M5485 processor
1. Disable mmap2() if we're compiling for coldfire and fall back to mmap().
It seems to map a different file area on a 2.6.25 linux kernel.
2. Uses pc-relative addresing[1], computes ADDR_ALIGN, PAGE_ALIGN
and OFFSET_ALIGN relatively to _dl_pagesize[3].
On coldfire/M5485 _dl_pagesize is 0x2000.

linuxthreads.old/manager: pointless style fixes, no code changes

This patch replaces inline with __inline__ to be more ANSI compatible.

Previously the old headers were left in include/ leading to spurious compile failures.
This is ugly as it can get (we resort to sneaking -L in for the moment) but
good enough for now. The worst thing which can happen is that we ln these
headers once per invocation of make, nothing more.
If some installation of make(1) complains about the "-L" then wrap it in
ifneq ($(findstring check-symlink,$(.FEATURES)),)

- tidy up PTHREADS_DEBUG_SUPPORT by using per-target STRIP_FLAGS for the few
This fixes the spurious rebuilds bernd and vda were seeing with libpthreads.

Since there are more places which want to depend on $(libc), fix them all to
use a new variable $(libc.depend), which contains the filename for which we

libc/inet/ethers.c __ether_line_w() function.
I will wait for fallout reports for a week or so,
then continue converting more libc_hidden_proto's.

rather than the public weak ones so that the libc->libpthread forwarding code is able to work properly
this should fix the case where libpthread.so is not linked directly, but rather via another library:
app -> links to libfoo.so -> links to libpthread.so
and any function (like readdir_r) that does:
__UCLIBC_MUTEX_LOCK()
__UCLIBC_MUTEX_UNLOCK()

gcc version checking in every pt-machine.h header ... while __extern_always_inline should work fine, i think what is intended is __extern_inline ... should double check later

The following patches add support for the Xtensa processor architecture
to uClibc. They are based on a recent SVN checkout (12/05/2007).
The first patch (attached to this post) adds Xtensa support to various
shared configuration and make files. The following patches then include
the Xtensa specific files and directories.
I welcome any feedback and would appreciate it if you could include the
patches into the mainline tree. I am certainly committed to maintain the port.
Bob Wilson was kind enough to review the patches.
Some notes about the architecture: Xtensa is a configurable and
extensible processor architecture developed by Tensilica. For more
information, please visit: www.linux-xtensa.org.
