[PATCH] sys_pselect7 vs compat_sys_pselect7 uaccess error handling
758333458aa719bfc26ec16eafd4ad3a9e96014d fixes the not checked copy_to_user
return value of compat_sys_pselect7. I ran into this too because of an old
source tree, but my fix would look quite a bit different to Andi's fix.
The reason is that the compat function IMHO should behave the very same as
the non-compat function if possible. Since sys_pselect7 does not return
-EFAULT in this specific case, change the compat code so it behaves like
sys_pselect7.

USB: use MII hooks only if CONFIG_MII is enabled
Fix mcs7830 patch
The recent mcs7830 update to make the MII support sharable goofed various
pre-existing configurations in two ways:
- it made the usbnet infrastructure reference MII symbols even
when they're not needed in the kernel being built
- it didn't enable MII along with the mcs7830 minidriver
This patch fixes these two problems.
However, there does seem to be a Kconfig reverse dependency bug in that MII
gets wrongly enabled in some cases (like USBNET=y and USBNET_MII=n); I think
I've noticed that same problem in other situations too. So the result can
mean kernels being bloated by stuff that's needlessly enabled ... better
than wrongly being disabled, but contributing to bloat.

V4L/DVB (4751): Fix DBV_FE_CUSTOMISE for card drivers compiled into kernel
When a front-end is disabled, card drivers that use it are compiled with
a stub version of the front-end's attach function. This way they have no
references to the front-end's code and don't need it to be loaded.
If a card driver is compiled into the kernel, and a front-end is a
module, then that front-end is effectively disabled wrt the card driver.
In this case, the card driver should get the stub version. This was not
happening.
The stub vs real attach function selection is changed so that when the
front-end is a module the real attach function is only used if the card
driver is a module as well. This means a module front-end will be
supported by card drivers that are modules and not supported by card
drivers compiled into the kernel.

The IR chip has no address decoding, so the IR data is always present in
the high byte when doing a read from the saa7146 chip. This means that
the DEBI address used is irrelevant to the IR decoding logic.
DEBI addresses 0x1XXX are mapped to the registers on the CI module
itself, but only the lowest two bits are actually used (see EN50221,
section A.2.2.1), meaning that 0x1234 is equivalent to 0x1000 which maps
to register 0 (the data register). A read from the data register is
supposed to be preceded by a read from the size register, so some CI
modules will be confused (the AlphaCrypt CAM will hang completely).
The attached patch changes the address used when reading the IR data to
use 0x4000 instead. This is the CI version address, which is a safer
default, works with the AlphaCrypt CAM and matches the behaviour of the
Windows driver (AFAIK).

objdump of filemap.o shows gcc 4.1.0 emitting "mr r5,r13 ... ld r9,416(r5)"

"ld r9,416(r13)"; I've seen other gcc4s do the same, but perhaps not gcc3s.
So, if the task is preempted and rescheduled on a different cpu in between

Presumably much worse could happen elsewhere, though that split is rare.

The 10Gigabit ethernet device drivers appear to be able to chew
up all 256MB of TCE mappings on pSeries systems, as evidenced by

Some experimentation indicates that this is essentially because
one 1500 byte ethernet MTU gets mapped as a 64K DMA region when
the large 64K pages are enabled. Thus, it doesn't take much to
exhaust all of the available DMA mappings for a high-speed card.
This patch changes the iommu allocator to work with its own
unique, distinct page size. Although the patch is long, its
actually quite simple: it just #defines a distinct IOMMU_PAGE_SIZE
and then uses this in all the places that matter.
As a side effect, it also dramatically improves network performance
on platforms with H-calls on iommu translation inserts/removes (since
we no longer call it 16 times for a 1500 bytes packet when the iommu HW
is still 4k).
In the future, we might want to make the IOMMU_PAGE_SIZE a variable

[POWERPC] Fix rmb() for e500-based machines it
The e500 core generates an illegal instruction exception when it tries
to execute the lwsync instruction, which we currently use for rmb().
This fixes it by using the LWSYNC macro, which turns into a plain sync
on 32-bit machines.

- A test was inverted causing the palette hack to never work
(no device node was passed down to the init function)
- Some cards seem to have their assigned-addresses property in a random
order, thus we need to try using of_get_pci_address() first, which will
fail if it's not a PCI device, and fallback to of_get_address() in that
case. of_get_pci_address() properly parsees assigned-addresses to test
the BAR number and thus will get it right whatever the order is.
- Some cards (like GXT4500) provide a linebytes of 0xffffffff in the
device-tree which does no good. This patch handles that by using the
screen width when that happens. (Also fixes btext.c while at it).
- Add detection of the GXT4500 in addition to the GXT2000 for the
palette hacks (we use the same hack, palette is linear in register space
at offset 0x6000).

[PATCH] bcm43xx: fix unexpected LED control values in BCM4303 sprom
The bcm43xx driver uses 4 locations in the devices sprom to determine
the behavior of the leds. Certain defaults are assigned if all bits are
set in those locations. On at least one BCM4303 chip, the sprom contains
values other than the default, which executes an assertion placed in the
default case of a following switch statement. This patch makes the leds
on the above mentioned interface behave correctly. In addition, it limits
the number of logged messages to 20 for the case of unexpected values in
the sprom locations.

This fixes a netdev watchdog timeout problem.
The software needs to call netif_tx_disable before running the
hardware calibration code. The problem condition can be shown by the
following timegraph.
|---5secs - ~10 jiffies time---|---|OOPS
^ ^
last real TX periodic work stops netif
At OOPS, the following happens:
The watchdog timer triggers, because the timeout of 5secs
is over. The watchdog first checks for stopped TX.
_Usually_ TX is only stopped from the TX handler to indicate
a full TX queue. But this is different. We need to stop TX here,
regardless of the TX queue state. So the watchdog recognizes
the stopped device and assumes it is stopped due to full
TX queues (Which is a _wrong_ assumption in this case). It then
tests how far the last TX has been in the past. If it's more than
5secs (which is the case for low or no traffic), it will fire
a TX timeout.

[PATCH] hostap_plx: fix CIS verification
The length of the manfid CIS should be at least 4, and it's normally 4.
It's incorrect to require it to be at least 5. This breaks support for
most (if not all) cards.
The right place to ensure that we don't access beyond the CIS buffer is
to strengthen another check. Make sure that the next tuple begins at
least at the CIS buffer end (in which case we stop processing) or
before that.

[PATCH] sata_sis: fix flags handling for the secondary port
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.

The sky2 driver uses a single NAPI poll routine for both ports on dual ported
cards (because there is a single IRQ and status ring). Netpoll makes assumptions
about the relationship between network device and NAPI that aren't correct
on the second port, this will cause the port to never clear work.
Most systems, just have single port, so not a big issue.
The easy fix is just make the second port, not netpoll capable.
