When making the pin control submenu globally visible, all kinds
of oddities appear, in blackfin a few files were #including
<linux/gpio.h> and relying on that to pull in <asm/gpio.h>.
This was not working when pin control but not GPIOLIB was
selected resulting in a breakage in allmodconfig. The code these
files were using was still there and defined in <asm/gpio.h>
just not pulle in from just including <linux/gpio.h>
Simply add the required includes explicitly in the blackfin
kernel core and everything compiles fine.
Delete the use of the incorrect <linux/gpio.h> where possible.
Add stubs to <asm/gpio.h> for the functions called from PM:
these should probably also depend on !PINCTRL but since the
global CONFIG_PM symbol is used to compile PM support,
we need some more intrusive thing here, to be tested by
Blackfin maintainers.

The build robot is complaining on Blackfin:
drivers/pinctrl/pinctrl-adi2.c: In function 'port_setup':
>> drivers/pinctrl/pinctrl-adi2.c:221:21: error: dereferencing
pointer to incomplete type 'struct gpio_port_t'
writew(readw(®s->port_fer) & ~BIT(offset),
^~
drivers/pinctrl/pinctrl-adi2.c: In function 'adi_gpio_ack_irq':
>> drivers/pinctrl/pinctrl-adi2.c:266:18: error: dereferencing
pointer to incomplete type 'struct bfin_pint_regs'
if (readl(®s->invert_set) & pintbit)
^~
It seems the driver need to include <asm/gpio.h> and <asm/irq.h>
to compile.
The Blackfin architecture was re-defining the Kconfig
PINCTRL symbol which is not OK, so replaced this with
PINCTRL_BLACKFIN_ADI2 which selects PINCTRL and PINCTRL_ADI2
just like most arches do.
Further, the old GPIO driver symbol GPIO_ADI was possible to
select at the same time as selecting PINCTRL. This was not
working because the arch-local <asm/gpio.h> header contains
an explicit #ifndef PINCTRL clause making compilation break
if you combine them. The same is true for DEBUG_MMRS.
Make sure the ADI2 pinctrl driver is not selected at the same
time as the old GPIO implementation. (This should be converted
to use gpiolib or pincontrol and move to drivers/...) Also make
sure the old GPIO_ADI driver or DEBUG_MMRS is not selected at
the same time as the new PINCTRL implementation, and only make
PINCTRL_ADI2 selectable for the Blackfin families that actually
have it.
This way it is still possible to add e.g. I2C-based pin
control expanders on the Blackfin.

As discussed on the debian-hppa list, double-wordcompare and exchange
operations fail on 32-bit kernels. Looking at the code, I realized that
the ",ma" completer does the wrong thing in the "ldw,ma 4(%r26), %r29"
instruction. This increments %r26 and causes the following store to
write to the wrong location.

This reverts commit 94a04bc25a2c6296bd0c5e82c10e8231c2b11f77.
In order to run HPT guests on a radix POWER9 host, we will have to run
the host in single-threaded mode, because POWER9 processors do not
currently support running some threads of a core in HPT mode while
others are in radix mode ("mixed mode").
That means that we will need the same mechanisms that are used on
POWER8 to make the secondary threads available to KVM, which were
disabled on POWER9 by commit 94a04bc25a2c.

Commit 05cade71cf3b ("KVM: nSVM: fix SMI injection in guest mode") made
KVM mask SMI if GIF=0 but it didn't do anything to unmask it when GIF is
enabled.
The issue manifests for me as a significantly longer boot time of Windows
guests when running with SMM-enabled OVMF.
This commit fixes it by intercepting STGI instead of requesting immediate
exit if the reason why SMM was masked is GIF.

do_clear_cpu_cap() allocates a bitmap to keep track of disabled feature
dependencies. That bitmap is sized NCAPINTS * BITS_PER_INIT. The possible
'features' which can be handed in are larger than this, because after the
capabilities the bug 'feature' bits occupy another 32bit. Not really
obvious...
So clearing any of the misfeature bits, as 32bit does for the F00F bug,
accesses that bitmap out of bounds thereby corrupting the stack.
Size the bitmap proper and add a sanity check to catch accidental out of
bound access.

Due to timezones, commit:
b956575bed91 ("x86/mm: Flush more aggressively in lazy TLB mode")
was an outdated patch that well tested and fixed the bug but didn't
address Borislav's review comments.
Tidy it up:
- The name "tlb_use_lazy_mode()" was highly confusing. Change it to
"tlb_defer_switch_to_init_mm()", which describes what it actually
means.
- Move the static_branch crap into a helper.
- Improve comments.
Actually removing the debugfs option is in the next patch.

arch_spin_lock_flags()
arch_spin_lock_flags() is an internal part of the spinlock implementation
and is no longer available when SMP=n and DEBUG_SPINLOCK=y, so the PPC
RTAS code fails to compile in this configuration:
arch/powerpc/kernel/rtas.c: In function 'lock_rtas':

arch_spin_lock_flags(&rtas.lock, flags);
^~~~~~~~~~~~~~~~~~~~
Since there's no good reason to use arch_spin_lock_flags() here (the code
in question already calls local_irq_save(flags)), switch it over to
arch_spin_lock and get things building again.

Implement CPU alternatives, which allows to optionally patch newer
instructions at runtime, based on CPU facilities availability.
A new kernel boot parameter "noaltinstr" disables patching.
Current implementation is derived from x86 alternatives. Although
ideal instructions padding (when altinstr is longer then oldinstr)
is added at compile time, and no oldinstr nops optimization has to be
done at runtime. Also couple of compile time sanity checks are done:
1. oldinstr and altinstr must be <= 254 bytes long,
2. oldinstr and altinstr must not have an odd length.
alternative(oldinstr, altinstr, facility);
alternative_2(oldinstr, altinstr1, facility1, altinstr2, facility2);
Both compile time and runtime padding consists of either 6/4/2 bytes nop
or a jump (brcl) + 2 bytes nop filler if padding is longer then 6 bytes.
.altinstructions and .altinstr_replacement sections are part of
__init_begin : __init_end region and are freed after initialization.

Before kexec boots to a crash kernel it checks whether the image in memory
changed after load. This is done by the function kdump_csum_valid, which
returns true, i.e. an int != 0, on success and 0 otherwise. In other words
when kdump_csum_valid returns an error code it means that the validation
succeeded. This is not only counterintuitive but also produces the wrong
result if the kernel was build without CONFIG_CRASH_DUMP. Fix this by
making kdump_csum_valid return a bool.

Daniel Axtens reported that on the HiSilicon D05 board, the VGA device is
behind a bridge that doesn't support PCI_BRIDGE_CTL_VGA, so the VGA arbiter
never selects it as the default, which means Xorg auto-detection doesn't
work.
VGA is a legacy PCI feature: a VGA device can respond to addresses, e.g.,
[mem 0xa0000-0xbffff], [io 0x3b0-0x3bb], [io 0x3c0-0x3df], etc., that are
not configurable by BARs. Consequently, multiple VGA devices can conflict
with each other. The VGA arbiter avoids conflicts by ensuring that those
legacy resources are only routed to one VGA device at a time.
The arbiter identifies the "default VGA" device, i.e., a legacy VGA device
that was used by boot firmware. It selects the first device that:
- is of PCI_CLASS_DISPLAY_VGA,
- has both PCI_COMMAND_IO and PCI_COMMAND_MEMORY enabled, and
- has PCI_BRIDGE_CTL_VGA set in all upstream bridges.
Some systems don't have such a device. For example, if a host bridge
doesn't support I/O space, PCI_COMMAND_IO probably won't be enabled for any
devices below it. Or, as on the HiSilicon D05, the VGA device may be
behind a bridge that doesn't support PCI_BRIDGE_CTL_VGA, so accesses to the
legacy VGA resources will never reach the device.
This patch extends the arbiter so that if it doesn't find a device that
meets all the above criteria, it selects the first device that:
- is of PCI_CLASS_DISPLAY_VGA and
- has PCI_COMMAND_IO or PCI_COMMAND_MEMORY enabled
If it doesn't find even that, it selects the first device that:
- is of class PCI_CLASS_DISPLAY_VGA.
Such a device may not be able to use the legacy VGA resources, but most
drivers can operate the device without those. Setting it as the default
device means its "boot_vga" sysfs file will contain "1", which Xorg (via
libpciaccess) uses to help select its default output device.
This fixes Xorg auto-detection on some arm64 systems (HiSilicon D05 in
particular; see the link below).
It also replaces the powerpc fixup_vga() quirk, albeit with slightly
different semantics: the quirk selected the first VGA device we found, and
overrode that selection with any enabled VGA device we found. If there
were several enabled VGA devices, the *last* one we found would become the
default.
The code here instead selects the *first* enabled VGA device we find, and
if none are enabled, the first VGA device we find.

On some i.MX6 SoCs (like i.MX6SL, i.MX6SX and i.MX6UL) that do not have
speed grading check, opp table will not be created in platform code,
so cpufreq driver prints the following error message:
cpu cpu0: dev_pm_opp_get_opp_count: OPP table not found (-19)
However, this is not really an error in this case because the
imx6q-cpufreq driver first calls dev_pm_opp_get_opp_count()
and if it fails, it means that platform code does not provide
OPP and then dev_pm_opp_of_add_table() will be called.
In order to avoid such confusing error message, move the speed grading
check from platform code to the imx6q-cpufreq driver.
This way the imx6q-cpufreq no longer has to check whether OPP table
is supplied by platform code.

The latest dtc warns about an extraneous cell in the interrupt
property of two of the iommu device nodes:
Warning (interrupts_property): interrupts size is (16), expected multiple of 12 in /iommu@ff373f00
Warning (interrupts_property): interrupts size is (16), expected multiple of 12 in /iommu@ff900800
This removes the typo.

The vcc_sd or vcc_sdio used for IO voltage for sdmmc and sdio
interface on rk3399 platform have a limitation that it can't be
larger than 3.0v, otherwise it has a potential risk for the chip.
Correct all of them.

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

Clearing a CPU feature with setup_clear_cpu_cap() clears all features
which depend on it. Expressing feature dependencies in one place is
easier to maintain than keeping functions like
fpu__xstate_clear_all_cpu_caps() up to date.
The features which depend on XSAVE have their dependency expressed in the
dependency table, so its sufficient to clear X86_FEATURE_XSAVE.
Remove the explicit clearing of XSAVE dependent features.

Before enabling XSAVE, not only check the XSAVE specific CPUID bits,
but also the base CPUID features of the respective XSAVE feature.
This allows to disable individual XSAVE states using the existing
clearcpuid= option, which can be useful for performance testing
and debugging, and also in general avoids inconsistencies.

With a followon patch we want to make clearcpuid affect the XSAVE
configuration. But xsave is currently initialized before arguments
are parsed. Move the clearcpuid= parsing into the special
early xsave argument parsing code.
Since clearcpuid= contains a = we need to keep the old __setup
around as a dummy, otherwise it would end up as a environment
variable in init's environment.
