[RESEND PATCH v2 0/2] scripts/gdb: clarify the platforms supporting lx_current and add arm64 support

[Barry Song]

lx_current depends on per_cpu current_task variable which exists on x86 only.
so it actually works on x86 only. the 1st patch documents this clearly; the
2nd patch adds support for arm64.
