321029f1c3 sparc64: Fix msgrcv()
msgrcv() does not work on sparc64, as it passes the 6th argument using
the ipc kludge, while the kernel waits for a 6 arguments syscall. This
patches fixes the problem by using a sparc64 specific version of
msgrcv.c.

3a56ea2673 ld.so: Adjust the auxv if ld.so is directly invoked.
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
routine of the executable.  So the invocation via ld.so is not fully
transparent to the executable.  This causes problems if the executable
wants to scan the auxv itself.

The pt_chown program is completely transparently called.  It might

but the needed descriptor and connect stdin, stdout, and stderr
with /dev/null.  pt_chown shouldn't print anything when called to

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.

872873d48d Fix R_PPC64_{JMP_IREL,IRELATIVE} handling in dl-conflict.c.
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).

34df851b33 Fix preadv, pwritev and fallocate for -D_FILE_OFFSET_BITS=64.
As reported in http://bugzilla.redhat.com/533063 , preadv/pwritev prototypes
are wrong on 32-bit arches with -D_FILE_OFFSET_BITS=64 and as I've just
found, fallocate is wrong too.
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)

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

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

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.

b48a267b8f Preserve SSE registers in runtime relocations on x86-64.
SSE registers are used for passing parameters and must be preserved
in runtime relocations.  This is inside ld.so enforced through the
tests in tst-xmmymm.sh.  But the malloc routines used after startup
come from libc.so and can be arbitrarily complex.  It's overkill
to save the SSE registers all the time because of that.  These calls
are rare.  Instead we save them on demand.  The new infrastructure
put in place in this patch makes this possible and efficient.

The test is probably too pessimistic.  All code linked into ld.so

faster SSE-using functions in parts of ld.so.
