time: Compensate for rounding on odd-frequency clocksources
commit
a386b5af8edda1c742ce9f77891e112eefffc005 upstream.
When the clocksource is not a multiple of HZ, the clock will be off. For
acpi_pm, HZ=1000 the error is 127.111 ppm:
The rounding of cycle_interval ends up generating a false error term in
ntp_error accumulation since xtime_interval is not exactly 1/HZ. So, we
subtract out the error caused by the rounding.
This has been visible since 2.6.32-rc2
commit
a092ff0f90cae22b2ac8028ecd2c6f6c1a9e4601
time: Implement logarithmic time accumulation
That commit raised NTP_INTERVAL_FREQ and exposed the rounding error.

xen: events: do not unmask event channels on resume
commit
6903591f314b8947d0e362bda7715e90eb9df75e upstream.
The IRQ core code will take care of disabling and reenabling
interrupts over suspend resume automatically, therefore we do not need
to do this in the Xen event channel code.
The only exception is those event channels marked IRQF_NO_SUSPEND
which the IRQ core ignores. We must unmask these ourselves, taking
care to obey the current IRQ_DISABLED status. Failure check for
IRQ_DISABLED leads to enabling polled only event channels, such as
that associated with the pv spinlocks, which must never be enabled:

commit
4319cc0cf5bb894b7368008cdf6dd20eb8868018 upstream.
The IPv6 header is not zeroed out in alloc_skb so we must initialize
it properly unless we want to see IPv6 packets with random TOS fields
floating around. The current implementation resets the flow label
but this could be changed if deemed necessary.
We stumbled upon this issue when trying to apply a mangle rule to
the RST packet generated by the REJECT target module.

exec: delay address limit change until point of no return
commit
dac853ae89043f1b7752875300faf614de43c74b upstream.
Unconditionally changing the address limit to USER_DS and not restoring
it to its old value in the error path is wrong because it prevents us
using kernel memory on repeated calls to this function. This, in fact,
breaks the fallback of hard coded paths to the init program from being
ever successful if the first candidate fails to load.
With this patch applied switching to USER_DS is delayed until the point
of no return is reached which makes it possible to have a multi-arch
rootfs with one arch specific init binary for each of the (hard coded)
probed paths.
Since the address limit is already set to USER_DS when start_thread()
will be invoked, this redundancy can be safely removed.

xfs: properly account for reclaimed inodes
commit
081003fff467ea0e727f66d5d435b4f473a789b3 upstream.
When marking an inode reclaimable, a per-AG counter is increased, the
inode is tagged reclaimable in its per-AG tree, and, when this is the
first reclaimable inode in the AG, the AG entry in the per-mount tree
is also tagged.
When an inode is finally reclaimed, however, it is only deleted from
the per-AG tree. Neither the counter is decreased, nor is the parent
tree's AG entry untagged properly.
Since the tags in the per-mount tree are not cleared, the inode
shrinker iterates over all AGs that have had reclaimable inodes at one
point in time.
The counters on the other hand signal an increasing amount of slab
objects to reclaim. Since "
70e60ce xfs: convert inode shrinker to
per-filesystem context" this is not a real issue anymore because the
shrinker bails out after one iteration.
But the problem was observable on a machine running v2.6.34, where the
reclaimable work increased and each process going into direct reclaim
eventually got stuck on the xfs inode shrinking path, trying to scan
several million objects.
Fix this by properly unwinding the reclaimable-state tracking of an
inode when it is reclaimed.

ACPI: use _HID when supplied by root-level devices
commit
b7b30de53aef6ce773d34837ba7d8422bd3baeec upstream.
Previously, we assumed the only Device object immediately below the root
was the \_SB Scope (which the ACPI CA treats as a Device), so we forced
the HID of all such objects to ACPI_BUS_HID ("LNXSYBUS").
However, there are DSDTs that supply root-level Device objects with _HIDs.
This patch makes us pay attention to those _HIDs and only add the synthetic
ACPI_BUS_HID for root-level objects that do not supply their own _HID.
For example, this DSDT: https://bugzilla.kernel.org/show_bug.cgi?id=15605
contains:
Scope (_SB) {
...
}
Device (AMW0) {
Name (_HID, EisaId ("PNP0C14"))
...
}
and we should use "PNP0C14" for the AMW0 device, not "LNXSYBUS".

pata_cm64x: fix boot crash on parisc
commit
9281b16caac1276817b77033c5b8a1f5ca30102c upstream.
The old IDE cmd64x checks the status of the CNTRL register to see if
the ports are enabled before probing them. pata_cmd64x doesn't do
this, which causes a HPMC on parisc when it tries to poke at the
secondary port because apparently the BAR isn't wired up (and a
non-responding piece of memory causes a HPMC).
Fix this by porting the CNTRL register port detection logic from IDE
cmd64x. In addition, following converns from Alan Cox, add a check to
see if a mobility electronics bridge is the immediate parent and forgo
the check if it is (prevents problems on hotplug controllers).

USB: xhci - fix interval calculation for FS isoc endpoints
commit
cd3c18ba2fac14b34d03cae111f215009735ea06 upstream.
Full-speed isoc endpoints specify interval in exponent based form in
frames, not microframes, so we need to adjust accordingly.
NEC xHCI host controllers will return an error code of 0x11 if a full
speed isochronous endpoint is added with the Interval field set to
something less than 3 (2^3 = 8 microframes, or one frame). It is
impossible for a full speed device to have an interval smaller than one
frame.
This was always an issue in the xHCI driver, but commit
dfa49c4ad120a784ef1ff0717168aa79f55a483a "USB: xhci - fix math in
xhci_get_endpoint_interval()" removed the clamping of the minimum value
in the Interval field, which revealed this bug.
This needs to be backported to stable kernels back to 2.6.31.

drm/radeon/kms: fix for radeon on systems >4GB without hardware iommu
commit
62fff811d73095bd95579d72f558f03c78f7914a upstream.
On my x86_64 system with >4GB of ram and swiotlb instead of
a hardware iommu (because I have a VIA chipset), the call
to pci_set_dma_mask (see below) with 40bits returns an error.
But it seems that the radeon driver is designed to have
need_dma32 = true exactly if pci_set_dma_mask is called
with 32 bits and false if it is called with 40 bits.
I have read somewhere that the default are 32 bits. So if the
call fails I suppose that need_dma32 should be set to true.
And indeed the patch fixes the problem I have had before
and which I had described here:

drm/i915: Add a no lvds quirk for the Asus EeeBox PC EB1007
commit

I found this while figuring out why gnome-shell would not run on my
Asus EeeBox PC EB1007. As a standalone "pc" this device cleary does not have
an internal panel, yet it claims it does. Add a quirk to fix this.

lockdep: Fix lock_is_held() on recursion
commit
f2513cde93f0957d5dc6c09bc24b0cccd27d8e1d upstream.
The main lock_is_held() user is lockdep_assert_held(), avoid false
assertions in lockdep_off() sections by unconditionally reporting the
lock is taken.
[ the reason this is important is a lockdep_assert_held() in ttwu()
which triggers a warning under lockdep_off() as in printk() which
can trigger another wakeup and lock up due to spinlock
recursion, as reported and heroically debugged by Arne Jansen ]

nl80211: fix check for valid SSID size in scan operations
commit
208c72f4fe44fe09577e7975ba0e7fa0278f3d03 upstream.
In both trigger_scan and sched_scan operations, we were checking for
the SSID length before assigning the value correctly. Since the
memory was just kzalloc'ed, the check was always failing and SSID with
over 32 characters were allowed to go through.
This was causing a buffer overflow when copying the actual SSID to the
proper place.
This bug has been there since 2.6.29-rc4.

PCI: Set PCIE maxpayload for card during hotplug insertion
commit
e522a7126c7c144a1dd14c6f217ac31e71082b1d upstream.
The following patch sets the MaxPayload setting to match the parent
reading when inserting a PCIE card into a hotplug slot. On our system,
the upstream bridge is set to 256, but when inserting a card, the card
setting defaults to 128. As soon as I/O is performed to the card it
starts receiving errors since the payload size is too small.
