As soon as the kernel will support the XSAVE extensions in Skylake
processors, we will want both userspace and the hypervisor to run
guests without showing any trace of the new features (because
support for them in the hypervisor will come later).
This series does exactly this. Patches 1 and 3 en
This makes the interface more deterministic for userspace, which can expect
(after configuring only the features it supports) to get exactly the same
state from the kernel, independent of the host CPU and kernel version.

XSAVE entries that KVM does not support are reported by
KVM_GET_SUPPORTED_CPUID for leaf 0Dh index 0 if the host supports them;
they should be left out unless there is also hypervisor support for them.
Sub-leafs are correctly handled in supported_xcr0_bit, fix index 0
to match.

The perf_evlist__mmap_read used 'union perf_event'

This is ok for sample shorter than ~PATH_MAX. However

Fix off-by-one in the equation to calculate max_uV and also adjust the _min_uV
setting accordingly.
For LDOs:
The voltage select bits set the LDO output voltage 0.825V...3.3V, 25mV steps
00h : LDO off
01h-24h : V_LDO4 = 0.8V + ldo4_vsel * 25mV
= 0.825V + (ldo4_vsel - 1h)

The CONFIG_64BIT requirement on vtime can finally be removed

From: Kevin Hilman
With VIRT_CPU_ACCOUNTING_GEN, cputime_t becomes 64-bit. In order
to use that feature, arch code should be audited to ensure there are no
races in concurrent read/write of cputime_t. For example,
reading/writing 64-bit cputime_t on some 32-bit arches may require

With the 64-bit requirement removed from VIRT_CPU_ACCOUNTING_GEN,

This patch adds a pci stub driver to hyper-fb. The hyperv framebuffer
driver will bind to the pci device then, so linux kernel and userspace
know there is a proper kernel driver for the device active. lspci shows
this for example:

Instead of delaying inode initialization until first ->open(), we can use
an anonymous inode. This avoids modifying FS internal inode fields and
provides us a private address_space right during initialization.
Delayed TTM dev_mapping initialization is currently left untouched to keep
this simple.
DRM core shares a single address_space across all inodes that belong to
the same DRM device. This allows efficient unmapping of user-space
mappings during buffer eviction. However, there is no easy way to get a
shared address_space for DRM devices during initialization. Therefore, we
currently dela

If writeback happens while fuse is in FUSE_NOWRITE condition, the request
will be queued but not processed immediately (see fuse_flush_writepages()).
Until FUSE_NOWRITE becomes relaxed, more writebacks can happen. They will
be queued as "secondary" requests to that first ("primary") request.

Hi,
I tried using the `perf timechart` command after a `sudo perf

All async fuse requests must be supplied with extra reference to a fuse file.
This is necessary to ensure that the fuse file is not released until all
in-flight requests are completed. Fuse secondary writeback requests must
obey this rule as well.
