Fix preprocessor indentation
...
Indent the C preprocessor directives to reflect their nesting
using the following script:
$ cppi -l $(git grep -El '^[[:space:]]*#[[:space:]]*(if|ifdef|ifndef|elif|else|endif|define|pragma)[[:space:]]' |grep -v '\.sh$') |while read f; do
cppi < "$f" > "$f".cppi; mv "$f".cppi "$f"
done

Move is_negated_errno() to new header negated_errno.h

Move is_negated_errno() to a separate new header file negated_errno.h
and include it just for architectures which require it.
is_negated_errno() is not used on those architectures
that have a dedicated register to signal a syscall error.
The issue was raised when compiling with clang, which is more
strict regarding semantics of unused static inline functions
defined in C files and will issue a -Wunused-function warrning
if they are not used anywhere.

aarch64: make arm registers unsigned

Follow the x86_64 example and define registers in arm_pt_regs
as unsigned, to avoid potential sign extension bugs.
This also fixes --enable-gcc-Werror build.

from int to uint32_t.

Cleanup print_pc
...
Apparently, there are only two types of instruction pointer printers
depending on the architecture: those that print a register that was
fetched earlier, and those that fetch a register themselves using upeek.
With this change, architectures of the first type have ARCH_PC_REG
defined in their arch_regs.c file, architectures of the first type
have ARCH_PC_PEEK_ADDR defined there, and the common code in syscall.c
uses these macros to print the instruction pointer.
