Generally speaking, I'd much prefer anyone who adds a syscall to update asm-generic/unistd.h as well (as documented in Documentation/adding-syscalls.txt), there is no need for me to put those patches into the asm-generic git tree first. On a related topic, I've been thinking (for years) about coming up with a way to have all future syscalls just get added to a single file in the kernel to have them appended to the tables for all architectures. There are two basic methods that seem appropriate here for avoiding the split between unistd.h and syscalls.S: a) The current asm-generic method of interleaving the __NR_* macro definitions and the entry in a .c file array, including the header multiple times to get all the tables b) generating both files from an input like x86 does with arch/x86/entry/syscalls/ infrastructure I think we need something similar to b) but with some extensions to allow extending the architecture specific tables in a nice way, rather than having to have one file per architecture.
