 | >Description:
 | LPCIB_ICH5_HPTC_WIN_MASK is a problematic choice of mask.
 | 
 | from sys/dev/ic/i82801lpcreg.h:
 | 
 |  84 #define LPCIB_ICH5_HPTC_WIN_MASK        0x0000c000                       
 
 While changing the mask to 1c000 will remove the warning, the linux code
 is doing something different; see ./arch/x86/kernel/quirks.c
