The patch titled
Subject: ksm: remove dedicated macro KSM_FLAG_MASK
has been removed from the -mm tree. Its filename was
ksm-remove-dedicated-macro-ksm_flag_mask.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Miaohe Lin <linmiaohe@xxxxxxxxxx>
Subject: ksm: remove dedicated macro KSM_FLAG_MASK
The macro KSM_FLAG_MASK is used in rmap_walk_ksm() only. So we can
replace ~KSM_FLAG_MASK with PAGE_MASK to remove this dedicated macro and
make code more consistent because PAGE_MASK is used elsewhere in this
file.
