+Subject: [PATCH] util: fix building when glibc has a stub process_vm_readv
+
+If you have a newer glibc which provides process_vm_readv, but it is built
+against older kernel headers which lack __NR_process_vm_readv, the library
+will contain a stub implementation that just returns ENOSYS. Autoconf
+checks for this case explicitly and will declare it as unavailable. So we
+end up in a case where the headers provide the prototype, but autoconf has
+not defined HAVE_PROCESS_VM_READV, so we hit the same build failure again:
+
+util.c:738:16: error: static declaration of 'process_vm_readv' follows non-static declaration
+/usr/include/bits/uio.h:58:16: note: previous declaration of 'process_vm_readv' was here
+
+So rename our local function to something unique, and add a define so the
+callers all hit the right place.
+
+* util.c (strace_process_vm_readv): Rename from process_vm_readv.
+(process_vm_readv): Define to strace_process_vm_readv.

+Subject: [PATCH] x32: update syscall table
+
+This syncs with the syscall table as it is in linux 3.4.
+
+* linux/x32/syscallent.h (59): Fix comment typo.
+(78): Add missing getdents entry.
+(174): Delete create_module entry (not in the kernel).
+(181, 182, 183, 184, 185): Add missing entries.
+(524, 536, 539, 540): Fix spacing.
