[PATCH v2 1/1] mm: pgtable: fix pte_swp_exclusive

Make pte_swp_exclusive return bool instead of int. This will better reflect how pte_swp_exclusive is actually used in the code. This fixes swap/swapoff problems on Alpha due pte_swp_exclusive not returning correct values when _PAGE_SWP_EXCLUSIVE bit resides in upper 32-bits of PTE (like on alpha).

[PATCH v2 0/1] mm: pgtable: fix pte_swp_exclusive

The first version of this patch intended to fix issues with swap memory on alpha, when swapoff fails to writeback exclusive swap pages and gets stuck in an infinite loop trying to do so. This problem appeared after commit a172d5128706028ac07b8db709728379ecc72f6e and as far as I know only affected t

[PATCH] mm/ioremap: Pass pgprot_t to ioremap_prot() instead of unsigned long

From: Ryan Roberts ioremap_prot() currently accepts pgprot_val parameter as an unsigned long, thus implicitly assuming that pgprot_val and pgprot_t could never be bigger than unsigned long. But this assumption soon will not be true on arm64 when using D128 pgtables. In 128 bit page table configur
