Peter Anvin" From: "H. Peter Anvin" The patch series currently in -tip as x86/syscall, which builds syscall tables from a simple text file also broke UML. I intend to apply this patch to tip:x86/syscall, but if the UML folks would either holler or ack that would be appreciated. This patch series enables using generated host header files in UML, and then uses the new x86 generated syscall tables in the same uniform style as the native kernel. The native kernel relies on asm-offsets.h to generate the syscall fencepost symbols automatically (it is done that way rather in the script to make the future extension to multiple supported ABIs work better.) On UML, asm-offsets.h is generated globally, but user-constants.h has per-subarchitecture support; it feels a little like an odd place for it but I put the fenceposts there. The UML folks might want to holler if that is too broken. arch/um/Makefile | 9 +++++- arch/x86/um/Makefile | 3 +- arch/x86/um/sys_call_table_32.S | 26 ------------------ arch/x86/um/sys_call_table_32.c | 55 +++++++++++++++++++++++++++++++++++++++ arch/x86/um/sys_call_table_64.c | 31 ++++++++------------- arch/x86/um/user-offsets.c | 15 ++++++++++ 6 files changed, 91 insertions(+), 48 deletions(-)
