[SRU][N:linux, N:linux-azure][PATCH 0/1] Fix failure to build TDX module

[John Cabaj]

BugLink: https://bugs.launchpad.net/bugs/2126698

SRU Justification

[Impact]

* Upstream 9f98a4f4e721: "x86/tdx: Fix arch_safe_halt() execution for TDX VMs" added irq.safe_halt and irq.halt calls outside of the CONFIG_PARAVIRT_XXL preprocessor directive of which the definitions occur in arch/x86/include/asm/paravirt_types.h, leading to a compilation error

[Fix]

* Simple backport of 22cc5ca5de52: "x86/paravirt: Move halt paravirt calls under CONFIG_PARAVIRT" upstream

[Test Plan]

* Compile tested

[Regression potential]

* Possible regressions could result in unexpected behavior of Xen guests, though patch has been upstream for around 8 months.
