In ltp testcase sendfile08.c, it use offset=NULL to test the api.
PATCH V2:
fixup the stupid missing check in the end. Sorry for lose test.
See "man sendfile" and it really support offset is NULL.

Those definitions exist on all other architectures, but were not
present in or1k specific headers when or1k support was merged.
On the kernel side, their support is completely architecture
independent, so we just need those definitions to make those fcntl()
calls available on or1k.

Sync with GNU C library and consolidate duplicate non
architecture specific defines.
MAP_UNINITIALIZED is only defined to 0x4000000 and used by
the Linux kernel when CONFIG_MMAP_ALLOW_UNINITIALIZED is enabled.
CONFIG_MMAP_ALLOW_UNINITIALIZED is only available for nommu.

OpenBSD arc4random is using chacha20 cipher algorithm for
a long time. This copy is still based on deprecated rc4
cipher algorithm. We could either update the arc4random.c
or drop it. Drop it. Users should better use libbsd when
using arc4random interface. Musl/glibc does not have arc4random
either.

The fallback code is not used as all supported kernels have the
syscall. Check if a absolute path is returned from syscall.

Loops with 'loop forever' annotation inside strcmp are actually meant to
loop forever. Falling through the end of the first loop may result in
equal strings being compared unequal, e.g.:
#include <string.h>
int main(void)
{
char a[4096] __attribute__((aligned(4)));
char b[4096] __attribute__((aligned(4)));
memset(a, ' ', 258 * 8);
memset(b, ' ', 258 * 8);
a[255 * 8] = 0;
a[256 * 8] = 'a';
b[255 * 8] = 0;
b[256 * 8] = 'b';
return !(strcmp(a, b) == 0);
}
Falling through the end of the second loop may result in unequal strings
being compared as equal, e.g.:
#include <string.h>
int main(void)
{
char a[4096] __attribute__((aligned(4)));
char b[4096] __attribute__((aligned(4)));
memset(a, ' ', 514 * 6);
memset(b, ' ', 514 * 6);
a[514 * 6 + 0] = 'a';
a[514 * 6 + 1] = 0;
b[514 * 6 + 0] = 'b';
b[514 * 6 + 1] = 0;
return !(strcmp(a, b) != 0);
}
Use 0 as a loop counter to make 2^32 - 1 iterations which is enough to
cover all addressable memory. While at it drop useless nop at the end of
the first loop and use a11 for all loop counters.

Traditionally nds32 has had a generic syscall implementation supporting
varargs.
During an audit it was found that this implementation seems to duplicate
the new common implementation and is no longer needed.

Now that the common syscall implementation supports vararg calling
conventions we can safely use it on OpenRISC.
This saves a bit of code in the openrisc implementation.

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.

Port over NPTL/TLS support from GNU C Library.
In the first step only the slower syscall is used for TLS
access. The uClibc-ng testsuite shows 79 errors, so their
is room for bugfixes and improvements.

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.

It is supported both in the sense of being contained in mips version
of statfs/statfs64 structs and also in the sense that it's filled by
the corresponding kernel syscalls.
It is UNsupported in that sense that it's value is the same as that
of f_bsize (at least on older kernel versions, the oldest version
tested is 2.6.13), s. [1] and [2] for details ([1] is the latest
kernel version as of now, [2] is the oldest kernel version git
history is available for).

Follow the steps to build c-sky uclibc linux system:
1. git clone https://github.com/c-sky/buildroot.git
2. cd buildroot
3. make qemu_csky_ck810_uclibc_defconfig
4. make
Follow the buildroot/board/qemu/csky/readme.txt to run.
This buildroot toolchain is pre-build, But you can rebuild
the c-sky uclibc-ng alone and install it to the buildroot
sysroot manually.
We'll try our best to improve the uclibc-ng continuously.
