Subject: [PATCH] ppc32: make usage of CONFIG_PTE_64BIT & CONFIG_PHYS_64BIT consistent
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a85f6d4aca822acdb49d27c44519cd6514b06a1d;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[PATCH] ppc32: make usage of CONFIG_PTE_64BIT & CONFIG_PHYS_64BIT consistent

CONFIG_PTE_64BIT & CONFIG_PHYS_64BIT are not currently consistently used in
the code base.  Fixed up the usage such that CONFIG_PTE_64BIT is used when we
have a 64-bit PTE regardless of physical address width.  CONFIG_PHYS_64BIT is
used if the physical address width is larger than 32-bits, regardless of PTE
size.

These changes required a few sub-arch specific ifdef's to be fixed and the
introduction of a physical address format string.
