x32/cet: Support shadow stack during startup for Linux 6.10
Use RXX_LP in RTLD_START_ENABLE_X86_FEATURES. Support shadow stack during startup for Linux 6.10: commit 2883f01ec37dd8668e7222dfdb5980c86fdfe277 Author: H.J. Lu <hjl.tools@gmail.com> Date: Fri Mar 15 07:04:33 2024 -0700 x86/shstk: Enable shadow stacks for x32 1. Add shadow stack support to x32 signal. 2. Use the 64-bit map_shadow_stack syscall for x32. 3. Set up shadow stack for x32. Add the map_shadow_stack system call to <fixup-asm-unistd.h> and regenerate arch-syscall.h. Tested on Intel Tiger Lake with CET enabled x32. There are no regressions with CET enabled x86-64. There are no changes in CET enabled x86-64 _dl_start_user. Signed-off-by: H.J.
