The dynamic ftrace ops startup test currently fails on Thumb-2 kernels:
Testing tracer function: PASSED
Testing dynamic ftrace: PASSED
Testing dynamic ftrace ops #1: (0 0 0 0 0) FAILED!
This is because while the addresses in the mcount records do not have
the zero bit set, the IP reported by the mcount call does have it set
(because it is copied from the LR). This mismatch causes the ops
filtering in ftrace_ops_list_func() to not call the relevant tracers.
Fix this by clearing the zero bit before adjusting the LR for the mcount
instruction size. Also, combine the mov+sub into a single sub
instruction.

Since commit 0536bdf33faf (ARM: move iotable mappings within
the vmalloc region), the RealView PB11MP cannot boot anymore.
This is caused by the way the mappings are described on this
platform (define replaced by hex values for clarity):
{ /* GIC CPU interface mapping */
.virtual = IO_ADDRESS(0x1F000100),
.pfn = __phys_to_pfn(0x1F000100),
.length = SZ_4K,
.type = MT_DEVICE,
}, { /* GIC distributor mapping */
.virtual = IO_ADDRESS(0x1F001000),
.pfn = __phys_to_pfn(0x1F001000),
.length = SZ_4K,
.type = MT_DEVICE,
}
The first mapping ends up reserving two pages, and clashes with
the second one, which triggers a BUG_ON in vm_area_add_early().
In order to solve this problem, treat the MPCore private memory
region (containing the SCU, the GIC and the TWD) as a single region,
as described in the TRM:
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0360f/CACGDJJC.html
The EB11MP is converted the same way, even if it manages to avoid
the problem.
Tested on both PB11MP and EB11MP.

The refactoring of Realtek codec driver in 3.2 kernel caused a
regression for ASUS A6Rp laptop; it doesn't give any output.
The reason was that this machine has a secret master mute (or EAPD)
control via NID 0x0f VREF. Setting VREF50 on this node makes the
sound working again.

Recent changes to the handling of PCI resources for host bridges
are breaking the PowerNV code for assigning resources on IODA.
The root of the problem is that the pci_bus attached to a host
bridge no longer has its "legacy" resource pointers populated
but only uses the newer list instead.

The synchronize_rcu() call resulting from making every serial driver
wake-up capable (commit b3b708fa) slows boot down on my Tegra2x system
(with CONFIG_PREEMPT disabled).
But this is avoidable since it is the device_set_wakeup_enable() and then
subsequence disable which causes the delay. We might as well just make
the device wakeup capable but not actually enable it for wakeup until
needed.
Effectively the current code does this:
device_set_wakeup_capable(dev, 1);
device_set_wakeup_enable(dev, 1);
device_set_wakeup_enable(dev, 0);
We can just drop the last two lines.
Before this change my boot log says:
[ 0.227062] Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled
[ 0.702928] serial8250.0: ttyS0 at MMIO 0x70006040 (irq = 69) is a Tegra

Protect against pl011_console_write() and the interrupt for
the console UART running concurrently on different CPUs.
Otherwise the console_write could spin for a long time
waiting for the UART to become not busy, while the other
CPU continuously services UART interrupts and keeps the
UART busy.
The checks for sysrq and oops_in_progress are taken
from 8250.c.

In present driver, shutdown clears RTS and DTR in CR register. But the
documentation "Documentation/serial/driver" suggests not to disable
RTS and DTR in shutdown(). Also RTS and DTR is preserved between shutdown
and startup calls, i.e. these are restored in startup if they were enabled
while doing shutdown. So that if RTS and DTR are set using pl011_set_mctrl
then it should continue even after shutdown->startup sequence.
For throttling/unthrottling user should call pl011_set_mctrl.

The probe does not strictly require the USB_CDC_DMM_TYPE
descriptor, which is a good thing as it makes the driver
usable on non-conforming interfaces. A user could e.g.
bind to it to a CDC ECM interface by using the new_id and
bind sysfs files. But this would fail with a 0 buffer length
due to the missing descriptor.

It seems that when the transmit FIFO threshold is reached on OMAP
UARTs, it does not result in a PRCM wakeup. This appears to be a
silicon bug. This means that if the MPU powerdomain is in a low-power
state, the MPU will not be awakened to refill the FIFO until the next
interrupt from another device.
The best solution, at least for the short term, would be for the OMAP
serial driver to call a OMAP subarchitecture function to prevent the
MPU powerdomain from entering a low power state while the FIFO has
data to transmit. However, we no longer have a clean way to do this,
since patches that add platform_data function pointers have been
deprecated by the OMAP maintainer. So we attempt to work around this
as well. The workarounds depend on the setting of CONFIG_CPU_IDLE.
When CONFIG_CPU_IDLE=n, the driver will now only transmit one byte at
a time. This causes the transmit FIFO threshold interrupt to stay
active until there is no more data to be sent. Thus, the MPU
powerdomain stays on during transmits. Aside from that energy
consumption penalty, each transmitted byte results in a huge number of
UART interrupts -- about five per byte. This wastes CPU time and is
quite inefficient, but is probably the most expedient workaround in
this case.
When CONFIG_CPU_IDLE=y, there is a slightly more direct workaround:
the PM QoS constraint can be abused to keep the MPU powerdomain on.
This results in a normal number of interrupts, but, similar to the
above workaround, wastes power by preventing the MPU from entering
WFI.
Future patches are planned for the 3.4 merge window to implement more
efficient, but also more disruptive, workarounds to these problems.
DMA operation is unaffected by this patch.

Ensure FIFO levels are set correctly in non-DMA mode (the default).
This patch will cause a receive FIFO threshold interrupt to be raised when
there is at least one byte in the RX FIFO. It will also cause a transmit
FIFO threshold interrupt when there is only one byte remaining in the TX
FIFO.
These changes fix the receive interrupt problem and part of the
transmit interrupt problem. A separate set of issues must be worked
around for the transmit path to have a basic level of functionality; a
subsequent patch will address these.
DMA operation is unaffected by this patch.

rds_sock_info() triggers locking warnings because we try to perform a
local_bh_enable() (via sock_i_ino()) while hardware interrupts are
disabled (via taking rds_sock_lock).
There is no reason for rds_sock_lock to be a hardware IRQ disabling
lock, none of these access paths run in hardware interrupt context.
Therefore making it a BH disabling lock is safe and sufficient to
fix this bug.

Commit 74c2107759d (serial: Use block_til_ready helper) and its fixup
3f582b8c110 (serial: fix termios settings in open) introduced a
regression on UV systems. The serial eventually freezes while being
used. It's completely unpredictable and sometimes needs a heap of
traffic to happen first.
To reproduce this, yast installation was used as it turned out to be
pretty reliable in reproducing. Especially during installation process
where one doesn't have an SSH daemon running. And no monitor as the HW
is completely headless. So this was fun to find. Given the machine
doesn't boot on vanilla before 2.6.36 final. (And the commits above
are older.)
Unless there is some bad race in the code, the hardware seems to be
pretty broken. Otherwise pure MSR read should not cause such a bug,
or?
So to prevent the bug, revert to the old behavior. I.e. read modem
status only if we really have to -- for non-CLOCAL set serials.
Non-CLOCAL works on this hardware OK, I tried. See? I don't.
And document that shit.

An implicit instance of module.h leaked back into existence
and was masking the fact that these drivers weren't calling
out the include for itself. Fix the drivers before we remove
the implicit include path via net/netprio_cgroup.h file.

There is a race on sk_receive_queue between llc_ui_recvmsg and
sock_queue_rcv_skb.
Our current solution is to protect skb_eat in llc_ui_recvmsg
with the queue spinlock.

After commit "db8857b stmmac: use an unique MDIO bus name" my
device stopped being probed because two different names were being
used in different places. This fixes the inconsistency.

This patch (as1515) fixes some unavoidably dumb compiler warnings:
CC [M] drivers/usb/renesas_usbhs/mod.o
In file included from drivers/usb/host/ohci-hcd.c:101:0:
drivers/usb/host/ohci-dbg.c: In function ‘fill_registers_buffer’:
drivers/usb/host/ohci-dbg.c:656:2: warning: the comparison will always evaluate as ‘true’ for the address of ‘next’ will never be NULL [-Waddress]
drivers/usb/host/ohci-dbg.c:675:3: warning: the comparison will always evaluate as ‘true’ for the address of ‘next’ will never be NULL [-Waddress]
Instead of trying to fix the macro to work under all cirumstances,
just add a second macro for use in cases where the "next" argument is
the address of a local variable.
Unfortunately the macro cannot be replaced by a real subroutine,
because there's no va_list version of ohci_dbg() or dev_dbg().
