nothing appears to use linux/shm.h and linux/resource.h
strace-4.5.15 uses linux/a.out.h in #ifdef LINUXSPARC
glibc uses asm/elf.h in sys/procfs.h, also in alpha and powerpc.
kexec-tools use linux/elf.h
psmisc and ltrace use linux/user.h
glibc (for sh) and mono-debugger use asm/user.h
And alot of asm/page.h users.
Thats the upstream status today. What you do at home doesnt really
matter.
