During normal runtime, the "ksgxd" daemon behaves like a version of kswapd just for SGX. But, before it starts acting like kswapd, its first job is to initialize enclave memory. Currently, the SGX boot code places each enclave page on a epc_section->init_laundry_list. Once it starts up, the ksgxd code walks over that list and populates the actual SGX page allocator. However, the per-section structures are going away to make way for the SGX NUMA allocator. There's also little need to have a per-section structure; the enclave pages are all treated identically, and they can be placed on the correct allocator list from metadata stored in the enclave page (struct sgx_epc_page) itself. Modify sgx_sanitize_section() to take a single page list instead of taking a section and deriving the list from there.

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.
