Pull x86 fixes from Borislav Petkov: - Do not hold fpregs lock when inheriting FPU permissions because the fpregs lock disables preemption on RT but fpu_inherit_perms() does spin_lock_irq(), which, on RT, uses rtmutexes and they need to be preemptible. - Check the page offset and the length of the data supplied by userspace for overflow when specifying a set of pages to add to an SGX enclave * tag 'x86_urgent_for_v6.1_rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/fpu: Drop fpregs lock before inheriting FPU permissions x86/sgx: Add overflow check in sgx_validate_offset_length()
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
