[RFC PATCH] scsi: ufs: Add specific callback for setting DMA mask

Currently DMA mask for UFS HCI is set by reading CAP register's [64AS] bit. Some HCI controller like Exynos support 36-bit bus address. This works perfectly fine with DMA mask set as 64 in case there is no IOMMU attached to HCI. In case if HCI is behind an IOMMU, setting DMA mask as 64 bit won't

[PATCH 07/12] efi: Use efi_mm in x86 as well as ARM

From: Sai Praneeth Presently, only ARM uses mm_struct to manage efi page tables and efi runtime region mappings. As this is the preferred approach, let's make this data structure common across architectures. Specially, for x86, using this data structure improves
