Subject: [PATCH 2.6] cannot convert region 5 address to physical by clearing bits 63:61
Date: Mon, 13 Oct 2003 20:28:45 +0000 [thread overview]
Message-ID: <marc-linux-ia64-106607712621564@msgid-missing> (raw)
Another no-brainer bug fix snipped out of the quagmire of
the MCA/TLB patch. This one is for 2.6 only, we must use
the new LOAD_PHYSICAL() macro to get the physical address of
the code label that we want to jump to, the INST_VA_TO_PA()
macro just clears the region bits, which only works for region
7 addresses.
