[merged] ksm-remove-dedicated-macro-ksm_flag_mask.patch removed from -mm tree

[akpm]

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@huawei.com>
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.
