2010-11-18x86-64: Fix and clean up AMD Fam10 MMCONF enablingJan Beulich
Candidate memory ranges were not calculated properly (start addresses got needlessly rounded down, and end addresses didn't get rounded up at all), address comparison for secondary CPUs was done on only part of the address, and disabled status wasn't tracked properly.

2010-11-10x86: Adjust section annotations in AMD Fam10 MMCONF enabling codeJan Beulich
check_enable_amd_mmconf_dmi() gets called only for the BSP, hence everything hanging off of it can be __init*.

2010-02-10x86: Move range related operation to one fileYinghai Lu
We have almost the same code for mtrr cleanup and amd_bus checkup, and this code will also be used in replacing bootmem with early_res, so try to move them together and reuse it from different parts. Also rename update_range to subtract_range as that is what the function is actually doing. -v2: update comments as Christoph requested Signed-off-by: Yinghai Lu <yinghai@kernel.org> LKML-Reference: <1265793639-15071-4-git-send-email-yinghai@kernel.org> Signed-off-by: H.

2009-03-12x86: move various CPU initialization objects into .cpuinit.rodataJan Beulich
Impact: debuggability and micro-optimization Putting whatever is possible into the (final) .rodata section increases the likelihood of catching memory corruption bugs early, and reduces false cache line sharing.

2008-12-29x86, pci: move arch/x86/pci/pci.h to arch/x86/include/asm/pci_x86.hJaswinder Singh Rajput
Impact: cleanup Now that arch/x86/pci/pci.h is used in a number of other places as well, move the lowlevel x86 pci definitions into the architecture include files. (not to be confused with the existing arch/x86/include/asm/pci.h file, which provides public details about x86 PCI) Tested on: X86_32_UP, X86_32_SMP and X86_64_SMP Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-08-18x86: mmconf: fix section mismatch warningMarcin Slusarz
WARNING: arch/x86/kernel/built-in.o(.cpuinit.text+0x1591): Section mismatch in reference from the function init_amd() to the function .init.text:check_enable_amd_mmconf_dmi() The function __cpuinit init_amd() references a function __init check_enable_amd_mmconf_dmi(). If check_enable_amd_mmconf_dmi is only used by init_amd then annotate check_enable_amd_mmconf_dmi with a matching annotation. check_enable_amd_mmconf_dmi is only called from init_amd which is __cpuinit Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: H.

2008-05-25x86: move mmconfig declarations to headerThomas Gleixner
arch/x86/kernel/mmconf-fam10h_64.c is missing the prototypes, which are decalred in arch/x86/kernel/setup_64.c. Move the prototypes and the inline stubs to the appropriate header file. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-26x86: add pci=check_enable_amd_mmconf and dmi checkYinghai Lu
so will disable that feature by default, and only enable that via pci=check_enable_amd_mmconf or for system match with dmi table. Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
