Going forward, can you please make sure you send patch series as threads
(i.e. individual patches with Reply-to: referencing the cover letter)?

[XEN PATCH v1 00/15] x86: make cpu virtualization support configurable
This series aims to continue what Xenia started a year ago:
https://lore.kernel.org/xen-devel/20230213145751.1047236-1-burzalod...@gmail.com/
Here's an attempt to provide a means to render the cpu virtualization
technology support in Xen configurable.
Currently, irrespectively of the target platform, both AMD-V and Intel VT-x
drivers are built.
The series adds two new Kconfig controls, SVM and VMX, that can be
used to switch to a finer-grained configuration for a given platform, and
reduce dead code.
The code separation is done using the new config guards.
Since the initial RFC series felt rather welcomed, I took a courage naming
it v1 and continuing from there. New changes are:
v1:
* changed Kconfig options naming
* use IS_ENABLED() instead of #ifdef where possible
* move altp2m code apart from p2m & hide under VMX option
* introduce helper in cpu_has_vmx_* macros
* and address other comments from Jan

x86/p2m: guard altp2m init/teardown
x86/p2m: move altp2m-related code to separate file
x86/p2m: guard altp2m code with CONFIG_VMX option
x86/vpmu: separate amd/intel vPMU code
x86/vmx: introduce helper function for vmcs macro
Xenia Ragiadakou (9):

x86/oprofile: guard svm specific symbols with CONFIG_SVM
x86: wire cpu_has_{svm/vmx}_* to false when svm/vmx not enabled
x86/ioreq: guard VIO_realmode_completion with CONFIG_VMX
