[Cbe-oss-dev] [PATCH] 64K support for Kexec

[Luke Browning]

static inline void __tlbie(unsigned long va, unsigned int psize)
{
        unsigned int penc;

        /* clear top 16 bits, non SLS segment */
        va &= ~(0xffffULL << 48);

why does this routine clear the top 16 bits?  

SLS - single level store.  all segments are non-sls?
