Message-ID: <3B08F344.333B746C@mips.com> (raw)
In the macros PHYSADDR, KSEG0ADDR, KSEG1ADDR, KSEG2ADDR and KSEG3ADDR in
include/asm-mips64/addrspace.h the addresses are and'ed with
0x000000ffffffffffUL, instead of and'ed with 0x000000001fffffffUL why is
that ?
I do understand the address space is extended in 64 bit mode, but the
macros is used to manipulate KSEG0 and KSEG1 addresses, which is located
between 0xffffffff80000000-0xffffffffbfffffff. So the macros are broken
if you change an address from KSEG1 to KSEG0.
