Subject: x86_64: Put allocated ELF notes in read-only data segment
From: Roland McGrath <roland@xxxxxxxxxx>
This changes the x86_64 linker script to use the asm-generic NOTES macro so
that ELF note sections with SHF_ALLOC set are linked into the kernel image
along with other read-only data. The PT_NOTE also points to their location.
This paves the way for putting useful build-time information into ELF notes
that can be found easily later in a kernel memory dump.
