The first $ARCH to move to 2-step de-compressor for ELF main programs. De-compressor uses memfd_create to comply with strictest SELinux settings (no PROT_WRITE on any PROT_EXEC page). First step de-compressor always uses NRV2B to de-compress the second step, and the second step can use a different de-compressor for each PT_LOAD. modified: p_lx_elf.cpp modified: stub/Makefile modified: stub/src/amd64-linux.elf-fold.lds modified: stub/src/amd64-linux.elf-entry.S modified: stub/src/amd64-linux.elf-fold.S new file: stub/src/amd64-linux.elf-main2.c modified: stub/amd64-linux.elf-entry.h modified: stub/amd64-linux.elf-fold.h modified: stub/tmp/amd64-linux.elf-entry.bin.dump modified: stub/tmp/amd64-linux.elf-fold.map
