On some historic 32-bit platforms (and 64-bit SuperH), __NR_getrlimit
corresponds to a non-SuS-compatible version that uses a hardcoded value
of 0x7fffffff as infinity. Moreover, in order to provide a backwards
compatibility with that behaviour, some architectures (mips, sparc, and
alpha, with latter being especially peculiar in its ways) just defined
RLIM_INFINITY to that value (with alpha defining RLIM_INFINITY to 2^63-1)
instead of employing sys_old_getrlimit syscall and providing
__NR_ugetrlimit with proper implementation, as other arches did.
Overall, that led to conclusion that printing "RLIM_INFINITY" is never
enough and the actial value should be printed as well.

Commit v4.23~10 has broken the build with Android's libc because it

headers that include <linux/signal.h> could be included along with libc

Fixes: v4.15~126 "Implement arch specific methods of changing syscall number and error code"
The current way of designation of 64-bit specific syscalls in x32
personality not only conflicts with fault injection specification
syntax, but also makes it impossible to specify such syscalls at all
(since everything that starts from a digit is considered a syscall
number specification). So, let's change prefix to suffix and use
octothorpe instead of colon as a separator.
* linux/x32/syscallent.h (13, 15, 16, 19, 20, 45, 46, 47, 54, 55, 59,

If Thumb code is being generated and frame pointers are enabled, the
Thumb frame pointer in r7 clashes with any local variable which may
need to be assigned to r7 (e.g. the syscall NR when making a raw
syscall).
With gcc, the double use of r7 results in a build error, e.g.
strace-4.22/tests/inject-nf.c:86:1: error: r7 cannot be used in asm here
With clang, the double use of r7 can result in the compiler silently
generating broken code which crashes at run time due to frame pointer
corruption:
https://bugs.llvm.org/show_bug.cgi?id=34165
In most cases the problem isn't visible as frame pointers will be
disabled automatically due to optimisation level. However to handle
cases where frame pointers are enabled (e.g. when CFLAGS etc are set
to support a debug build, etc) provide a version of raw_syscall_0
which manually saves and restores the frame pointer value in r7
to a temporary register before setting up the syscall NR in r7
and invoking the syscall.
* linux/arm/raw_syscall.h (raw_syscall_0) [__thumb__]: Provide
an alternative version.
