    gcov: enable GCOV_PROFILE_ALL for x86_64 · 7bf99fb6
    Peter Oberparleiter authored
    
    
    Enable gcov profiling of the entire kernel on x86_64. Required changes
    include disabling profiling for:
    
    * arch/kernel/acpi/realmode and arch/kernel/boot/compressed:
      not linked to main kernel
    * arch/vdso, arch/kernel/vsyscall_64 and arch/kernel/hpet:
      profiling causes segfaults during boot (incompatible context)
