9eeb08986f Add support for allocating irqs for bootbus devices
Some devices that can generate interrupts are connected directly to the
CPU through the bootbus on sun4d. This patch allows IRQs to be allocated
for such devices. The information used for allocating interrupts for
sbus devices are present at the corresponding SBI node. For bootbus
devices this information is present in the bootbus node.

ea16058457 Do not skip interrupt sources in sun4d interrupt handler and acknowledge interrupts correctly
During the introduction of genirq on sparc32 bugs were introduced in
the interrupt handler for sun4d. The interrupts handler checks the status
of the various sbus interfaces in the system and generates a virtual
interrupt, based upon the location of the interrupt source. This lookup
was broken by restructuring the code in such a way that index and shift
operations were performed prior to comparing this against the values
read from the interrupt controllers.

This could cause the handler to loop eternally as the interrupt source
could be skipped before any check was performed. Additionally
sun4d_encode_irq performs shifting internally, so it should not be performed
twice.

In sun4d_unmask interrupts were not correctly acknowledged, as the
corresponding bit it the interrupt mask was not actually cleared.

5fba17084e Restructure sun4d_build_device_irq so that timer interrupts can be allocated
sun4d_build_device_irq was called without a valid platform_device when
the system timer was initialized on sun4d systems. This caused a NULL
pointer crash.

Josip Rodin suggested that the current sun4d_build_device_irq should be
split into two functions. So that the timer initialization could skip
the slot and sbus interface detection code in sun4d_build_device_irq, as
this does not make sence due to the timer interrupts not being generated
from a device located on sbus.

470f229754 ARM: SAMSUNG: serial: Fix on handling of one clock source for UART
This patch fixes the way of comparison for handling of two or more
clock sources for UART.

For example, if just only one clock source is defined even though
there are two clock sources for UART, the serial driver does not
set proper clock up. Of course, it is problem.

So this patch changes the condition of comparison to avoid useless
setup clock and adds a flag 'NO_NEED_CHECK_CLKSRC' which means
selection of source clock is not required.

In addition, since the Exynos4210 has only one clock source for UART
this patch adds the flag into its common_init_uarts().

26018874e3 x86/amd-iommu: Fix boot crash with hidden PCI devices
Some PCIe cards ship with a PCI-PCIe bridge which is not
visible as a PCI device in Linux. But the device-id of the
bridge is present in the IOMMU tables which causes a boot
crash in the IOMMU driver.
This patch fixes by removing these cards from the IOMMU
handling. This is a pure -stable fix, a real fix to handle
this situation appriatly will follow for the next merge
window.

After commit 4d27e9dcff00a6425d779b065ec8892e4f391661 (PM: Make power
domain callbacks take precedence over subsystem ones), the power
domain callbacks need to call the driver callbacks instead of relying
on the default subsystem (in this case, platform_bus) to handle the
driver callbacks.

a578b37cc2 [S390] kvm-s390: Fix host crash on misbehaving guests
commit 9ff4cfb3fcfd48b49fdd9be7381b3be340853aa4 ([S390] kvm-390: Let
kernel exit SIE instruction on work) fixed a problem of commit
commit cd3b70f5d4d82f85d1e1d6e822f38ae098cf7c72 ([S390] virtualization
aware cpu measurement) but uncovered another one.

If a kvm guest accesses guest real memory that doesnt exist, the
page fault handler calls the sie hook, which then rewrites
the return psw from sie_inst to either sie_exit or sie_reenter.
On return, the page fault handler will then detect the wrong access
as a kernel fault causing a kernel oops in sie_reenter or sie_exit.

We have to add these two addresses to the exception  table to allow
graceful exits.

9fc2552a68 ARM: 6952/1: fix lockdep warning of "unannotated irqs-off"
This patch fixes the lockdep warning of "unannotated irqs-off"[1].

After entering __irq_usr, arm core will disable interrupt automatically,
but __irq_usr does not annotate the irq disable, so lockdep may complain
the warning if it has chance to check this in irq handler.

This patch adds trace_hardirqs_off in __irq_usr before entering irq_handler
to handle the irq, also calls ret_to_user_from_irq to avoid calling
disable_irq again.

This is also a fix for irq off tracer.

363e9f05cb sh: Remove compressed kernel libgcc dependency.
SH-2A is unable to combine the kernel and libgcc objects due to
fundamental disagreements over FDPIC settings. As the kernel already
contains all of the libgcc bits broken out, there's not much need to
bother with the linking anymore, as everything can already be derived
from the lib dir.

This simply plugs in the necessary bits to ensure that everything is
built uniformly, enabling us to wean the compressed build off of explicit
libgcc linking.

Commit f6511935f42 moved the permission check for io instructions
to the ->check_perm callback. It failed to copy the port value from RDX
register for string and "in,out ax,dx" instructions.

Fix it by reading RDX register at decode stage when appropriate.

Fixes FC8.32 installation.

298c48a811 sh: fix wrong icache/dcache address-array start addr in cache-debugfs.
This patch fixes a icache/dcache address-array start address while
dumping its entires in debugfs. Perviously the code was attempting to
remember the address in static variable, which is no more required
for debugfs, as the function can be executed in one pass.

Without this patch the start address ends up in wrong place and the
/sys/kernel/debug/sh/icache or dcache debugfs contents may not be correct.

f2a4d8ae4d ARM: Tegra: Harmony: Fix conflicting GPIO numbering
Currently, both the WM8903 and TPS6586x chips attempt to register with
gpiolib using the same GPIO numbers. This causes the audio driver to
fail to initialize.

To solve this, add a define to board-harmony.h for the TPS6586x, and make
board-harmony-power.c use this define, instead of directly referencing
TEGRA_NR_GPIOS.

This fixes a regression introduced by commit
6f168f2fa60f87e85e0df25e87e2372f22f5eb7c.

5d07b7869a sparc32,leon: add GRPCI2 PCI Host driver
The DMA region must be accessible in order for PCI peripheral
drivers to work, the sparc32 has DMA in the normal memory
zone which requires the GRPCI2 to PCI target BARs so that all
kernel low mem (192MB) can be mapped 1:1 to PCI address
space. The GRPCI2 has resizeable target BARs, by default the
first is made 256MB and all other BARs are disabled.

I/O space are always located on 0x1000-0x10000, but accessed
through the GRPCI2 PCI I/O Window memory mapped to virtual
address space.

Configuration space is accessed through the 64KB GRPCI2 PCI
CFG Window using LDA bypassing the MMU.

The GRPCI2 has a single PCI Window for prefetchable and non-
prefetchable address space, it is up to the AHB master
requesting PCI data to determine access type. Memory space
is mapped 1:1.

The GRPCI2 core can be configured in 4 different IRQ modes,
where PCI Interrupt, Error Interrupt and DMA Interrupt are
shared on a single IRQ line or at most 5 IRQs are used. The
GRPCI2 can mask/unmask PCI interrupts, Err and DMA in the control
and check status bits which tells us which IRQ really happended.
The GENIRQ layer is used to unmask/mask each individual IRQ
source by creating virtual IRQs and implementing a IRQ chip.

The optional DMA functionality of the GRPCI2 is not supported
by this patch.
