It looks the patch is not in mainline or linux-next yet:
% git show linus/master:arch/x86/include/asm/pgtable-3level.h |grep -C3 CONFIG_PARAVIRT
}
#if !defined(CONFIG_SMP) || (defined(CONFIG_HIGHMEM64G) && \
defined(CONFIG_PARAVIRT))
static inline void native_pud_clear(pud_t *pudp)
{
}
% git show linux-next/master:arch/x86/include/asm/pgtable-3level.h |grep -C3 CONFIG_PARAVIRT
}
#if !defined(CONFIG_SMP) || (defined(CONFIG_HIGHMEM64G) && \
defined(CONFIG_PARAVIRT))
static inline void native_pud_clear(pud_t *pudp)
{
}
Thanks,
Fengguang
