ppc: Enable 2nd DAWR support on Power10

This series enables 2nd DAWR support on p10 qemu guest. 2nd DAWR is new watchpoint added in Power10 processor. Kernel/kvm patches are already in[1]. Patches apply fine on qemu/master branch (9e2e9fe3df9f). v1: https://lore.kernel.org/r/20200723104220.314671-1-ravi.bangoria@linux.ibm.com [Apologies for long gap] v1->v2: - Introduce machine capability cap-dawr1 to enable/disable the feature. By default, 2nd DAWR is OFF for guests even when host kvm supports it. User has to manually enable it with -machine cap-dawr1=on if he wishes to use it. - Split the header file changes into separate patch. (Sync headers from v5.12-rc3) [1] https://git.kernel.org/torvalds/c/bd1de1a0e6eff Ravi Bangoria (3): Linux headers: update from 5.12-rc3 ppc: Rename current DAWR macros and variables ppc: Enable 2nd DAWR support on p10 hw/ppc/spapr.c | 34 ++++++++++ hw/ppc/spapr_caps.c | 32 +++++++++ include/hw/ppc/spapr.h | 8 ++- include/standard-headers/drm/drm_fourcc.h | 23 ++++++- include/standard-headers/linux/input.h | 2 +- include/standard-headers/rdma/vmw_pvrdma-abi.h | 7 ++ linux-headers/asm-generic/unistd.h | 4 +- linux-headers/asm-mips/unistd_n32.h | 1 + linux-headers/asm-mips/unistd_n64.h | 1 + linux-headers/asm-mips/unistd_o32.h | 1 + linux-headers/asm-powerpc/kvm.h | 2 + linux-headers/asm-powerpc/unistd_32.h | 1 + linux-headers/asm-powerpc/unistd_64.h | 1 + linux-headers/asm-s390/unistd_32.h | 1 + linux-headers/asm-s390/unistd_64.h | 1 + linux-headers/asm-x86/kvm.h | 1 + linux-headers/asm-x86/unistd_32.h | 1 + linux-headers/asm-x86/unistd_64.h | 1 + linux-headers/asm-x86/unistd_x32.h | 1 + linux-headers/linux/kvm.h | 89 ++++++++++++++++++++++++++ linux-headers/linux/vfio.h | 27 ++++++++ target/ppc/cpu.h | 6 +- target/ppc/kvm.c | 12 ++++ target/ppc/kvm_ppc.h | 7 ++ target/ppc/translate_init.c.inc | 21 +++++- 25 files changed, 274 insertions(+), 11 deletions(-)
