Changelog v9 -> v10 * Update commit message to include the changelog before the SoB tag(s). v8 -> v9 * No changes. v7 -> v8 * Track NE custom error codes for invalid page size, invalid flags and enclave CID. * Update the heartbeat logic to have a listener fd first, then start the enclave and then accept connection to get the heartbeat. * Update the reference link to the hugetlb documentation. v6 -> v7 * Track POLLNVAL as poll event in addition to POLLHUP. v5 -> v6 * Remove "rc" mentioning when printing errno string. * Remove the ioctl to query API version. * Include usage info for NUMA-aware hugetlb configuration. * Update documentation to kernel-doc format. * Add logic for enclave image loading. v4 -> v5 * Print enclave vCPU ids when they are created. * Update logic to map the modified vCPU ioctl call. * Add check for the path to the enclave image to be less than PATH_MAX. * Update the ioctl calls error checking logic to match the NE specific error codes. v3 -> v4 * Update usage details to match the updates in v4. * Update NE ioctl interface usage. v2 -> v3 * Remove the include directory to use the uapi from the kernel. * Remove the GPL additional wording as SPDX-License-Identifier is already in place. v1 -> v2 * New in v2.
