mainline inclusion from mainline-v6.7-rc1 commit 2fd0ebad27bcd4c8fc61c61a98d4283c47054bcf category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8YHN7
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id...
--------------------------------
commit c35559f94ebc ("x86/shstk: Introduce map_shadow_stack syscall") recently added support for map_shadow_stack() but it is limited to x86 only for now. There is a possibility that other architectures (namely, arm64 and RISC-V), that are implementing equivalent support for shadow stacks, might need to add support for it.
Independent of that, reserving arch-specific syscall numbers in the syscall tables of all architectures is good practice and would help avoid future conflicts. map_shadow_stack() is marked as a conditional syscall in sys_ni.c. Adding it to the syscall tables of other architectures is harmless and would return ENOSYS when exercised.
Note, map_shadow_stack() was assigned #453 during the merge process since #452 was taken by fchmodat2().
For Powerpc, map it to sys_ni_syscall() as is the norm for Powerpc syscall tables.
For Alpha, map_shadow_stack() takes up #563 as Alpha still diverges from the common syscall numbering system in the other architectures.
