* Build posix_fadvice{64} only when UCLIBC_HAS_ADVANCED_REALTIME is set.Khem Raj2009-10-125-9/+22
| | | | | | | | | | Right now for ARM, MIPS, Xtensa and powerpc posix_fadvise routines are included conditionally. They should only be enabled when UCLIBC_HAS_ADVANCED_REALTIME is set.

* Fix daemon build for no-MMU no-threads.Joseph Myers2009-10-121-0/+1
| | | | | | | | | | CLONE_VM (used in no-MMU daemon) is defined in <bits/sched.h>. A build with threads ends up including <sched.h> via <pthread.h> via <bits/uClibc_mutex.h>; this indirect include does not happen for a build without threads, so this patch adds a direct <sched.h> include.

* enable nanosecond stat support for everyoneMike Frysinger2009-10-1235-409/+292
| | | | | | | | | | | | | | Fill out the stat structure so that the nanosecond resolution support is always available. There is a small code size increase for a few ports (three additional assignments in xstatconv), but otherwise everything should remain the same. While we're here, punt __old_kernel_stat from the few headers that still define it as it is unused in uClibc and causes compile errors after these nanosecond changes.

* enable sbrk() for everyoneMike Frysinger2009-10-122-9/+0
| | | | | | | | | | The sbrk() function can be used to merely query sizes and for that, no-mmu works the same as mmu. It can also sometimes increase data segments on no-mmu systems provided the trailing memory is free. So, there is no real reason to exclude this function for no-mmu ports.

| | | | | | | | | | | | | | | | | | The order of attributes in a function definition matters and in a few places in the Blackfin code, it was being applied to the return type instead of the function itself.

* Blackfin: add elf_machine_load_address() stubMike Frysinger2009-10-121-0/+8
| | | | | | | | | | | | The Blackfin port never defined elf_machine_load_address() because the one place this code is called never matters to us.

* i386: store errno value before using __set_errno()Ingo van Lil2009-10-121-4/+3
| | | | | | | | | | | | The __syscall_error() function stores the errno value in the edx register before invoking the __set_errno() macro. When using the pthread library this macro calls thread_self() to determine the errno location, which might clobber the edx register. The errno value must be stored in a "real" variable so the compiler can take care of saving/restoring it if necessary.
