      xen: annotate functions which only call into __init at start of day · 44b46c3e
      由 Ian Campbell 提交于 
      Both xen_hvm_init_shared_info and xen_build_mfn_list_list can be
called at resume time as well as at start of day but only reference
__init functions (extend_brk) at start of day. Hence annotate with
__ref.

    WARNING: arch/x86/built-in.o(.text+0x4f1): Section mismatch in reference
        from the function xen_hvm_init_shared_info() to the function
        .init.text:extend_brk()
    The function xen_hvm_init_shared_info() references
    the function __init extend_brk().
    This is often because xen_hvm_init_shared_info lacks a __init
    annotation or the annotation of extend_brk is wrong.

xen_hvm_init_shared_info calls extend_brk() iff !shared_info_page and
initialises shared_info_page with the result. This happens at start of
day only.

    WARNING: arch/x86/built-in.o(.text+0x599b): Section mismatch in reference
        from the function xen_build_mfn_list_list() to the function
        .init.text:extend_brk()
    The function xen_build_mfn_list_list() references
    the function __init extend_brk().
    This is often because xen_build_mfn_list_list lacks a __init
    annotation or the annotation of extend_brk is wrong.

(this warning occurs multiple times)

xen_build_mfn_list_list only calls extend_brk() at boot time, while
building the initial mfn list list

      xen p2m: annotate variable which appears unused · 6b08cfeb
      由 Ian Campbell 提交于 
       CC      arch/x86/xen/p2m.o
arch/x86/xen/p2m.c: In function 'm2p_remove_override':
arch/x86/xen/p2m.c:460: warning: 'address' may be used uninitialized in this function
arch/x86/xen/p2m.c: In function 'm2p_add_override':
arch/x86/xen/p2m.c:426: warning: 'address' may be used uninitialized in this function

In actual fact address is inialised in one "if (!PageHighMem(page))"
statement and used in a second and so is always initialised before
use.

      xen: events: mark cpu_evtchn_mask_p as __refdata · b052181a
      由 Ian Campbell 提交于 
      This variable starts out pointing at init_evtchn_mask which is marked
__initdata but is set to point to a non-init data region in xen_init_IRQ
which is itself an __init function so this is safe.
