Summary: AMD Family 10h and 11h incorrectly identified in amd.c
Product: ACPI
Version: 2.5
KernelVersion: 2.6.25-rc7
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Config-Processors
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Latest working kernel version: unknown
Earliest failing kernel version: unknown
Distribution: kernel.org
Hardware Environment: AMD Family 10h or Family 11h processor
Software Environment: none
Problem Description: x86 structure memory incorrectly checked in amd.c
Steps to reproduce: Review the source
In the source for 2.6.25-rc7, arch/x86/kernel/cpu/amd.c lines 254 and 255
incorrectly use 0x10 and 0x11 for c->x86 instead of 0x1F and 0x2F respectively.
See setup_64.c at lines 921 and 922:
if (c->x86 == 0x0f)
c->x86 += (tfms >>20) & 0xff;
Kernel 2.6.24.4 is similarly broken, with an additional x86 check for 0x10 at
line 287 when it should be checking for 0x1F.
