Re: [Xen-devel] [PATCH] MTRR MSRs Save/Restore

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

Define a new save/restore structure, with its own save/restore routines,
rather than appending to hvm_hw_vcpu. Do not declare extern functions in .c
files (decalring those functions as save/restore handlers for your new state
structure may get rid of those externs anyway). You cannot include Xen
private header files from public header files, so you cannot get at
<asm/mtrr.h>. You'll need to define appropriate array sizes in the save.h
header file independently of private Xen header files. Hopefully the state
you are saving is architectural and so has 'well known' sizes and ranges
that we won't mind hardcoding in a public header file?
