Systrack v0.3

New arch support: PowerPC 64-bit, all ABIs, tested on v5.0+ kernels.

Improvements:

• Add ABI bits (integer) and compat (boolean) fields to JSON output.
• Support ELF symbols with weird names (special chars in the name).
• Support function descriptors for syscall table entries (useful for PowerPC64 and Itanium 64).
• Support weird arch-specific SYSCALL_DEFINEn macros.
• Building kernels now generates relative paths in DWARF debug symbols through -fdebug-prefix-map.
• Improve stdout output and add a table header.
• Use null instead of ??/? for unknown file/line info in JSON output.
• x86: improve dummy syscall implementation detection (handling endbr64/32 instructions).
• ARM OABI: output syscall number location for the calling convention (swi <NR>).

Bug fixes:

• Correctly report socketcall depending on CONFIG_NET=y.
• Correctly strip more syscall symbol prefixes for more accurate syscall names.
• Fix bad symbol prefix detection in some weird edge cases, leading to wrong syscall names.
• x86: fix wrong register names for x86-64 compat 32-bit ABI (IA-32).

Internal changes:

• Reorganize arch-specific code.
• Handle SIGINT for more graceful termination.
• Auto-remap definition locations relative to KDIR for ease of use.

Systrack v0.2.1

Improvements:

• Make syscall symbol preference more consistent (in particular, stop mixing
  __se_sys_xxx and sys_xxx when possible).
• Achieve W3C compliance for HTML output format.

Bug fixes:

• x86: correct wrong syscall numbers for x32 ABI, they should all be ORed with
  0x40000000 (__X32_SYSCALL_BIT).

Systrack v0.2

• Improve existing MIPS build and analysis support: use ip27_defconfig for
  64-bit for NUMA support and strip more symbol prefixes.
• Improve dummy syscall implementation detection (x86-64, arm).
• x86: use the right config for vm86/vm86old syscalls
• Clarify help text for --arch: building with --arch arm creates an
  EABI-only kernel.
• Fix a logging bug that caused not loging syscalls' .origname for not-found
  locations after grepping.
