f47c9a11ad powerpc: Re-work the Implies structure 
This patch tries to organize the implies files for ppc, since there are
a number of processors and most of them are compatible with each other
(backwards compatible).

Having in mind that we start the search for processor-specific files in
the sysdeps/unix/sysv/linux tree
(sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/[processor]/fpu to be
exact), we would like to grab any linux-specific code from that tree
prior to going through the other tree (sysdeps/powerpc/...).

For that, i removed the Implies files that were originally inside the
fpu directories and placed then in the non-fpu directories (still inside
the unix/sysv/linux tree). If no processor-specific/linux-specific files
could be found, we "imply" the other tree's (sysdeps/powerpc/...) fpu
directory for that specific processor AND also the non-fpu directory for
that same tree.

If, again, no processor-specific code is found, we read another Implies
file that will point to the most compatible processor that we should
grab code from, and so on, until we reach the power4 processor.

So, in summary, the Implies files will live inside these directories
now:

* sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/[processor]
* sysdeps/powerpc/powerpc[32|64]/[processor]

Practical example of the order we will use to pick power6-specific code
with the new structure.

sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/power6/fpu ->
sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/power6 ->
sysdeps/powerpc/powerpc[32|64]/power6/fpu ->
sysdeps/powerpc/powerpc[32|64]/power6 ->
sysdeps/powerpc/powerpc[32|64]/power5+/fpu ->
sysdeps/powerpc/powerpc[32|64]/power5+ ->
sysdeps/powerpc/powerpc[32|64]/power5/fpu ->
sysdeps/powerpc/powerpc[32|64]/power5 ->
sysdeps/powerpc/powerpc[32|64]/power4/fpu ->
sysdeps/powerpc/powerpc[32|64]/power4 (from here, it'll go to the
generic path as usual)

6fb8cbcb58 Improve 64bit memcpy/memmove for Atom, Core 2 and Core i7 
This patch includes optimized 64bit memcpy/memmove for Atom, Core 2 and
Core i7.  It improves memcpy by up to 3X on Atom, up to 4X on Core 2 and
up to 1X on Core i7.  It also improves memmove by up to 3X on Atom, up to
4X on Core 2 and up to 2X on Core i7.

It's already so marked in dl-sysdep.c.  Failure to so mark
in the header file leads the compiler to believe that the

c8727fa6e5 Fix Linux getlogin{_r,} implementation 
The old implementation uses fd 0 to determine the login TTY.  This
was needed because using /dev/tty it is not possible to deduce the
login TTY.  For some time now there is the pseudo-file
/proc/self/loginuid which directly helps us to find the user.  Prefer
using this file.  It also works if stdin is closed, redirected, or
re-opened.

If a binary gets invoked by passing it as argument to ld.so the stack
still holds the auxiliary vector of ld.so when entering the _start

transparent to the executable.  This causes problems if the executable
wants to scan the auxv itself.

eb4157390c Update ntp_gettime for Linux. 
The ntp_gettime implementation of NTP exports the tai field the kernel
now produces.  This requires an ABI change since the ntptimeval structure
changed.  Upstream kept the same name, there is nothing to do.  This
patch changes the ntptimeval structure but keeps the old ntp_gettime
definition.  A new ntp_gettimex function which is transparently invoked
through the old name is introduced.  This has the advantage that even
object files can remain compatible.  This wouldn't be the case if
symbol versioning would be used to overload the name ntp_gettime.

I've just committed STT_GNU_IFUNC ppc/ppc64 support into prelink,
and this patch is needed on the glibc side.  Without it ld.so segfaults,
as in dl-conflict.c sym_map is always NULL.  While dl-machine.h could use
RESOLVE_CONFLICT_FIND_MAP macro to compute it, it doesn't make sense,
because with prelink we know it is already properly relocated (all relative
relocations are applied by prelink).

are wrong on 32-bit arches with -D_FILE_OFFSET_BITS=64 and as I've just

The problem is that only off_t is remapped to the 64-bit type transparently,
__off_t is not.

tst-longjmp_chk passes, tst-longjmp_chk2 fails but that is because
of some limitations of kernel signal delivery on sparc that I need
to fix, it has nothing to do with the longjmp_chk implementation.

(The problem with tst-longjmp_chk2 is that it tries to do a stack
 fault SIGSEGV within a stack fault SIGSEGV , and the Linux kernel
 will refuse to setup the signal stack and deliver the signal if the
 register windows can't be written out to the stack first)

84088310ce Handle AVX saving on x86-64 in interrupted smbol lookups. 
If a signal arrived during a symbol lookup and the signal handler also
required a symbol lookup, the end of the lookup in the signal handler reset
the flag whether restoring AVX/SSE registers is needed.  Resetting means
in this case that the tail part of the outer lookup code will try to
restore the registers and this can fail miserably.  We now restore to the
previous value which makes nesting calls possible.

This patch fixes mixed SSE/AVX audit and checks AVX only once in

modified, we have to make sure that the SSE part value is the same in both
lr_xmm and lr_vector fields so that pltexit will get the correct value
from either lr_xmm or lr_vector fields. AVX-enabled pltenter should
update both lr_xmm and lr_vector fields to support stacked AVX/SSE
pltenter functions.

a546baa9cd Properly count number of logical processors on Intel CPUs. 
The meaning of the 25-14 bits in EAX returned from cpuid with EAX = 4
has been changed from "the maximum number of threads sharing the cache"
to "the maximum number of addressable IDs for logical processors sharing
the cache" if cpuid takes EAX = 11.  We need to use results from both
EAX = 4 and EAX = 11 to get the number of threads sharing the cache.

The 25-14 bits in EAX on Core i7 is 15 although the number of logical
processors is 8.  Here is a white paper on this:

http://software.intel.com/en-us/articles/intel-64-architecture-processor-topology-enumeration/

This patch correctly counts number of logical processors on Intel CPUs
with EAX = 11 support on cpuid.  Tested on Dinnington, Core i7 and
Nehalem EX/EP.

It also fixed Pentium Ds workaround since EBX may not have the right
value returned from cpuid with EAX = 1.
