ARM: dts: am437x-gp-evm: add support for parallel NAND flash
Adds pinmux and DT node for Micron (MT29F4G08AB) x8 NAND device present on
am437x-gp-evm board.
(1) As NAND Flash data lines are muxed with eMMC, Thus at a given time either
eMMC or NAND can be enabled. Selection between eMMC and NAND is controlled:
(a) By dynamically driving following GPIO pin from software
SPI2_CS0(GPIO) == 0 NAND is selected (default)
SPI2_CS0(GPIO) == 1 eMMC is selected
(b) By statically using Jumper (J89) on the board
(2) As NAND device connnected to this board has page-size=4K and oob-size=224,
So ROM code expects boot-loaders to be flashed in BCH16 ECC scheme for
NAND boot.

ARM: dts: Only build OMAP dtb if associated SoC is built
With ARCH_OMAP2PLUS being separated out into OMAP2/3/4/5 etc all the TI device
tree blobs are built no matter the combination of SoCs that are enabled. This
often causes a bunch of irrelevant .dts to be built on a multi platform kernel,
this enables the building of just the ones relevant to the SoCs that are

This also helps to avoid trivial merge conflicts when adding support

arm64: fixmap: fix missing sub-page offset for earlyprintk
Commit
d57c33c5daa4 (add generic fixmap.h) added (among other
similar things) set_fixmap_io to deal with early ioremap of devices.
More recently, commit
bf4b558eba92 (arm64: add early_ioremap support)
converted the arm64 earlyprintk to use set_fixmap_io. A side effect of
this conversion is that my virtual machines have stopped booting when
I pass "earlyprintk=uart8250-8bit,0x3f8" to the guest kernel.
Turns out that the new earlyprintk code doesn't care at all about
sub-page offsets, and just assumes that the earlyprintk device will
be page-aligned. Obviously, that doesn't play well with the above example.
Further investigation shows that set_fixmap_io uses __set_fixmap instead
of __set_fixmap_offset. A fix is to introduce a set_fixmap_offset_io that
uses the latter, and to remove the superflous call to fix_to_virt
(which only returns the value that set_fixmap_io has already given us).
With this applied, my VMs are back in business. Tested on a Cortex-A57
platform with kvmtool as platform emulation.

- A recent cpufreq core change to ensure serialization of frequency
transitions for drivers with a ->target_index() callback overlooked
the fact that some of those drivers had been doing operations
introduced by it into the core already by themselves. That
resulted in a mess in which the core and the drivers try to do the

parisc: remove _STK_LIM_MAX override
There are only a couple of architectures that override _STK_LIM_MAX to
a non-infinity value. This changes the stack allocation semantics in
subtle ways. For example, GNU make changes its stack allocation to the
hard maximum defined by _STK_LIM_MAX. As a results, threads executed
by processes running under make are allocated a stack size of
_STK_LIM_MAX rather than a sensible default value. This causes various
thread stress tests to fail when they can't muster more than about 50
threads.
The attached change implements the default behavior used by the
majority of architectures.

Revert "hwmon: (coretemp) Refine TjMax detection"
This reverts commit
9fb6c9c73b11bef65ba80a362547fd116c1e1c9d.
Tjmax on some Intel CPUs is below 85 degrees C. One known example is
L5630 with Tjmax of 71 degrees C. There are other Xeon processors with
Tjmax of 70 or 80 degrees C. Also, the Intel IA32 System Programming
document states that the temperature target is in bits 23:16 of MSR 0x1a2
(MSR_TEMPERATURE_TARGET), which is 8 bits, not 7.
So even if turbostat uses similar checks to validate Tjmax, there is no
evidence that the checks are actually required. On the contrary, the
checks are known to cause problems and therefore need to be removed.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=75071.

ACPI / processor: Fix failure of loading acpi-cpufreq driver
According commit
d640113fe (ACPI: processor: fix acpi_get_cpuid for UP
processor), BIOS may not provide _MAT or MADT tables and acpi_get_apicid()
always returns -1. For these cases, original code will pass apic_id with
vaule of -1 to acpi_map_cpuid() and it will check the acpi_id. If acpi_id
is equal to zero, ignores apic_id and return zero for CPU0.
Commit
b981513 (ACPI / scan: bail out early if failed to parse APIC
ID for CPU) changed the behavior. Return ENODEV when find apic_id is
less than zero after calling acpi_get_apicid(). This causes acpi-cpufreq
driver fails to be loaded on some machines. This patch is to fix it.
