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.

2020-07-10KVM: nVMX: fixes for preemption timer migrationPaolo Bonzini
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.

2020-07-10dmabuf: use spinlock to access dmabuf->nameCharan Teja Kalla
There exists a sleep-while-atomic bug while accessing the dmabuf->name under mutex in the dmabuffs_dname(). This is caused from the SELinux permissions checks on a process where it tries to validate the inherited files from fork() by traversing them through iterate_fd() (which traverse files under spin_lock) and call match_file(security/selinux/hooks.c) where the permission checks happen. This audit information is logged using dump_common_audit_data() where it calls d_path() to get the file path name. If the file check happen on the dmabuf's fd, then it ends up in ->dmabuffs_dname() and use mutex to access dmabuf->name. The flow will be like below: flush_unauthorized_files() iterate_fd() spin_lock() --> Start of the atomic section. match_file() file_has_perm() avc_has_perm() avc_audit() slow_avc_audit() common_lsm_audit() dump_common_audit_data() audit_log_d_path() d_path() dmabuffs_dname() mutex_lock()--> Sleep while atomic.

2020-07-09riscv: Avoid kgdb.h including gdb_xml.h to solve unused-const-variable warningVincent Chen
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.

It causes other architectures will encounter the "no previous prototype" warnings if the compile option has W=1.

2020-07-09net/mlx5e: Fix port buffers cell size valueEran Ben Elisha
Device unit for port buffers size, xoff_threshold and xon_threshold is cells. Fix a bug in driver where cell unit size was hard-coded to 128 bytes. This hard-coded value is buggy, as it is wrong for some hardware versions. Driver to read cell size from SBCAM register and translate bytes to cell units accordingly. In order to fix the bug, this patch exposes SBCAM (Shared buffer capabilities mask) layout and defines. If SBCAM.cap_cell_size is valid, use it for all bytes to cells calculations. If not valid, fallback to 128. Cell size do not change on the fly per device. Instead of issuing SBCAM access reg command every time such translation is needed, cache it in mlx5e_dcbx as part of mlx5e_dcbnl_initialize(). Pass dcbx.port_buff_cell_sz as a param to every function that needs bytes to cells translation. While fixing the bug, move MLX5E_BUFFER_CELL_SHIFT macro to en_dcbnl.c, as it is only used by that file.

When the capability is unset, read PTYS.ext_eth_proto_capability (always reliable). If PTYS.ext_eth_proto_capability is valid (has a non-zero value) conclude that the HCA supports 50G per lane.

Fix eeprom SFP query support by setting i2c_addr, offset and page number correctly. Unlike QSFP modules, SFP eeprom params are as follow: - i2c_addr is 0x50 for offset 0 - 255 and 0x51 for offset 256 - 511. - Page number is always zero. - Page offset is always relative to zero. As part of eeprom query, query the module ID (SFP / QSFP*) via helper function to set the params accordingly. In addition, change mlx5_qsfp_eeprom_page() input type to be u16 to avoid unnecessary casting.

2020-07-09Restore gcc check in mips asm/unroll.hCesar Eduardo Barros
While raising the gcc version requirement to 4.9, the compile-time check in the unroll macro was accidentally changed from being used on gcc and clang to being used on clang only. Restore the gcc check, changing it from "gcc >= 4.7" to "all gcc". [ We should probably remove this all entirely: if we remove the check for CLANG, then the check for GCC can go away.
