mips: Remove compiler check in unroll macro

2020-07-10T22:42:06Z

CONFIG_CC_IS_GCC is undefined when Clang is used, which breaks the build (see our Travis link below). Clang 8 was chosen as a minimum version for this check because there were some improvements around __builtin_constant_p in that release. In reality, MIPS was not even buildable until clang 9 so that check was not technically necessary. Just remove all compiler checks and just assume that we have a working compiler. Fixes: d4e60453266b ("Restore gcc check in mips asm/unroll.h") Link: https://travis-ci.com/github/ClangBuiltLinux/continuous-integration/jobs/359642821 Signed-off-by: Nathan Chancellor Signed-off-by: Linus Torvalds

KVM: MIPS: Fix build errors for 32bit kernel

Commit dc6d95b153e78ed70b1b2c04a ("KVM: MIPS: Add more MMIO load/store instructions emulation") introduced some 64bit load/store instructions emulation which are unavailable on 32bit platform, and it causes build errors: arch/mips/kvm/emulate.c: In function 'kvm_mips_emulate_store': arch/mips/kvm/emulate.c:1734:6: error: right shift count >= width of type [-Werror] ((vcpu->arch.gprs[rt] >> 56) & 0xff); ^ arch/mips/kvm/emulate.c:1738:6: error: right shift count >= width of type [-Werror] ((vcpu->arch.gprs[rt] >> 48) & 0xffff); ^ arch/mips/kvm/emulate.c:1742:6: error: right shift count >= width of type [-Werror] ((vcpu->arch.gprs[rt] >> 40) & 0xffffff); ^ arch/mips/kvm/emulate.c:1746:6: error: right shift count >= width of type [-Werror] ((vcpu->arch.gprs[rt] >> 32) & 0xffffffff); ^ arch/mips/kvm/emulate.c:1796:6: error: left shift count >= width of type [-Werror] (vcpu->arch.gprs[rt] << 32); ^ arch/mips/kvm/emulate.c:1800:6: error: left shift count >= width of type [-Werror] (vcpu->arch.gprs[rt] << 40); ^ arch/mips/kvm/emulate.c:1804:6: error: left shift count >= width of type [-Werror] (vcpu->arch.gprs[rt] << 48); ^ arch/mips/kvm/emulate.c:1808:6: error: left shift count >= width of type [-Werror] (vcpu->arch.gprs[rt] << 56); ^ cc1: all warnings being treated as errors make[3]: *** [arch/mips/kvm/emulate.o] Error 1 So, use #if defined(CONFIG_64BIT) && defined(CONFIG_KVM_MIPS_VZ) to guard the 64bit load/store instructions emulation.

KVM: nVMX: fixes for preemption timer migration

2020-07-10T10:15:36Z

Commit 850448f35aaf ("KVM: nVMX: Fix VMX preemption timer migration", 2020-06-01) accidentally broke nVMX live migration from older version by changing the userspace ABI. Restore it and, while at it, ensure that vmx->nested.has_preemption_timer_deadline is always initialized according to the KVM_STATE_VMX_PREEMPTION_TIMER_DEADLINE flag.

riscv: Avoid kgdb.h including gdb_xml.h to solve unused-const-variable warning

2020-07-10T03:12:28Z

The constant arrays in gdb_xml.h are only used in arch/riscv/kernel/kgdb.c, but other c files may include the gdb_xml.h indirectly via including the kgdb.h. Hence, It will cause many unused-const-variable warnings. This patch makes the kgdb.h not to include the gdb_xml.h to solve this problem. Signed-off-by: Vincent Chen Signed-off-by: Palmer Dabbelt
