X86_FEATURE_PKU is referred to as "PKU" in the hardware documentation:
CPUID.7.0.ECX[3]:PKU. X86_FEATURE_OSPKE is software support for pkeys,
enumerated with CPUID.7.0.ECX[4]:OSPKE, and it reflects the setting of
CR4.PKE(bit 22).
This patch disables CPUID:PKU without ept, because pkeys is not yet
implemented for shadow paging.

Protection keys define a new 4-bit protection key field (PKEY) in bits
62:59 of leaf entries of the page tables, the PKEY is an index to PKRU
register(16 domains), every domain has 2 bits(write disable bit, access
disable bit).
Static logic has been produced in update_pkru_bitmask, dynamic logic need
read pkey from page table entries, get pkru value, and deduce the correct

Currently XSAVE state of host is not restored after VM-exit and PKRU
is managed by XSAVE so the PKRU from guest is still controlling the
memory access even if the CPU is running the code of host. This is
not safe as KVM needs to access the memory of userspace (e,g QEMU) to
do some emulation.
So we save/restore PKRU when guest/host switches.

Pkeys is disabled if CPU is in non-paging mode in hardware. However KVM

'struct timeval' uses a 32 bit field for its 'seconds' value which
will overflow in year 2038 and beyond. This patch replaces the use
of timeval in nosy.c with timespec64 which doesn't suffer from y2038
issue. The code is correct as is - since it is only using the
microseconds portion of timeval. However, this patch does the
replacement as part of a larger effort to remove all instances of
'struct timeval' from the kernel (that would help identify cases
where the code is actually broken).

Upcoming in-kernel VFIO acceleration needs different handling in real

This creates a copy of kvmppc_rm_h_stuff_tce and kvmppc_rm_h_put_tce
in addition to the existing kvmppc_rm_h_put_tce_indirect.
This also fixes linker breakage when only PR KVM was selected (leaving

SDHCI host:
Throughout the years, the numbers of SDHCI variants have increased and so
has also the numbers of SDHCI callbacks/quirks. The purpose of these
callbacks/quirks were to enable SDHCI to deal with variant specific
requirements, but unfortunate this method didn't scale. Instead we have
ended up with a mess. Not only did the code become suboptimal but also
highly fragile.
Lately many discussions of how to move forward with SDHCI has taken place
at the MMC mailing list. Step by step, we aim to turn SDHCI's common code
into a set of library functions. This will enable for optimizations and
allow some of the existing callbacks/quirks to be removed, which also
should help to make the code less fragile.
Therefore I am also really pleased to announce that Adrian Hunter (Intel)
has volunteered to step in as the maintainer for SDHCI.
Future wise, I hope the community around SDHCI will continue to grow and
that this release cycle can be the starting point of moving SDHCI into a
better shape. As a matter of fact, already in this cycle the re-factoring
has begun, but of course there are also fixes and new features included.

- sdhci-acpi: Add support for QCOM controllers
- sdhci-pic32: Add new SDHCI variant for PIC32MZDA
