There were multiple copy of the same code spread over the different architectures handling the vDSO. This patch is merging the duplicated code in arch/*/vdso-pie.c and arch/*/include/asm/vdso.h in the common files and let only the architecture specific part in the arch/*/* files. The file are now organized this way: include/asm-generic/vdso.h contains basic definition which could be overwritten by architectures. arch/*/include/asm/vdso.h contains per architecture definitions. It may includes include/asm-generic/vdso.h pie/util-vdso.c include/util-vdso.h These files contains code and definitions common to both criu and the parasite code. The file include/util-vdso.h includes arch/*/include/asm/vdso.h. pie/parsite-vdso.c include/parasite-vdso.h contains code and definition specific to the parasite code handling the vDSO. The file include/parasite-vdso.h includes include/util-vdso.h. arch/*/vdso-pie.c contains the architecture specific code installing the vDSO trampoline. vdso.c include/vdso.h contains code and definition specific to the criu code handling the vDSO. The file include/vdso.h includes include/util-vdso.h.
