[PATCH v14 08/19] signal: x86/sgx: Add SIGSEGV siginfo code for SGX EPCM fault

2018-09-25 Thread Jarkko Sakkinen
From: Sean Christopherson The SGX Enclave Page Cache Map (EPCM) is a hardware-managed table that enforces accesses to an enclave's EPC page in addition to the software-managed kernel page tables, i.e. the effective permissions for an EPC page are a logical AND of the kernel's page tables and the
