Lucas Stach 9cf82e72ec irqchip: tegra: Set the proper base address in irq chip data
The irq chip functions use the irq chipdata directly as the base register
address of the controller, so this should be passed in instead of a pointer
to the array address holding the base address.

This fixes Tegra20 CPUidle as now the un-/masking of IRQs at the LIC level
works again, but more importantly it fixes the resulting memory corruption.

Krzysztof Kozlowski 0b7dc0ff95 ARM: EXYNOS: Fix dereference of ERR_PTR returned by of_genpd_get_from_provider
ERR_PTR was dereferenced during sub domain parsing, if parent domain
could not be obtained (because of invalid phandle or deferred
registration of parent domain).

The Exynos power domain code checked whether
of_genpd_get_from_provider() returned NULL and in that case it skipped
that power domain node. However this function returns ERR_PTR or valid
pointer, not NULL.

Niklas Cassel bced870152 net: phy: micrel: Fix regression in kszphy_probe
Don't do clock-mode-select if clk == NULL,
since when building without CONFIG_HAVE_CLK,
clk_get returns NULL and clk_get_rate returns 0.

Doing clock-mode-select in this cause causes kszphy_probe to
return -EINVAL and thus prevents the device from being probed.

The original code (before regression) would return 0
when building without CONFIG_HAVE_CLK.

Maciej W. Rozycki 03dce59527 MIPS: Fix a preemption issue with thread's FPU defaults
Fix "BUG: using smp_processor_id() in preemptible" reported in accesses
to thread's FPU defaults: the value to initialise FSCR to at program
startup, the FCSR r/w mask and the contents of FIR in full FPU
emulation, removing a regression introduced with 9b26616c [MIPS: Respect
the ISA level in FCSR handling] and f6843626 [MIPS: math-emu: Set FIR
feature flags for full emulation].

Use `boot_cpu_data' to obtain the data from, following the approach that
`cpu_has_*' macros take and avoiding the call to `smp_processor_id' made
in the reference to `current_cpu_data'.  The contents of FSCR have to be
consistent across processors in an SMP system, the settings there must
not change as a thread is migrated across processors.  And the contents
of FIR are guaranteed to be consistent in FPU emulation, by definition.

Helge Deller d045c77c1a parisc,metag: Fix crashes due to stack randomization on stack-grows-upwards architectures
On architectures where the stack grows upwards (CONFIG_STACK_GROWSUP=y,
currently parisc and metag only) stack randomization sometimes leads to crashes
when the stack ulimit is set to lower values than STACK_RND_MASK (which is 8 MB
by default if not defined in arch-specific headers).

The problem is, that when the stack vm_area_struct is set up in fs/exec.c, the
additional space needed for the stack randomization (as defined by the value of
STACK_RND_MASK) was not taken into account yet and as such, when the stack
randomization code added a random offset to the stack start, the stack
effectively got smaller than what the user defined via rlimit_max(RLIMIT_STACK)
which then sometimes leads to out-of-stack situations and crashes.

This patch fixes it by adding the maximum possible amount of memory (based on
STACK_RND_MASK) which theoretically could be added by the stack randomization
code to the initial stack size. That way, the user-defined stack size is always
guaranteed to be at minimum what is defined via rlimit_max(RLIMIT_STACK).

This bug is currently not visible on the metag architecture, because on metag
STACK_RND_MASK is defined to 0 which effectively disables stack randomization.

The changes to fs/exec.c are inside an "#ifdef CONFIG_STACK_GROWSUP"
section, so it does not affect other platformws beside those where the
stack grows upwards (parisc and metag).

At present we are incorrectly setting the register to 0x1 to power up
the ADC. Since it is an active high power down register, we need to set

Ville Syrjälä 4d53dc0c02 drm/edid: Add CEA modes before inferred modes
Currently we're adding CEA modes after the inferred modes, which means
we might get multiple modes that are very close to each other, but
slightly different, which seems a bit silly. That's because duplicate
mode check that occurs when adding inferred modes would not consider
CEA modes as potential duplicates. Reverse the order so that CEA
modes get added before inferred modes, and are thus considered potential
duplicates.

Or as ajax put it on irc:
"< ajax> the point of the "pick a timing formula" heuristic was to
generate something the sink could _likely_ sink.  if it tells us
timings it can sink explicitly then second-guessing seems dumb."

Paul Burton 620b155034 MIPS: fix FP mode selection in lieu of .MIPS.abiflags data
Commit 46490b5725 ("MIPS: kernel: elf: Improve the overall ABI and FPU
mode checks") reworked the ELF FP ABI mode selection logic, but when
CONFIG_MIPS_O32_FP64_SUPPORT is enabled it breaks the use of binaries
which have no PT_MIPS_ABIFLAGS program header & associated
.MIPS.abiflags section.

A default mode is selected based upon whether the ELF contains MIPS32 or
MIPS64 code, but that selection is made in arch_elf_pt_proc.
arch_elf_pt_proc only executes when a PT_MIPS_ABIFLAGS program header is
found. If one is not found then arch_elf_pt_proc is never called, and no
default overall_fp_mode value is selected. When arch_check_elf is
called, both abi0 & abi1 are MIPS_ABI_FP_UNKNOWN which leads to both
prog_req & interp_req being set to none_req. none_req matches none of
the conditions for mode selection at the end of arch_check_elf, so
overall_fp_mode is left untouched. Finally once mips_set_personality_fp
is called the BUG() in the default case is then hit & the kernel likely
panics.

Fix this by moving the selection of a default overall mode to the start
of arch_check_elf, which runs once per ELF executed regardless of
whether it has a PT_MIPS_ABIFLAGS program header.

Robert Schwebel 613880a121 ARM: vexpress/ca9: Add interrupt-affinity to the PMU node
Commit 9fd85eb502 ("ARM: pmu: add support for interrupt-affinity
property") added an optional "interrupt-affinity" property, to specify
the CPU affinity for each SPI listed in the interrupts property.

Without this property, we get this boot warning:

  CPU PMU: Failed to parse <no-node>/interrupt-affinity[0]

This patch adds interrupt-affinity to the PMU node in the
vexpress-v2p-ca9 device tree.

Commit d9d1f3e2d7 ("ARM: l2c: check that DT files specify the required
"cache-unified" property") mandates to specify this required property.
Without this property, we get this boot warning:

"L2C: device tree omits to specify unified cache"

This patch adds "cache-unified" property to L2 cache node in vexpress
CA9 device tree.
