powerpc/time: Fix mftb()/get_tb() for use with the compat VDSO
When we're building the compat VDSO we are building 32-bit code but in
the context of a 64-bit kernel configuration.
To make this work
powerpc/time: Fix mftb()/get_tb() for use with the compat VDSO
When we're building the compat VDSO we are building 32-bit code but in
the context of a 64-bit kernel configuration.
To make this work we need to be careful in some places when using
ifdefs to differentiate between CONFIG_PPC64 and __powerpc64__.
CONFIG_PPC64 indicates the kernel we're building is 64-bit, but it
doesn't tell us that we're currently building 64-bit code - we could
be building 32-bit code for the compat VDSO.
On the other hand __powerpc64__ tells us that we are currently
building 64-bit code (and therefore we must also be building a 64-bit
kernel).
In the case of get_tb() we want to use the 32-bit code sequence
regardless of whether the kernel we're building for is 64-bit or
32-bit, what matters is the word size of the current object. So we
need to check __powerpc64__ to decide if we use mftb() or the
mftbu()/mftb() sequence.
For mftb() the logic for CPU_FTR_CELL_TB_BUG only makes sense if we're
building 64-bit code, so guard that with a __powerpc64__ check.
