Alexander Stein	3372f5a7d0	m68k: Do not set global share for non-kernel shared pages If the SG bit is set in MMUTR the page is accessible for all userspace processes (ignoring the ASID). So a process might randomly access a page from a different process which had a shared page (from shared memory) in its context.

m68k: Do not set global share for non-kernel shared pages

If the SG bit is set in MMUTR the page is accessible for all
userspace processes (ignoring the ASID). So a process might randomly
access a page from a different process which had a shared page
(from shared memory) in its context.

m68k: ColdFire V4e MMU paging init code and miss handler

The different ColdFire V4e MMU requires its own dedicated paging init
code, and a TLB miss handler for its software driven TLB.
