[Crash-utility] [PATCH 3/3] arm64: simplify pud description

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Crash only supports 4-level page table translation for 4K page now.
We use pud only when we use 4-level page table translation.
Thus, we can use page table level flag to know if we need
pud or not.
