Pull x86 sgx updates from Dave Hansen:
"The biggest deal in this series is support for a new hardware feature
that allows enclaves to detect and mitigate single-stepping attacks.

There's also a minor performance tweak and a little piece of the
kmap_atomic() -> kmap_local() transition.

Summary:

- Introduce a new SGX feature (Asynchrounous Exit Notification) for
bare-metal enclaves and KVM guests to mitigate single-step attacks

- Increase batching to speed up enclave release

- Replace kmap/kunmap_atomic() calls"

x86/sgx: Allow enclaves to use Asynchrounous Exit Notification

Short Version:

Allow enclaves to use the new Asynchronous EXit (AEX)
notification mechanism. This mechanism lets enclaves run a
handler after an AEX event. These handlers can run mitigations
for things like SGX-Step[1].

AEX Notify will be made available both on upcoming processors and
on some older processors through microcode updates.

Long Version:

== SGX Attribute Background ==

The SGX architecture includes a list of SGX "attributes". These
attributes ensure consistency and transparency around specific
enclave features.

As a simple example, the "DEBUG" attribute allows an enclave to
be debugged, but also destroys virtually all of SGX security.
Using attributes, enclaves can know that they are being debugged.
Attributes also affect enclave attestation so an enclave can, for
instance, be denied access to secrets while it is being debugged.

The kernel keeps a list of known attributes and will only
initialize enclaves that use a known set of attributes. This
kernel policy eliminates the chance that a new SGX attribute
could cause undesired effects.

For example, imagine a new attribute was added called
"PROVISIONKEY2" that provided similar functionality to
"PROVISIIONKEY". A kernel policy that allowed indiscriminate use
of unknown attributes and thus PROVISIONKEY2 would undermine the
existing kernel policy which limits use of PROVISIONKEY enclaves.

== AEX Notify Background ==

"Intel Architecture Instruction Set Extensions and Future
Features - Version 45" is out[2]. There is a new chapter:

Asynchronous Enclave Exit Notify and the EDECCSSA User Leaf Function.

Enclaves exit can be either synchronous and consensual (EEXIT for
instance) or asynchronous (on an interrupt or fault). The
asynchronous ones can evidently be exploited to single step
enclaves[1], on top of which other naughty things can be built.

AEX Notify will be made available both on upcoming processors and
on some older processors through microcode updates.

== The Problem ==

These attacks are currently entirely opaque to the enclave since
the hardware does the save/restore under the covers. The
Asynchronous Enclave Exit Notify (AEX Notify) mechanism provides
enclaves an ability to detect and mitigate potential exposure to
these kinds of attacks.

== The Solution ==

Define the new attribute value for AEX Notification. Ensure the
attribute is cleared from the list reserved attributes. Instead
of adding to the open-coded lists of individual attributes,
add named lists of privileged (disallowed by default) and
unprivileged (allowed by default) attributes. Add the AEX notify
attribute as an unprivileged attribute, which will keep the kernel
from rejecting enclaves with it set.
