- Overhaul of the x86 EFI boot/runtime code

- Add the ability to disable DMA at the root port level in the EFI stub
- Get rid of RWX mappings in the EFI memory map and page tables, where possible
- Move the support code for the old EFI memory mapping style into its only user, the SGI UV1+ support code.
- plus misc fixes, updates, smaller cleanups.
... and due to interactions with the RWX changes, another round of PAT cleanups make a guest appearance via the EFI tree - with no side effects intended"

A pretty big release this time around, a lot of new drivers and both Morimoto-san and Takashi were doing subsystem wide updates as well:
- Further big refactorings from Morimoto-san simplifying the core interfaces and moving things to the component level. - Transition of drivers to managed buffer allocation and removal of redundant PCM ioctls. - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015 and RT1308.

Merge tag 'rds-odp-for-5.5' into rdma.git for-next
From https://git.kernel.org/pub/scm/linux/kernel/git/leon/linux-rdma
Leon Romanovsky says:
==================== Use ODP MRs for kernel ULPs
The following series extends MR creation routines to allow creation of user MRs through kernel ULPs as a proxy. The immediate use case is to allow RDS to work over FS-DAX, which requires ODP (on-demand-paging) MRs to be created and such MRs were not possible to create prior this series.
The first part of this patchset extends RDMA to have special verb ib_reg_user_mr(). The common use case that uses this function is a userspace application that allocates memory for HCA access but the responsibility to register the memory at the HCA is on an kernel ULP. This ULP acts as an agent for the userspace application.
The second part provides advise MR functionality for ULPs. This is integral part of ODP flows and used to trigger pagefaults in advance to prepare memory before running working set.
The third part is actual user of those in-kernel APIs. ====================
* tag 'rds-odp-for-5.5': net/rds: Use prefetch for On-Demand-Paging MR net/rds: Handle ODP mr registration/unregistration net/rds: Detect need of On-Demand-Paging memory registration RDMA/mlx5: Fix handling of IOVA != user_va in ODP paths IB/mlx5: Mask out unsupported ODP capabilities for kernel QPs RDMA/mlx5: Don't fake udata for kernel path IB/mlx5: Add ODP WQE handlers for kernel QPs IB/core: Add interface to advise_mr for kernel users IB/core: Introduce ib_reg_user_mr IB: Allow calls to ib_umem_get from kernel ULPs

We currently try to shrink a single zone when removing memory. We use the zone of the first page of the memory we are removing. If that memmap was never initialized (e.g., memory was never onlined), we will read garbage and can trigger kernel BUGs (due to a stale pointer):

Instead, shrink the zones when offlining memory or when onlining failed. Introduce and use remove_pfn_range_from_zone(() for that. We now properly shrink the zones, even if we have DIMMs whereby
- Some memory blocks fall into no zone (never onlined)
- Some memory blocks fall into multiple zones (offlined+re-onlined)
- Multiple memory blocks that fall into different zones
Drop the zone parameter (with a potential dubious value) from __remove_pages() and __remove_section().

mm, x86/mm: Untangle address space layout definitions from basic pgtable type definitions
- Untangle the somewhat incestous way of how VMALLOC_START is used all across the kernel, but is, on x86, defined deep inside one of the lowest level page table headers. It doesn't help that vmalloc.h only includes a single asm header:
#include <asm/page.h> /* pgprot_t */
So there was no existing cross-arch way to decouple address layout definitions from page.h details. I used this:
#ifndef VMALLOC_START # include <asm/vmalloc.h> #endif
This way every architecture that wants to simplify page.h can do so.
- Also on x86 we had a couple of LDT related inline functions that used the late-stage address space layout positions - but these could be uninlined without real trouble - the end result is cleaner this way as well.
