[BZ #1978]
2005-12-16 Thorsten Kukuk <kukuk@suse.de> [BZ #1978] * sysdeps/unix/sysv/linux/internal_statvfs.c (__statvfs_getflags): Map more filesystem types to a string. * sysdeps/unix/sysv/linux/linux_fsinfo.h: Add SYSFS_MAGIC. 2005-12-19 Jakub Jelinek <jakub@redhat.com> * locale/Makefile (programs/%-kw.h): Run $(GPERF) inside of the programs subdirectory. * sysdeps/powerpc/powerpc32/__longjmp-common.S (__longjmp): Use PTR_DEMANGLE for PC if defined. * sysdeps/powerpc/powerpc64/__longjmp-common.S (__longjmp): Likewise. * sysdeps/unix/sysv/linux/ia64/__longjmp.S (__longjmp): Likewise. * sysdeps/s390/s390-32/__longjmp.c (__longjmp): Xor %r14 with THREAD_GET_POINTER_GUARD () if PTR_DEMANGLE is defined. * sysdeps/s390/s390-64/__longjmp.c (__longjmp): Likewise. * sysdeps/powerpc/powerpc32/setjmp-common.S (__sigsetjmp): Use PTR_MANGLE for PC if defined. * sysdeps/powerpc/powerpc64/setjmp-common.S (__sigsetjmp): Likewise. * sysdeps/s390/s390-32/setjmp.S (__sigsetjmp): Likewise. Avoid call to __sigjmp_save if IS_IN_rtld. * sysdeps/s390/s390-32/elf/setjmp.S (__sigsetjmp): Likewise. * sysdeps/s390/s390-64/setjmp.S (__sigsetjmp): Likewise. * sysdeps/s390/s390-64/elf/setjmp.S (__sigsetjmp): Likewise. * sysdeps/unix/sysv/linux/ia64/setjmp.S (__sigsetjmp): Likewise. * sysdeps/unix/sysv/linux/ia64/sysdep.h (PTR_MANGLE, PTR_DEMANGLE): Define. * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h: Include tls.h. (PTR_MANGLE, PTR_DEMANGLE): Define. * sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h: Include tls.h (PTR_MANGLE, PTR_DEMANGLE): Define. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h: Include tls.h. (PTR_MANGLE, PTR_DEMANGLE): Define. (SYSCALL_ERROR_HANDLER): Add missing semicolons. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h: Include tls.h. (PTR_MANGLE, PTR_DEMANGLE): Define. * sysdeps/unix/sysv/linux/s390/s390-64/socket.S (__socket): Add SYSCALL_ERROR_HANDLER. 2005-12-19 Ulrich Drepper <drepper@redhat.com> * sysdeps/unix/sysv/linux/sparc/sparc32/socket.S: Handle NO_WEAK_ALIAS. * sysdeps/unix/sysv/linux/sparc/sparc64/socket.S: Likewise. Patch by Clint Adams. 2005-12-16 Martin Schwidefsky <schwidefsky@de.ibm.com> * sysdeps/unix/sysv/linux/s390/sys/user.h: Copy struct user and dependent definitions from the kernel header to sys/user.h and remove the #include of asm/user.h.
