Pull yet more SPDX updates from Greg KH:
"Here is another set of reviewed patches that adds SPDX tags to
different kernel files, based on a set of rules that are being used to
parse the comments to try to determine that the license of the file is
"GPL-2.0-or-later" or "GPL-2.0-only". Only the "obvious" versions of
these matches are included here, a number of "non-obvious" variants of
text have been found but those have been postponed for later review
and analysis.
There is also a patch in here to add the proper SPDX header to a bunch
of Kbuild files that we have missed in the past due to new files being
added and forgetting that Kbuild uses two different file names for
Makefiles. This issue was reported by the Kbuild maintainer.
These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on
the patches are reviewers"

The existing floating point emulations is only available for floating
instruction that possibly issue denormalized input and underflow
exceptions. These existing FPU emulations are not sufficient when IEx
Trap is enabled because some floating point instructions only issue inexact
exception. This patch adds the emulations of such floating point
instructions.

In order for kernel to capture each denormalized output, the UDF
trapping enable bit is always raised in $fpcsr. Because underflow case will
issue not an underflow exception but also an inexact exception, it causes
that the IEX, IEX cumulative exception, flag in $fpcsr to be raised in each
denormalized output handling. To make the emulation transparent to the
user, the emulator needs to clear the IEX flag in $fpcsr if the result is a
denormalized number. However, if the IEX flag has been raised before this
floating point emulation, this cleanup may be incorrect. To avoid the IEX
flags in $fpcsr be raised in each denormalized output handling, the IEX
trap shall be always enabled.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"The fixes are still trickling in for arm64, but the only really
significant one here is actually fixing a regression in the botched
module relocation range checking merged for -rc2.
Hopefully we've nailed it this time.
- Fix implementation of our set_personality() system call, which
wasn't being wrapped properly
- Fix system call function types to keep CFI happy
- Fix siginfo layout when delivering SIGKILL after a kernel fault
- Really fix module relocation range checking"
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: use the correct function type for __arm64_sys_ni_syscall
arm64: use the correct function type in SYSCALL_DEFINE0
arm64: fix syscall_fn_t type
signal/arm64: Use force_sig not force_sig_fault for SIGKILL
arm64/module: revert to unsigned interpretation of ABS16/32 relocations
arm64: Fix the arm64_personality() syscall wrapper redirection

Since commit 9012d011660ea5cf2 ("compiler: allow all arches to enable
CONFIG_OPTIMIZE_INLINING"), xtensa:tinyconfig fails to build with section
mismatch errors.
WARNING: vmlinux.o(.text.unlikely+0x68): Section mismatch in reference
from the function ___pa()
to the function .meminit.text:memblock_reserve()
WARNING: vmlinux.o(.text.unlikely+0x74): Section mismatch in reference
from the function mem_reserve()

FATAL: modpost: Section mismatches detected.
This was not seen prior to the above mentioned commit because mem_reserve()
was always inlined.
Mark mem_reserve(() as __init_memblock to have it reside in the same
section as memblock_reserve().

Commit 9ed0985332a6 ("x86: intel_epb: Take CONFIG_PM into account")
prevented the majority of the Performance and Energy Bias Hint (EPB)
handling code from being built when CONFIG_PM is unset to fix a
regression introduced by commit b9c273babce7 ("PM / arch: x86:
MSR_IA32_ENERGY_PERF_BIAS sysfs interface").
In hindsight, however, it would be better to skip all of the EPB
handling code for CONFIG_PM unset as there really is no reason for
it to be there in that case. Namely, if the EPB is not touched
by the kernel at all with CONFIG_PM unset, there is no need to
worry about modifying the EPB inadvertently on CPU online and since
the system will not suspend or hibernate then, there is no need to
worry about possible modifications of the EPB by the platform
firmware during system-wide PM transitions.
For this reason, revert the changes made by commit 9ed0985332a6
and only allow intel_epb.o to be built when CONFIG_PM is set.
Note that this changes the behavior of the kernels built with
CONFIG_PM unset as they will not modify the EPB on boot if it is
zero initially any more, so it is not a fix strictly speaking, but
users building their kernels with CONFIG_PM unset really should not
expect them to take energy efficiency into account. Moreover, if
CONFIG_PM is unset for performance reasons, leaving EPB as set
initially by the platform firmware will actually be consistent
with the user's expectations.

The sprgs are a set of 4 general purpose sprs provided for software use.
SPRG3 is special in that it can also be read from userspace. Thus it is
used on linux to store the cpu and numa id of the process to speed up
syscall access to this information.
This register is overwritten with the guest value on kvm guest entry,
and so needs to be restored on exit again. Thus restore the value on
the guest exit path in kvmhv_p9_guest_entry().

Commit 3309bec85e60 ("KVM: PPC: Book3S HV: Fix lockdep warning when
entering the guest") moved calls to trace_hardirqs_{on,off} in the
entry path used for HPT guests. Similar code exists in the new
streamlined entry path used for radix guests on POWER9. This makes
the same change there, so as to avoid lockdep warnings such as this:

Under XIVE, the ESB pages of an interrupt are used for interrupt
management (EOI) and triggering. They are made available to guests
through a mapping of the XIVE KVM device.
When a device is passed-through, the passthru_irq helpers,
kvmppc_xive_set_mapped() and kvmppc_xive_clr_mapped(), clear the ESB
pages of the guest IRQ number being mapped and let the VM fault
handler repopulate with the correct page.
The ESB pages are mapped at offset 4 (KVM_XIVE_ESB_PAGE_OFFSET) in the
KVM device mapping. Unfortunately, this offset was not taken into
account when clearing the pages. This lead to issues with the
passthrough devices for which the interrupts were not functional under
some guest configuration (tg3 and single CPU) or in any configuration
(e1000e adapter).

According to Documentation/virtual/kvm/locking.txt, the srcu read lock
should be taken when accessing the memslots of the VM. The XIVE KVM
device needs to do so when configuring the page of the OS event queue
of vCPU for a given priority and when marking the same page dirty
before migration.
This avoids warnings such as :

The passthrough interrupts are defined at the host level and their IRQ
data should not be cleared unless specifically deconfigured (shutdown)
by the host. They differ from the IPI interrupts which are allocated
by the XIVE KVM device and reserved to the guest usage only.
This fixes a host crash when destroying a VM in which a PCI adapter
was passed-through. In this case, the interrupt is cleared and freed
by the KVM device and then shutdown by vfio at the host level.

The XICS-on-XIVE KVM device needs to allocate XIVE event queues when a
priority is used by the OS. This is referred as EQ provisioning and it
is done under the hood when :
1. a CPU is hot-plugged in the VM
2. the "set-xive" is called at VM startup
3. sources are restored at VM restore
The kvm->lock mutex is used to protect the different XIVE structures
being modified but in some contexts, kvm->lock is taken under the
vcpu->mutex which is not permitted by the KVM locking rules.
Introduce a new mutex 'lock' for the KVM devices for them to
synchronize accesses to the XIVE device structures.

The pistachio platform uses the U-Boot bootloader & generally boots a
kernel in the uImage format. As such it's useful to build one when
building the kernel, but to do so currently requires the user to
manually specify a uImage target on the make command line.
Make uImage.gz the pistachio platform's default build target, so that
the default is to build a kernel image that we can actually boot on a
board such as the MIPS Creator Ci40.
Marked for stable backport as far as v4.1 where pistachio support was
introduced. This is primarily useful for CI systems such as kernelci.org
which will benefit from us building a suitable image which can then be
booted as part of automated testing, extending our test coverage to the
affected stable branches.
