Subject: [PATCH v4 03/19] ARM: LPAE: use long long format when printing physical addresses and ptes
From: Will Deacon <will.deacon@....com>
Now that the Kernel supports 2 level and 3 level page tables, physical
addresses (and also page table entries) may be 32 or 64-bits depending
upon the configuration.
This patch uses the %08llx conversion specifier for physical addresses
and page table entries, ensuring that they are cast to (long long) so
that common code can be used regardless of the datatype widths.
