Re: [Crash-utility] [PATCH v2] arm64: Use CONFIG_ARM64_VA_BITS to initialize VA_BITS_ACTUAL
-----Original Message-----
We can get VA_BITS_ACTUAL from CONFIG_ARM64_VA_BITS by guess.
Without this patch, we may need to use "--machdep vabits_actual=48" to
set the VA_BITS_ACTUAL.

v1 --> v2:
Remove the DISKDUMP limit.
Thanks for the v2 patch, it looks good to me.
