aee6626c30 MicroBlaze: Fix BZ17791 - Remove fixed page size macros and others
Microblaze apparently has a variable page size (see thread below) and
should not hard-code any page-size related macros.
Also remove macros that are only used for BFD's trad-core support
which is not relavant for microblaze also according to the thread
starting here:

https://sourceware.org/ml/libc-ports/2013-11/msg00028.html

This patch is neither built nor tested but mirrors a MIPS patch that
fixes the same issue.

Thanks,
Matthew

dd6e8af6ba powerpc: Fix compiler warning on some syscalls
GCC 5.0 emits an warning when using sizeof on array function parameters
and powerpc internal syscall macros add a check for such cases.  More
specifically, on powerpc64 and powerpc32 sysdep.h:

  if (__builtin_classify_type (__arg3) != 5 && sizeof (__arg3) > 8) \
          __illegally_sized_syscall_arg3 (); \

And for sysdeps/unix/sysv/linux/utimensat.c build GCC emits:

error: ‘sizeof’ on array function parameter ‘tsp’ will return size of
‘const struct timespec *’

This patch uses the address of first struct member instead of the struct
itself in syscall macro.

39a12f8db4 posix/regcomp: initialize union structure tag to avoid warning
We see some surprising warnings on tilegx with gcc 4.8.2:

In file included from regex.c:66:0:
regcomp.c: In function ‘parse_expression’:
regcomp.c:2849:15: error: ‘end_elem’ may be used uninitialized in this
function [-Werror=maybe-uninitialized]
       else if (br_elem->type == COLL_SYM)
               ^
regcomp.c:3109:34: note: ‘end_elem’ was declared here
       bracket_elem_t start_elem, end_elem;
                                  ^
regcomp.c:3109:22: error: ‘start_elem’ may be used uninitialized in
this function [-Werror=maybe-uninitialized]
       bracket_elem_t start_elem, end_elem;
                      ^

These warnings are not seen on x86, and in fact if I compile the
preprocessed tile sources with the x86 gcc 4.8.2, I don't see the
warnings.  I do see eqiuvalent warnings if I compile the
x86-preprocessed source code with tilegx gcc 4.8.2.

The fix here is to initialize the union type field appropriately in
a couple of places where we pass a union pointer to a subroutine that
"knows" what type the union is.  Setting the type explicitly seems like
a more robust way to manage such a data structure in any case.

d5b1c5ed8b setenv fix memory leak when setting large, duplicate string (BZ #17658)
glibc maintains a binary tree of environment strings it malloc()ed
itself.  However, it's possible for it to malloc() a string, then find
that an identical string is already in the tree.  In this case, the
memory is leaked and is not freed if the application later calls
__libc_freeres().  Fix this by freeing 'new_value' when it's unneeded.

Test case:
	#include <stdlib.h>
	#include <string.h>

	int main()
	{
		char *p = calloc(100000, 1);
		memset(p, 'A', 99999);
		setenv("TESTVAR", p, 1);
		setenv("TESTVAR", p, 1);
		free(p);
	}

Leak that was reported by valgrind:
	100,008 bytes in 1 blocks are definitely lost in loss record 1 of 1
	   at 0x4C29F90: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
	   by 0x4E6B3D4: __add_to_environ (setenv.c:176)

fb87ee96d7 Fix incorrect mount table entry parsing in __getmntent_r
When mount entry contains only four fields and have more then one space or
tab at the and, mp.mnt_freq and mp.mnt_passno will be set to some specific
values as side effect from parsing of previus mount entry. It is because
sscanf(""," %d %d ", &a, &b) returns -1, but this case is unprocessed.
Values of mp.mnt_freq and  mp.mnt_passno stays unchanged. This patch is
attempt to fix described issue by removing trailing tabs and spaces.

38949026b3 resolv: fix rotate option
The rotate option doesn't work correctly, and only send the query to the
same server (the second in the list). The rotation code in itself is not
broken, but the nsaddrs structure is reinitialized each time at the
beginning of __libc_res_nsend unless RES_STAYOPEN is enabled.

This is due to a call to __res_iclose from the end of __libc_res_nsend
when answers from the name server have been received. This function
closes all the sockets, but doesn't free the addresses (it can do that,
but in that case the second argument is false).

This patch change the code of __res_iclose to clear statp->_u._ext.nsinit
 only when the addresses are actually freed.

	addresses have been freed.

57ada0e7e7 Define CLOCKS_PER_SEC type to the type clock_t
C99 specifies that CLOCKS_PER_SEC is an expression with the type clock_t.
This patch adds a generic <bits/time2.h> to define CLOCKS_PER_SEC and
provides the Linux/x86-64 version of <bits/time2.h> to support x32.

ef9faf1385 Fix libm feholdexcept namespace (bug 17748).
Continuing the fixes for C90 libm functions calling C99 fe* functions,
this patch fixes the case of feholdexcept by making it a weak alias of
__feholdexcept and making the affected code call __feholdexcept.

Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch).  Also tested for ARM
(soft-float) that feholdexcept failures disappear from the
linknamespace test failures (fesetenv, fsetround and feupdateenv
remain to be addressed to complete fixing bug 17748).

ac4c11f580 Fix MIPS n64 posix_fadvise namespace (bug 17796).
sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise.c defines
posix_fadvise64 as a strong alias for posix_fadvise (for
!SHLIB_COMPAT(libc, GLIBC_2_2, GLIBC_2_3_3) - i.e., for static
linking, which is the case when this matters), but it should be a weak
alias.  This patch makes it a weak alias.

Tested for MIPS that this fixes the observed linknamespace test
failures.

7ea793f39c tile: check error properly for vDSO calls
The tile vDSO vsyscalls were not properly setting the error value.
Conventionally, tile returns the same "non-negative success, negative
errno" value that x86 does (in r0), but it also returns "zero or positive
errno" in r1, which is what the regular syscall code checks.  This change
uses that convention for the vDSO calls as well.

1dca195e1c lround: provide cast for wordsize-64 version if needed
Platforms with 64-bit registers where 32-bit values need to have the
high 32 bits set in a particular way need to have an explicit cast
when using the 64-bit sysdeps/ieee754/dbl-64/wordsize-64 version
of llround() as lround().  This includes tilegx32, and likely MIPS.
x32 does not need this, and AArch64 ILP32 will not either.  Require
it to be specified in sysdep.h to be explicit.

ab70da77ea Fix ARM posix_fadvise64 namespace (bug 17793).
ARM posix_fadvise calls __posix_fadvise64_l64, to which
posix_fadvise64 is a strong alias, but posix_fadvise is a POSIX
function and posix_fadvise64 isn't.  This patch changes it into a weak
alias.

Tested for ARM that this fixes the corresponding linknamespace test
failures.

b8986484e4 Fix isblank / isascii / toascii namespace (bug 17635).
Use of isblank brings in isascii and toascii, but isblank is a C99
function and the other two aren't; similarly, isascii and toascii are
UNIX98 functions and bring in isblank, which isn't.  (Not a
conformance issue because of the is* and to* reservation, but still
contrary to glibc practice.)  This patch fixes this by splitting
isblank out of ctype-extn.c to a separate ctype-c99.c.  isblank_l is
also moved to a separate file, ctype-c99_l.c (non-XSI POSIX.1-2008 has
isblank_l, but isascii / toascii are marked OB XSI).  (In principle
all these functions could go in separate files - that's optimal for
static linking - but they are also all very small, and splitting them
all out is not needed to fix the present bug.)

Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch - the ordering in which new and
existing sources are listed in ctype/Makefile is arranged so functions
go in the same order so that this comparison works).

	[BZ #17635]
	* ctype/ctype-c99.c: New file.  isblank implementation moved from
	...
	* ctype/ctype-extn.c: ... here.
