Pull misc x86 fixes and updates from Ingo Molnar: - Fix a large number of x86 Kconfig dependency and help text accuracy bugs/problems, by Mateusz Jończyk and David Heideberg - Fix a VM_PAT interaction with fork() crash. This also touches core kernel code - Fix an ORC unwinder bug for interrupt entries - Fixes and cleanups - Fix an AMD microcode loader bug that can promote verification failures into success - Add early-printk support for MMIO based UARTs on an x86 board that had no other serial debugging facility and also experienced early boot crashes * tag 'x86-urgent-2025-03-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/microcode/AMD: Fix __apply_microcode_amd()'s return value x86/mm/pat: Fix VM_PAT handling when fork() fails in copy_page_range() x86/fpu: Update the outdated comment above fpstate_init_user() x86/early_printk: Add support for MMIO-based UARTs x86/dumpstack: Fix inaccurate unwinding from exception stacks due to misplaced assignment x86/entry: Fix ORC unwinder for PUSH_REGS with save_ret=1 x86/Kconfig: Fix lists in X86_EXTENDED_PLATFORM help text x86/Kconfig: Correct X86_X2APIC help text x86/speculation: Remove the extra #ifdef around CALL_NOSPEC x86/Kconfig: Document release year of glibc 2.3.3 x86/Kconfig: Make CONFIG_PCI_CNB20LE_QUIRK depend on X86_32 x86/Kconfig: Document CONFIG_PCI_MMCONFIG x86/Kconfig: Update lists in X86_EXTENDED_PLATFORM x86/Kconfig: Move all X86_EXTENDED_PLATFORM options together x86/Kconfig: Always enable ARCH_SPARSEMEM_ENABLE x86/Kconfig: Enable X86_X2APIC by default and improve help text
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
