commit 6890cb1ace350b4386c8aee1343dc3b3ddd214da upstream. MKTME repurposes the high bit of physical address to key id for encryption key and, even though MAXPHYADDR in CPUID[0x80000008] remains the same, the valid bits in the MTRR mask register are based on the reduced number of physical address bits. detect_tme() in arch/x86/kernel/cpu/intel.c detects TME and subtracts it from the total usable physical bits, but it is called too late. Move the call to early_init_intel() so that it is called in setup_arch(), before MTRRs are setup. This fixes boot on TDX-enabled systems, which until now only worked with "disable_mtrr_cleanup". Without the patch, the values written to the MTRRs mask registers were 52-bit wide (e.g. 0x000fffff_80000800) and the writes failed; with the patch, the values are 46-bit wide, which matches the reduced MAXPHYADDR that is shown in /proc/cpuinfo.

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 Restructured Text 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.
