Re: [PATCH V3 4/5] kexec: Add IND_FLAGS macro

[Geoff Levand]

Add a new kexec preprocessor macro IND_FLAGS, which is the bitwise OR of
all the possible kexec IND_ kimage_entry indirection flags.  Having this
macro allows for simplified code in the prosessing of the kexec
kimage_entry items.  Also, remove the local powerpc definition and use
the generic one.
