For some rarely cases(almost App bugs), calling malloc with
a very largre size, checked_request2size check will fail,set
ENOMEM, and return 0 to caller.
But this will let __malloc_lock futex locked and owned by the
caller. In multithread circumstance, other thread calling
malloc/calloc will NOT succeed and get locked.

On execution of "inet/gethost_r-align" test I noticed failure due
to unaligned access (instaed of 4-byte aligned 1-byte aligned
address was attempted to be accessed).
Further investigation confirmed this nice and helpful test failure.
Following commit removed usage of ALIGN_BUFFER_OFFSET on entry to
__read_etc_hosts_r():
http://git.uclibc.org/uClibc/commit/?id=f65e66078b9f4d2d7f0fc336dee36e78fc467c0f
So indeed if target architecture doesn't allow unaligned access
and provided tmp buffer is not word aligned (and we will deal with pointers
which means word-sized data units), then CPU will fail during execution.
In case of ARC we'll see "Unaligned access" exception like this:

Currently UCLIBC_SYSCALL_ALIGN_64BIT is not explicitly handled. Fix that
and make sure the special handling is done for powerpc/xtensa which use
UCLIBC_SYSCALL_ALIGN_64BIT but don't use hole punched syscall handler in
kernel.

arm/powerpc/xtensa pass @advice as 2nd arg to syscall (vs. canonical 4th)
Current code however does this for UCLIBC_SYSCALL_ALIGN_64BIT which
powerpc/xtensa also happen to define.
This is not true for ARCv2 ISA and possibly other arch of future with
64-bit even register requirement, which uses the standard syscall
handler in kernel.
Fix that by providing 2 variants of SYSCALL_ALIGN_64BIT

mkostemp(char *template, int flags) generates a unique temporary
filename from a template. The flags parameter accepts three of
the same flags as open(2): O_APPEND, O_CLOEXEC, and O_SYNC. The
current implementation of mkostemp(3) does not respect the flags
and in fact confuses the flags with the file mode which should
always be S_IRUSR | S_IWUSR. This patch corrects this issue.

We were relying on FE_DIVBYZERO being turned off when printing
"%f", +-.0
Avoid the whole issue by looking at the sign-bit (in a rough
approximation).
Note that we do not handle gracefully:
printf ("\n%llf\n", -0.0);
printf ("\n%llf\n", 0.0);
nor %Lf for both when NOT cast to long double. Avoiding an FPE due to
broken numbers like these does not make sense to me.

statfs() is a Linux-specific function. When building without
UCLIBC_LINUX_SPECIFIC set, libc_hidden_proto(statfs) in
include/sys/statfs.h is unmatched with libc_hidden_def(statfs)
in libc/sysdeps/linux/common/statfs.c, leading to a compile
error. This patch fixes this, as well as adds statfs() to the
list of Linux-specific functions in extra/Configs/Config.in.

We add the Linux-specific function fallocate() which allows the user to
directly manipulate allocate space for a file. fallocate() can operate
in different modes, but the default mode is equivalent to posix_fallocate()
which is specified in POSIX.1.

available.
