sgx_encl_ewb_cpumask() is no longer unique to the reclaimer where it is used during the EWB ENCLS leaf function when EPC pages are written out to main memory and sgx_encl_ewb_cpumask() is used to learn which CPUs might have executed the enclave to ensure that TLBs are cleared. Upcoming SGX2 enabling will use sgx_encl_ewb_cpumask() during the EMODPR and EMODT ENCLS leaf functions that make changes to enclave pages. The function is needed for the same reason it is used now: to learn which CPUs might have executed the enclave to ensure that TLBs no longer point to the changed pages. Rename sgx_encl_ewb_cpumask() to sgx_encl_cpumask() to reflect the broader usage.

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.
