Here's the main documentation changes for 5.5:
- Various kerneldoc script enhancements. - More RST conversions; those are slowing down as we run out of things to convert, but we're a ways from done still. - Dan's "maintainer profile entry" work landed at last. Now we just need to get maintainers to fill in the profiles... - A reworking of the parallel build setup to work better with a variety of systems (and to not take over huge systems entirely in particular). - The MAINTAINERS file is now converted to RST during the build. Hopefully nobody ever tries to print this thing, or they will need to load a lot of paper. - A script and documentation making it easy for maintainers to add Link: tags at commit time.

Documentation/admin-guide/cgroup-v2.rst: document why inactive_X + active_X may not equal X
This has confused a significant number of people using cgroups inside Facebook, and some of those outside as well judging by posts like this[0] (although it's not a problem unique to cgroup v2). If shmem handling in particular becomes more coherent at some point in the future -- although that seems unlikely now -- we can change the wording here.

Driver core patches for 5.5-rc1
Here is the "big" set of driver core patches for 5.5-rc1 There's a few minor cleanups and fixes in here, but the majority of the patches in here fall into two buckets: - debugfs api cleanups and fixes - driver core device link support for boot dependancy issues The debugfs api cleanups are working to slowly refactor the debugfs apis so that it is even harder to use incorrectly. That work has been happening for the past few kernel releases and will continue over time, it's a long-term project/goal The driver core device link support missed 5.4 by just a bit, so it's been sitting and baking for many months now. It's from Saravana Kannan to help resolve the problems that DT-based systems have at boot time with dependancy graphs and kernel modules. Turns out that no one has actually tried to build a generic arm64 kernel with loads of modules and have it "just work" for a variety of platforms (like a distro kernel) The big problem turned out to be a lack of depandancy information between different areas of DT entries, and the work here resolves that problem and now allows devices to boot properly, and quicker than a monolith kernel. All of these patches have been in linux-next for a long time with no reported issues.

arm64 updates for 5.5:
- On ARMv8 CPUs without hardware updates of the access flag, avoid failing cow_user_page() on PFN mappings if the pte is old. The patches introduce an arch_faults_on_old_pte() macro, defined as false on x86. When true, cow_user_page() makes the pte young before attempting __copy_from_user_inatomic(). - Covert the synchronous exception handling paths in arch/arm64/kernel/entry.S to C. - FTRACE_WITH_REGS support for arm64. - ZONE_DMA re-introduced on arm64 to support Raspberry Pi 4 - Several kselftest cases specific to arm64, together with a MAINTAINERS update for these files (moved to the ARM64 PORT entry). - Workaround for a Neoverse-N1 erratum where the CPU may fetch stale instructions under certain conditions. - Workaround for Cortex-A57 and A72 errata where the CPU may speculatively execute an AT instruction and associate a VMID with the wrong guest page tables (corrupting the TLB). - Perf updates for arm64: additional PMU topologies on HiSilicon platforms, support for CCN-512 interconnect, AXI ID filtering in the IMX8 DDR PMU, support for the CCPI2 uncore PMU in ThunderX2. - GICv3 optimisation to avoid a heavy barrier when accessing the ICC_PMR_EL1 register. - ELF HWCAP documentation updates and clean-up. - SMC calling convention conduit code clean-up. - KASLR diagnostics printed during boot - NVIDIA Carmel CPU added to the KPTI whitelist - Some arm64 mm clean-ups: use generic free_initrd_mem(), remove stale macro, simplify calculation in __create_pgd_mapping(), typos. - Kconfig clean-ups: CMDLINE_FORCE to depend on CMDLINE, choice for endinanness to help with allmodconfig. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAl3YJswACgkQa9axLQDI XvFwYg//aTGhNLew3ADgW2TYal7LyqetRROixPBrzqHLu2A8No1+QxHMaKxpZVyf pt25tABuLtPHql3qBzE0ltmfbLVsPj/3hULo404EJb9HLRfUnVGn7gcPkc+p4YAr IYkYPXJbk6OlJ84vI+4vXmDEF12bWCqamC9qZ+h99qTpMjFXFO17DSJ7xQ8Xic3A HHgCh4uA7gpTVOhLxaS6KIw+AZNYwvQxLXch2+wj6agbGX79uw9BeMhqVXdkPq8B RTDJpOdS970WOT4cHWOkmXwsqqGRqgsgyu+bRUJ0U72+0y6MX0qSHIUnVYGmNc5q Dtox4rryYLvkv/hbpkvjgVhv98q3J1mXt/CalChWB5dG4YwhJKN2jMiYuoAvB3WS 6dR7Dfupgai9gq1uoKgBayS2O6iFLSa4g58vt3EqUBqmM7W7viGFPdLbuVio4ycn CNF2xZ8MZR6Wrh1JfggO7Hc11EJdSqESYfHO6V/pYB4pdpnqJLDoriYHXU7RsZrc HvnrIvQWKMwNbqBvpNbWvK5mpBMMX2pEienA3wOqKNH7MbepVsG+npOZTVTtl9tN FL0ePb/mKJu/2+gW8ntiqYn7EzjKprRmknOiT2FjWWo0PxgJ8lumefuhGZZbaOWt /aTAeD7qKd/UXLKGHF/9v3q4GEYUdCFOXP94szWVPyLv+D9h8L8= =TPL9 -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: "Apart from the arm64-specific bits (core arch and perf, new arm64 selftests), it touches the generic cow_user_page() (reviewed by Kirill) together with a macro for x86 to preserve the existing behaviour on this architecture.

block: add iostat counters for flush requests
Requests that triggers flushing volatile writeback cache to disk (barriers) have significant effect to overall performance. Block layer has sophisticated engine for combining several flush requests into one. But there is no statistics for actual flushes executed by disk. Requests which trigger flushes usually are barriers - zero-size writes. This patch adds two iostat counters into /sys/class/block/$dev/stat and /proc/diskstats - count of completed flush requests and their total time.

x86/speculation: Fix incorrect MDS/TAA mitigation status
For MDS vulnerable processors with TSX support, enabling either MDS or
TAA mitigations will enable the use of VERW to flush internal processor
buffers at the right code path. IOW, they are either both mitigated
or both not. However, if the command line options are inconsistent,
the vulnerabilites sysfs files may not report the mitigation status
correctly.
For example, with only the "mds=off" option:
vulnerabilities/mds:Vulnerable; SMT vulnerable
vulnerabilities/tsx_async_abort:Mitigation: Clear CPU buffers; SMT vulnerable
The mds vulnerabilities file has wrong status in this case. Similarly,
the taa vulnerability file will be wrong with mds mitigation on, but
taa off.
Change taa_select_mitigation() to sync up the two mitigation status
and have them turned off if both "mds=off" and "tsx_async_abort=off"
are present.
Update documentation to emphasize the fact that both "mds=off" and
"tsx_async_abort=off" have to be specified together for processors that
are affected by both TAA and MDS to be effective.
[ bp: Massage and add kernel-parameters.txt change too. ]

dm integrity: fix excessive alignment of metadata runs
Metadata runs are supposed to be aligned on 4k boundary (so that they work efficiently with disks with 4k sectors). However, there was a programming bug that makes them aligned on 128k boundary instead. The unused space is wasted. Fix this bug by providing a proper 4k alignment. In order to keep existing volumes working, we introduce a new flag SB_FLAG_FIXED_PADDING - when the flag is clear, we calculate the padding the old way. In order to make sure that the old version cannot mount the volume created by the new version, we increase superblock version to 4. Also in order to not break with old integritysetup, we fix alignment only if the parameter "fix_padding" is present when formatting the device.

x86/efi: Add efi_fake_mem support for EFI_MEMORY_SP
Given that EFI_MEMORY_SP is platform BIOS policy decision for marking memory ranges as "reserved for a specific purpose" there will inevitably be scenarios where the BIOS omits the attribute in situations where it is desired. Unlike other attributes if the OS wants to reserve this memory from the kernel the reservation needs to happen early in init. So early, in fact, that it needs to happen before e820__memblock_setup() which is a pre-requisite for efi_fake_memmap() that wants to allocate memory for the updated table. Introduce an x86 specific efi_fake_memmap_early() that can search for attempts to set EFI_MEMORY_SP via efi_fake_mem and update the e820 table accordingly. The KASLR code that scans the command line looking for user-directed memory reservations also needs to be updated to consider "efi_fake_mem=nn@ss:0x40000" requests.

efi: Common enable/disable infrastructure for EFI soft reservation
UEFI 2.8 defines an EFI_MEMORY_SP attribute bit to augment the interpretation of the EFI Memory Types as "reserved for a specific purpose". The proposed Linux behavior for specific purpose memory is that it is reserved for direct-access (device-dax) by default and not available for any kernel usage, not even as an OOM fallback. Later, through udev scripts or another init mechanism, these device-dax claimed ranges can be reconfigured and hot-added to the available System-RAM with a unique node identifier. This device-dax management scheme implements "soft" in the "soft reserved" designation by allowing some or all of the reservation to be recovered as typical memory. This policy can be disabled at compile-time with CONFIG_EFI_SOFT_RESERVE=n, or runtime with efi=nosoftreserve. As for this patch, define the common helpers to determine if the EFI_MEMORY_SP attribute should be honored. The determination needs to be made early to prevent the kernel from being loaded into soft-reserved memory, or otherwise allowing early allocations to land there. Follow-on changes are needed per architecture to leverage these helpers in their respective mem-init paths.

dm raid: to ensure resynchronization, perform raid set grow in preresume
This fixes a flaw causing raid set extensions not to be synchronized in case the MD bitmap resize required additional pages to be allocated. Also share resize code in the raid constructor between new size changes and those occuring during recovery. Bump the target version to define the change and document it in Documentation/admin-guide/device-mapper/dm-raid.rst.

kvm: x86: mmu: Recovery of shattered NX large pages
The page table pages corresponding to broken down large pages are zapped in FIFO order, so that the large page can potentially be recovered, if it is not longer being used for execution. This removes the performance penalty for walking deeper EPT page tables. By default, one large page will last about one hour once the guest reaches a steady state.

kvm: mmu: ITLB_MULTIHIT mitigation
With some Intel processors, putting the same virtual address in the TLB as both a 4 KiB and 2 MiB page can confuse the instruction fetch unit and cause the processor to issue a machine check resulting in a CPU lockup. Unfortunately when EPT page tables use huge pages, it is possible for a malicious guest to cause this situation. Add a knob to mark huge pages as non-executable. When the nx_huge_pages parameter is enabled (and we are using EPT), all huge pages are marked as NX. If the guest attempts to execute in one of those pages, the page is broken down into 4K pages, which are then marked executable. This is not an issue for shadow paging (except nested EPT), because then the host is in control of TLB flushes and the problematic situation cannot happen. With nested EPT, again the nested guest can cause problems shadow and direct EPT is treated in the same way.
