the
chain.
The solution is to remove the while() loop from the above, and traverse
each chain exactly once, per the patch below. This also removes the
ip6fl_fl_seq_show() function, which does nothing else.

This changes all of the callers of make_ipr_irq to

is then passed to make_ipr_irq. This removes the need for
