Add a new tain flag that indicates wheather the user has loaded ACPI
SSDT overlays. This will provide a clean indication in bug reports that
the user has added new information to the ACPI tables.

This patch set enables custom ACPI board configuration by adding
mechanisms in the Linux kernel for loading user defined SSDTs.
In order to support ACPI open-ended hardware configurations we need a
way to augment the ACPI configuration provided by the firmware
image. A common example is connecting
If the ACPI tables changes as a result of a dinamically loaded table and
a bus rescan is required the enumeration/visited flag are not
consistent.
I2C/SPI are not directly enumerated in acpi_bus_attach(), however the
visited flag is set. This makes it impossible to check if an ACPI device

This patch adds supports for I2C device enumeration and removal via

Add support for acpi_user_table configfs items that allows the user to

No need to screw with kmap() in the caller; moreover, when it comes to actual

Sure.
fuse_direct_io() expects this to return either 0 or a negative
error code, but on success it may return a positive value.
fuse_direct_io() may return this same value when the subsequent
I/O operation doesn't transfer any data, which means that it will
return a positive value when no bytes were tran

RDPID is a new instruction that reads MSR_TSC_AUX quickly. This
should be considerably faster than reading the GDT. Add a
cpufeature for it and use it from __vdso_getcpu when available.
