Atish Patra	3ddb6d4df6	RISC-V: KVM: Rename the SBI_STA_SHMEM_DISABLE to a generic name ... SBI_STA_SHMEM_DISABLE is a macro to invoke disable shared memory commands. As this can be invoked from other SBI extension context as well, rename it to more generic name as SBI_SHMEM_DISABLE.

Andrew Jones	3752219b60	RISC-V: paravirt: Use correct restricted types ... __le32 and __le64 types should be used with le32_to_cpu() and le64_to_cpu(), as sparse helpfully points out.

Andrew Jones	17c8e9ac95	RISC-V: paravirt: steal_time should be static ... steal_time is not used outside paravirt.c, make it static, as sparse suggested.

Andrew Jones	fdf68acccf	RISC-V: paravirt: Implement steal-time support ... When the SBI STA extension exists we can use it to implement paravirt steal-time support. Fill in the empty pv-time functions with an SBI STA implementation and add the Kconfig knobs allowing it to be enabled.

Andrew Jones	323925ed6d	RISC-V: paravirt: Add skeleton for pv-time support ... Add the files and functions needed to support paravirt time on RISC-V. Also include the common code needed for the first application of pv-time, which is steal-time. In the next patches we'll complete the functions to fully enable steal-time support.
