Two regression fixes for omaps
Two one-liners to fix board-ams-delta booting regression and
logicpd-som-lv MMC card detect to use GPIO_ACTIVE_LOW instead of
IRQ_TYPE_LEVEL_LOW. Note that the board-ams-delta regression has
been in there already since v5.0, so if necessary these can wait
for the merge window.

clock_getres in the vDSO library has to preserve the same behaviour
of posix_get_hrtimer_res().
In particular, posix_get_hrtimer_res() does:
sec = 0;
ns = hrtimer_resolution;
and hrtimer_resolution depends on the enablement of the high
resolution timers that can happen either at compile or at run time.
Fix the nds32 vdso implementation of clock_getres keeping a copy of
hrtimer_resolution in vdso data and using that directly.

Generic kernels feed many operation through the "machvec" logic to get
the correct form of the operation for the current system. "mmiowb()" is
one of those operations.
Although machvec is initialized very early in boot, it isn't early
enough for a recent upstream kernel change that added mmiowb to the
spin_unlock() path.
Statically initialize the mmiowb field of machvec so that we won't die
with a call through a NULL pointer. This should be safe because we do
the real initialization of machvec before bringing up any addtional CPUs
or doing any I/O.

The RDPMC-exiting control is dependent on the existence of the RDPMC
instruction itself, i.e. is not tied to the "Architectural Performance
Monitoring" feature. For all intents and purposes, the control exists
on all CPUs with VMX support since RDPMC also exists on all VCPUs with
VMX supported. Per Intel's SDM:
The RDPMC instruction was introduced into the IA-32 Architecture in
the Pentium Pro processor and the Pentium processor with MMX technology.
The earlier Pentium processors have performance-monitoring counters, but
they must be read with the RDMSR instruction.
Because RDPMC-exiting always exists, KVM requires the control and refuses
to load if it's not available. As a result, hiding the PMU from a guest
breaks nested virtualization if the guest attemts to use KVM.
While it's not explicitly stated in the RDPMC pseudocode, the VM-Exit
check for RDPMC-exiting follows standard fault vs. VM-Exit prioritization
for privileged instructions, e.g. occurs after the CPL/CR0.PE/CR4.PCE
checks, but before the counter referenced in ECX is checked for validity.
In other words, the original KVM behavior of injecting a #GP was correct,
and the KVM unit test needs to be adjusted accordingly, e.g. eat the #GP
when the unit test guest (L3 in this case) executes RDPMC without
RDPMC-exiting set in the unit test host (L2).
This reverts commit e51bfdb68725dc052d16241ace40ea3140f938aa.

Currently KVM sets 5 most significant bits of physical address bits
reported by CPUID (boot_cpu_data.x86_phys_bits) for nonpresent or
reserved bits SPTE to mitigate L1TF attack from guest when using shadow
MMU. However for some particular Intel CPUs the physical address bits
of internal cache is greater than physical address bits reported by
CPUID.
Use the kernel's existing boot_cpu_data.x86_cache_bits to determine the
five most significant bits. Doing so improves KVM's L1TF mitigation in
the unlikely scenario that system RAM overlaps the high order bits of
the "real" physical address space as reported by CPUID. This aligns with
the kernel's warnings regarding L1TF mitigation, e.g. in the above
scenario the kernel won't warn the user about lack of L1TF mitigation
if x86_cache_bits is greater than x86_phys_bits.
Also initialize shadow_nonpresent_or_rsvd_mask explicitly to make it
consistent with other 'shadow_{xxx}_mask', and opportunistically add a
WARN once if KVM's L1TF mitigation cannot be applied on a system that
is marked as being susceptible to L1TF.

If L1 is using an MSR bitmap, unconditionally merge the MSR bitmaps from
L0 and L1 for MSR_{KERNEL,}_{FS,GS}_BASE. KVM unconditionally exposes
MSRs L1. If KVM is also running in L1 then it's highly likely L1 is
also exposing the MSRs to L2, i.e. KVM doesn't need to intercept L2
accesses.

I also reordered a couple includes when they weren't alphabetical and
removed clk.h from kona, replacing it with clk-provider.h because
that driver doesn't use clk consumer APIs.

Pull more power management updates from Rafael Wysocki:
"These fix a recent regression causing kernels built with CONFIG_PM
unset to crash on systems that support the Performance and Energy Bias
Hint (EPB), clean up the cpufreq core and some users of transition
notifiers and introduce a new power domain flag into the generic power
domains framework (genpd).
Specifics:
- Fix recent regression causing kernels built with CONFIG_PM unset to
crash on systems that support the Performance and Energy Bias Hint
(EPB) by avoiding to compile the EPB-related code depending on
CONFIG_PM when it is unset (Rafael Wysocki).
- Clean up the transition notifier invocation code in the cpufreq
core and change some users of cpufreq transition notifiers
accordingly (Viresh Kumar).
- Change MAINTAINERS to cover the schedutil governor as part of
cpufreq (Viresh Kumar).
- Simplify cpufreq_init_policy() to avoid redundant computations (Yue
Hu).
- Add explanatory comment to the cpufreq core (Rafael Wysocki).
- Introduce a new flag, GENPD_FLAG_RPM_ALWAYS_ON, to the generic
power domains (genpd) framework along with the first user of it
(Leonard Crestez)"

Commit 60a3cdd06394 ("x86: add optimized inlining") introduced
CONFIG_OPTIMIZE_INLINING, but it has been available only for x86.
The idea is obviously arch-agnostic. This commit moves the config entry
from arch/x86/Kconfig.debug to lib/Kconfig.debug so that all
architectures can benefit from it.
This can make a huge difference in kernel image size especially when
CONFIG_OPTIMIZE_FOR_SIZE is enabled.
For example, I got 3.5% smaller arm64 kernel for v5.1-rc1.
dec file
18983424 arch/arm64/boot/Image.before
18321920 arch/arm64/boot/Image.after
This also slightly improves the "Kernel hacking" Kconfig menu as
e61aca5158a8 ("Merge branch 'kconfig-diet' from Dave Hansen') suggested;
this config option would be a good fit in the "compiler option" menu.

Patch series "compiler: allow all arches to enable
CONFIG_OPTIMIZE_INLINING", v3.
This patch (of 11):
When function tracing for IPIs is enabled, we get a warning for an
overflow of the ipi_types array with the IPI_CPU_BACKTRACE type as
triggered by raise_nmi():
arch/arm/kernel/smp.c: In function 'raise_nmi':
arch/arm/kernel/smp.c:489:2: error: array subscript is above array bounds [-Werror=array-bounds]
trace_ipi_raise(target, ipi_types[ipinr]);
This is a correct warning as we actually overflow the array here.
This patch raise_nmi() to call __smp_cross_call() instead of
smp_cross_call(), to avoid calling into ftrace. For clarification, I'm
also adding a two new code comments describing how this one is special.
The warning appears to have shown up after commit e7273ff49acf ("ARM:
8488/1: Make IPI_CPU_BACKTRACE a "non-secure" SGI"), which changed the
number assignment from '15' to '8', but as far as I can tell has existed
since the IPI tracepoints were first introduced. If we decide to
backport this patch to stable kernels, we probably need to backport
e7273ff49acf as well.
[yamada.masahiro@socionext.com: rebase on v5.1-rc1]

The "WITH Linux-syscall-note" should be added to headers exported to the
user-space.
Some kernel-space headers have "WITH Linux-syscall-note", which seems a
mistake.
[1] arch/x86/include/asm/hyperv-tlfs.h
Commit 5a4858032217 ("x86/hyper-v: move hyperv.h out of uapi") moved
this file out of uapi, but missed to update the SPDX License tag.
[2] include/asm-generic/shmparam.h
Commit 76ce2a80a28e ("Rename include/{uapi => }/asm-generic/shmparam.h
really") moved this file out of uapi, but missed to update the SPDX
License tag.
[3] include/linux/qcom-geni-se.h
Commit eddac5af0654 ("soc: qcom: Add GENI based QUP Wrapper driver")
added this file, but I do not see a good reason why its license tag must
include "WITH Linux-syscall-note".

__do_page_fault+0x77c/0x1f00
do_page_fault+0x28/0x50
handle_page_fault+0x18/0x38
This is caused by us trying to allocate from a NULL kmem cache in
__hugepte_alloc(). The kmem cache is NULL because it was never
allocated in hugetlbpage_init(), because add_huge_page_size() returned
an error.
The reason add_huge_page_size() returned an error is a simple typo, we
are calling check_and_get_huge_psize(size) when we should be passing
shift instead.
The fact that we're able to trigger this path when the kmem caches are
NULL is a separate bug, ie. we should not advertise any hugepage sizes
if we haven't setup the required caches for them.
This was only seen with 4K pages, with 64K pages we don't need to
allocate any extra kmem caches because the 16M hugepage just occupies
a single entry at the PMD level.
Fixes: 723f268f19da ("powerpc/mm: cleanup ifdef mess in add_huge_page_size()")
