25e6a31004 i386 stub: prefer movzbl over movb fetch 
32-bit mode on x86_64 hardware can fail movb fetch to register
by writing 0x00 randomly instead of the fetched byte.
Note that most CPU can write only 32 or 64 bits to the register file,
so writing just 8 or 16 bits incurs a 1-cycle penalty in order to
form 32 bits by Read-Modify-Write of the destination register.

c36977f0b1 ELF: amd64-linux main programs use 2-step de-compressor 
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.
