// Multi-fw libhijacker offsets override.
//
// libhijacker's vanilla offsets.cpp hardcodes fw 9.40 kernel-symbol offsets.
// This file replaces it with a multi-fw resolution path : ps5-payload-sdk
// already exposes the absolute kernel virtual addresses at runtime via the
// KERNEL_ADDRESS_* extern globals (auto-populated per-fw from kern.sdk_version,
// see ps5/kernel.h), so the only job here is converting absolute VA -> offset
// from kdata_base — which is what libhijacker's offsets:: namespace expects.
//
// Compile this .o BEFORE -lhijacker on the link line so the linker resolves
// the offsets:: symbols from here and skips the vanilla offsets.cpp.o that
// would otherwise be pulled from libhijacker.a.
//
// Covers every fw the SDK knows about (3.00 -> 12.00 via kstuff). On an
// unknown fw the SDK returns 0 and libhijacker fails cleanly with NULL
// attach — same graceful failure as the old 9.40-hardcoded path on wrong fw.
