[PATCH v8 0/8] KVMTOOL RISC-V Support

[Anup Patel]

This series adds RISC-V support for KVMTOOL and it is based on
the v10 of KVM RISC-V series. The KVM RISC-V patches are not yet
merged in Linux kernel but it will be good to get early review
for KVMTOOL RISC-V support.

The KVMTOOL RISC-V patches can be found in riscv_master branch at:
https//github.com/kvm-riscv/kvmtool.git

The KVM RISC-V patches can be found in riscv_kvm_master branch at:
https//github.com/kvm-riscv/linux.git

 - Rebased on recent commit 117d64953228afa90b52f6e1b4873770643ffdc9
 - Sync-up headers with latest KVM RISC-V v17 series which is based
   on Linux-5.12-rc5

Changes since v5:
 - Sync-up headers with latest KVM RISC-V v16 series which is based
   on Linux-5.11-rc3

Changes since v4:
 - Rebased on recent commit 90b2d3adadf218dfc6bdfdfcefe269843360223c
 - Sync-up headers with latest KVM RISC-V v15 series which is based

Changes since v3:
 - Rebased on recent commit 351d931f496aeb2e97b8daa44c943d8b59351d07
 - Improved kvm_cpu__show_registers() implementation

Changes since v2:
 - Support compiling KVMTOOL for both RV32 and RV64 systems using
   a multilib toolchain
 - Fix kvm_cpu__arch_init() for RV32 system

Changes since v1:
 - Use linux/sizes.h in kvm/kvm-arch.h
 - Added comment in kvm/kvm-arch.h about why PCI config space is 256M
 - Remove forward declaration of "struct kvm" from kvm/kvm-cpu-arch.h
 - Fixed placement of DTB and INITRD in guest RAM
 - Use __riscv_xlen instead of sizeof(unsigned long) in __kvm_reg_id()
