x86/msr: Add explicit includes of

2025-05-02T08:23:47Z

For historic reasons there are some TSC-related functions in the header, even though there's an header. To facilitate the relocation of rdtsc{,_ordered}() from to and to eventually eliminate the inclusion of in , add an explicit dependency to the source files that reference definitions from .

module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

thermal: intel: intel_tcc_cooling: Use a model-specific bitmask for TCC offset

2024-06-21T12:52:12Z

The TCC offset field in the register MSR_TEMPERATURE_TARGET is not architectural. The TCC library provides a model-specific bitmask. Use it to determine the maximum TCC offset.
