2008-10-31x86/voyager: fix missing cpu_index initialisationJames Bottomley
Impact: fix /proc/cpuinfo output on x86/Voyager Ever since | commit 92cb7612aee39642d109b8d935ad265e602c0563 | Author: Mike Travis <travis@sgi.com> | Date: Fri Oct 19 20:35:04 2007 +0200 | | x86: convert cpuinfo_x86 array to a per_cpu array We've had an extra field in cpuinfo_x86 which is cpu_index. Unfortunately, voyager has never initialised this, although the only noticeable impact seems to be that /proc/cpuinfo shows all zeros for the processor ids. Anyway, fix this by initialising the boot CPU properly and setting the index when the secondaries update.

2008-10-30x86: fix /dev/mem mmap breakage when PAT is disabledRavikiran G Thirumalai
Impact: allow /dev/mem mmaps on non-PAT CPUs/platforms Fix mmap to /dev/mem when CONFIG_X86_PAT is off and CONFIG_STRICT_DEVMEM is off mmap to /dev/mem on kernel memory has been failing since the introduction of PAT (CONFIG_STRICT_DEVMEM=n case). Seems like the check to avoid cache aliasing with PAT is kicking in even when PAT is disabled. The bug seems to have crept in 2.6.26. This patch makes sure that the mmap to regular kernel memory succeeds if CONFIG_STRICT_DEVMEM=n and PAT is disabled, and the checks to avoid cache aliasing still happens if PAT is enabled.

2008-10-30MIPS: Sort out CPU type to name translation.Ralf Baechle
As noticed by David Daney <ddaney@caviumnetworks.com>, the old long switch statement did not comply with the Linux C coding style. It was also yet another place of code to be changed when adding a new processor type leading to annoying bugs for example in /proc/cpuinfo. Fixed by moving the setting of the CPU type string into the core of the probing code and a few BUG_ON() test to ensure the CPU probing code indeed did its job and removing multiple now redundant tests.
