AArch64: Remove asm/ptrace.h inclusion in sys/user.h and sys/procfs.h
This patch fixes an issue observed by the Xen project, where including signal.h exposes various PSR_MODE #defines. This is due to the usage in sys/user.h and sys/procfs.h of the struct user_pt_regs and user_fpsimd_state included via asm/ptrace.h. The namespace pollution this inclusion introduce is already partially fixed with some #undef of the PTRACE_* symbols, but other symbols like the PSR_MODE ones are still present, and undefining them is not safe since a user can include ptrace.h before user.h. My proposition is to define the 2 structures we need in user.h and get rid of the asm/ptrace.h inclusion. Build and make check are clean on AArch64. 2014-05-20 Will Newton <will.newton@linaro.org> Yvan Roux <yvan.roux@linaro.org> * sysdeps/unix/sysv/linux/aarch64/sys/user.h: Remove unused #include of asm/ptrace.h. (PTRACE_GET_THREAD_AREA): Remove #undef. (PTRACE_GETHBPREGS): Likewise. (PTRACE_SETHBPREGS): Likewise. (struct user_regs_struct): New structure. (struct user_fpsimd_struct): New structure. * sysdeps/unix/sysv/linux/aarch64/sys/procfs.h: Remove unused #include of asm/ptrace.h and second #include of sys/user.h. (PTRACE_GET_THREAD_AREA): Remove #undef. (PTRACE_GETHBPREGS): Likewise. (PTRACE_SETHBPREGS): Likewise. (ELF_NGREG): Use new struct user_regs_struct. (elf_fpregset_t): Use new struct user_fpsimd_struct.
