This patch fixes the incorrect guard by __USE_MISC of struct winsize and
struct termio in powerpc termios header. Current states leads to build
failures if the program defines _XOPEN_SOURCE, but not _DEFAULT_SOURCE
or either _BSD_SOURCE or _SVID_SOURCE. Without any definition,
__USE_MISC will not be defined and neither the struct definitions.
This patch copies the default Linux ioctl-types.h by adjusting only the
character control field (c_cc) size in struct termio.

uClibc-ng don't build with gcc 9.1 [1] due to a new check that
"catch illegal asm constraint usage" [2].
gcc 9.1 print this error:
"invalid hard register usage between earlyclobber operand and input operand"
The asm constraint is present in uClibc since it support sparc (back in 2002)[3].
Note: There is no such constraint is Glibc counterpart code [4].

preadv/pwritev don't provide separate version for 64-bit wide off_t,
and default to 32-bit wide off_t, which results in a mismatch between
declaration and definition for user programs built with
-D_FILE_OFFSET_BITS=64.
Make offset argument of both functions __off64_t.
This fixes test misc/tst-preadvwritev on xtensa.

I've got several patches to fix ltp/openmp/uclibc-ng-test testcase fail on
c-sky.
- fix a ltp testcase.
- fix the problem that pthread creat will fail when libomp is linked before
libc, the variable pagesize is not init.
- fix tst-cancel4 and tst-cancel16. tst-cancelx4 and tst-cancelx16 still fail
with this patch applied, cleanup handler is not called for open/creat/fcntl,
seems some thing wrong with unwind, I haven't check the rootcause yet.

Fix issues with aarch64 and df with mismatching header between kernel
and libc.
|

On Linux/MIPS (O32 ABI) for system call we have two result registers - v0 and a3.
v0 contains actual syscall result on success or error number on fail, a3 set to 0/1
for indicating syscall success/fail. (if a3 == 1, v0 contains errno).
Now as we can see from definition of handle_sys (arch/mips/kernel/scall32-o32.S),
handler treats returned by syscall function (let's call "original") values in
range [-EMAXERRNO; 0[ as -errno, a3 is set to 1 and final returned (to userspace)
value is (-original).
INLINE_SYSCALL_NOERR_NCS defined in mips/bits/syscalls.h will handle
this behaviour.

Add FDPIC dynamic relocations support, similar to what other FDPIC
targets do.
Lazy binding is implemented in a folllow-up patch.

access constant strings that are unsupported by the existing
arm version.
Define DL_START, START, ARCH_NEEDS_BOOTSTRAP_RELOCS,
DL_CHECK_LIB_TYPE similarly to what other FDPIC targets do.
Define raise() because _dl_find_hash references __aeabi_uidivmod,

Those definitions exist on all other architectures, but were not

On the kernel side, their support is completely architecture

Traditionally nds32 has had a generic syscall implementation supporting

The definition of syscall() in unistd.h is with varargs. Traditionally
the common implementation in uclibc has been with regular arguments.
This patch updates that by using varargs.
This has caused issues on architectures like or1k which have different
calling conventions for varargs and regular arg parameters.
The implementation here is based on an implementation from Joel Stanley
<joel@jms.id.au>. There is a difference that I do not initialize the
stack args with 0 as they are immediately overwritten by va_args.

Busybox internally calls syscall(2).
- in unistd.h defined something like
int syscall(nr, ....)
- in syscall.c (common) implemented as
int syscall(nr, arg1, arg3, arg3, arg4, arg5, arg6)
This will not work, busybox thinks syscall should have varargs calling
conventions. But it doesnt in the uclibc implementation so no args go through.
Most architectures this will work. But on openrisc varargs are all sent on the
stack. Regular args are passed in registers.
