New MISRA C:2012 R10.3 violations due to XSA-438 fix

[Nicola Vetrini <nicola.vetrini@xxxxxxxxxxx>]

Hi all,

In light of the recent changes introduced by commit 
fb0ff49fe9f784bfee0370c2a3c5f20e39d7a1cb,
as part of XSA-438 [1], the signature of function pointer 'update_cr3' 
in
'xen/arch/x86/include/asm/paging.h', line 121, changed its second 
parameter to a boolean.
Consequently, all calls to that function should use a boolean to comply 
with MISRA C:2012
Rule 10.3 ("The value of an expression shall not be assigned to an 
object with a narrower
essential type or of a different essential type category"), but they 
still use integers.
These were the ones I can find:
xen/arch/x86/include/asm/paging.h:299:    return 
paging_get_hostmode(v)->update_cr3(v, 1, noflush);
xen/arch/x86/mm/hap/hap.c:797:    hap_update_cr3(v, 0, false);
xen/arch/x86/mm/shadow/common.c:2513:    
v->arch.paging.mode->update_cr3(v, 0, false);
xen/arch/x86/mm/shadow/multi.c:2478:        
v->arch.paging.mode->update_cr3(v, 0, false);
