* x86 setup: print missing CPU features in cleartextH. Peter Anvin2008-02-04
| | | | | | | | | | Instead of obscure numbers, print the list of missing CPU features in cleartext. To conserve space, use a host program (mkcpustr.c) to produce a compact list of mandatory features only. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* x86: unify CPU feature string namesH. Peter Anvin2008-02-04
| | | | | | | | | | | Move the CPU feature string names to a separate file (common to 32 and 64 bits); additionally, make <asm/cpufeature.h> includable by host code in preparation for including the CPU feature strings in the boot code.

* x86: cpuid, msr: use inode mutex instead of big kernel lockH. Peter Anvin2008-02-04

* x86: cpuid: allow querying %ecx-sensitive CPUID levelsH. Peter Anvin2008-02-04
| | | | | | | | | | | | After /dev/*/cpuid was introduced, Intel changed the semantics of the CPUID instruction to be sentitive to %ecx as well as %eax. This patch allows querying of %ecx-sensitive levels by placing the %ecx value in the upper 32 bits of the file position (lower 32 bits always were used for the %eax value.) Signed-off-by: H.

The fix was to replace the annotation of the notifier with __refdata to tell modpost that the reference to a _cpuinit function in the notifier are OK. The unregister call that references the notifier variable will simple delete the function pointer so there is no problem ignoring the reference.
