Merge tag 'x86_urgent_for_v6.4_rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fix from Borislav Petkov:
- Set up the kernel CS earlier in the boot process in case EFI boots
the kernel after bypassing the decompressor and the CS descriptor
used ends up being the EFI one which is not mapped in the identity
page table, leading to early SEV/SNP guest communication exceptions
resulting in the guest crashing

Optionally, build kernel with PAGE_TABLE_CHECK_ENFORCED in order to have page
table support without extra kernel parameter.
+
+Implementation notes
+====================
+
+We specifically decided not to use VMA information in order to avoid relying on
+MM states (except for limited "struct page" info). The page table check is a
+separate from Linux-MM state machine that verifies that the user accessible
+pages are not falsely shared.
+
+PAGE_TABLE_CHECK depends on EXCLUSIVE_SYSTEM_RAM. The reason is that without
+EXCLUSIVE_SYSTEM_RAM, users are allowed to map arbitrary physical memory
+regions into the userspace via /dev/mem. At the same time, pages may change
+their properties (e.g., from anonymous pages to named pages) while they are
+still being mapped in the userspace, leading to "corruption" detected by the
+page table check.
+
+Even with EXCLUSIVE_SYSTEM_RAM, I/O pages may be still allowed to be mapped via
+/dev/mem. However, these pages are always considered as named pages, so they
+won't break the logic used in the page table check.

Completion" sesction below.
+The consumer can provide a NUL-terminated hostname in the @ta_peername
+field that is sent as part of ClientHello. If no peername is provided,
+the DNS hostname associated with the server's IP address is used instead.

The consumer can fill in the @ta_timeout_ms field to force the servicing
handshake agent to exit after a number of milliseconds. This enables the
socket to be fully closed once both the kernel and the handshake agent

Updating patch status
~~~~~~~~~~~~~~~~~~~~~
-It may be tempting to help the maintainers and update the state of your
-own patches when you post a new version or spot a bug. Please **do not**
-do that.
-Interfering with the patch status on patchwork will only cause confusion. Leave
-it to the maintainer to figure out what is the most recent and current
-version that should be applied. If there is any doubt, the maintainer
-will reply and ask what should be done.
+Contributors and reviewers do not have the permissions to update patch
+state directly in patchwork. Patchwork doesn't expose much information
+about the history of the state of patches, therefore having multiple
+people update the state leads to confusion.
+
+Instead of delegating patchwork permissions netdev uses a simple mail
+bot which looks for special commands/lines within the emails sent to
+the mailing list. For example to mark a series as Changes Requested
+one needs to send the following line anywhere in the email thread::
+
+ pw-bot: changes-requested
+
+As a result the bot will set the entire series to Changes Requested.
+This may be useful when author discovers a bug in their own series
+and wants to prevent it from getting applied.
+
+The use of the bot is entirely optional, if in doubt ignore its existence
+completely. Maintainers will classify and update the state of the patches
+themselves. No email should ever be sent to the list with the main purpose
+of communicating with the bot, the bot commands should be seen as metadata.
+
+The use of the bot is restricted to authors of the patches (the ``From:``
+header on patch submission and command must match!), maintainers themselves
+and a handful of senior reviewers. Bot records its activity here:
+
+ https://patchwork.hopto.org/pw-bot.html
