As result, all the ugly bit checks are replaced # by simple evaluations of the required bit fields. # # - Improve handling of some weird scenarios between service element (SE) # host and SE guest with adjunct-processor (AP) pass-through support. # # - Change local_ctl_set_bit() and local_ctl_clear_bit() so they return # the previous value of the to be changed control register. This is # useful if a bit is only changed temporarily and the previous content # needs to be restored. # # - The kernel starts with machine checks disabled and is expected to # enable it once trap_init() is called. However the implementation # allows machine checks early. Consistently enable it in trap_init() # only. # # - local_mcck_disable() and local_mcck_enable() assume that machine # checks are always enabled. Instead implement and use # local_mcck_save() and local_mcck_restore() to disable machine checks # and restore the previous state. # # - Modification of floating point control (FPC) register of a traced # process using ptrace interface may lead to corruption of the FPC # register of the tracing process. Fix this. # # - kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point # control (FPC) register in vCPU, but may lead to corruption of the FPC # register of the host process. Fix this. # # - Use READ_ONCE() to read a vCPU floating point register value from the # memory mapped area. This avoids that, depending on code generation, a # different value is tested for validity than the one that is used. # # - Get rid of test_fp_ctl(), since it is quite subtle to use it # correctly. Instead copy a new floating point control register value # into its save area and test the validity of the new value when # loading it. # # - Remove superfluous save_fpu_regs() call. # # - Remove s390 support for ARCH_WANTS_DYNAMIC_TASK_STRUCT. All machines # provide the vector facility since many years and the need to make the # task structure size dependent on the vector facility does not exist. # # - Remove the "novx" kernel command line option, as the vector code runs # without any problems since many years. # # - Add the vector facility to the z13 architecture level set (ALS). All # hypervisors support the vector facility since many years. This allows # compile time optimizations of the kernel. # # - Get rid of MACHINE_HAS_VX and replace it with cpu_has_vx(). As # result, the compiled code will have less runtime checks and less # code. # # - Convert pgste_get_lock() and pgste_set_unlock() ASM inlines to C. # # - Convert the struct subchannel spinlock from pointer to member. # # * tag 's390-6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (24 commits) # Revert "s390: update defconfigs" # s390/cio: make sch->lock spinlock pointer a member # s390: update defconfigs # s390/mm: convert pgste locking functions to C # s390/fpu: get rid of MACHINE_HAS_VX # s390/als: add vector facility to z13 architecture level set # s390/fpu: remove "novx" option # s390/fpu: remove ARCH_WANTS_DYNAMIC_TASK_STRUCT support # KVM: s390: remove superfluous save_fpu_regs() call # s390/fpu: get rid of test_fp_ctl() # KVM: s390: use READ_ONCE() to read fpc register value # KVM: s390: fix setting of fpc register # s390/ptrace: handle setting of fpc register correctly # s390/nmi: implement and use local_mcck_save() / local_mcck_restore() # s390/nmi: consistently enable machine checks in trap_init() # s390/ctlreg: return old register contents when changing bits # s390/ap: handle outband SE bind state change # s390/ap: store TAPQ hwinfo in struct ap_card # s390/vfio-ap: fix sysfs status attribute for AP queue devices # s390/vfio-ap: improve reaction to response code 07 from PQAP(AQIC) command # ... # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 de927f6c0b07d9e698416c5b287c521b07694cac # make -s -j 24 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux- se7619_defconfig # < make -s -j 24 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 24 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 24 ARCH=sh O=/kisskb/build/linus_se7619_defconfig_sh4-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h :1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/init.c:99:29: warning: no previous prototype for 'l2_cache_init' [-Wmissing-prototypes] 99 | void __attribute__ ((weak)) l2_cache_init(void) | ^~~~~~~~~~~~~ /kisskb/src/arch/sh/mm/cache-sh2.c:85:13: warning: no previous prototype for 'sh2_cache_init' [-Wmissing-prototypes] 85 | void __init sh2_cache_init(void) | ^~~~~~~~~~~~~~ /kisskb/src/arch/sh/mm/nommu.c:76:13: warning: no previous prototype for 'kmap_coherent_init' [-Wmissing-prototypes] 76 | void __init kmap_coherent_init(void) | ^~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sh/mm/nommu.c:80:7: warning: no previous prototype for 'kmap_coherent' [-Wmissing-prototypes] 80 | void *kmap_coherent(struct page *page, unsigned long addr) | ^~~~~~~~~~~~~ /kisskb/src/arch/sh/mm/nommu.c:86:6: warning: no previous prototype for 'kunmap_coherent' [-Wmissing-prototypes] 86 | void kunmap_coherent(void *kvaddr) | ^~~~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/return_address.c:49:7: warning: no previous prototype for 'return_address' [-Wmissing-prototypes] 49 | void *return_address(unsigned int depth) | ^~~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/sys_sh.c:58:16: warning: no previous prototype for 'sys_cacheflush' [-Wmissing-prototypes] 58 | asmlinkage int sys_cacheflush(unsigned long addr, unsigned long len, int op) | ^~~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/traps_32.c:735:6: warning: no previous prototype for 'per_cpu_trap_init' [-Wmissing-prototypes] 735 | void per_cpu_trap_init(void) | ^~~~~~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/hw_breakpoint.c:135:5: warning: no previous prototype for 'arch_bp_generic_fields' [-Wmissing-prototypes] 135 | int arch_bp_generic_fields(int sh_len, int sh_type, | ^~~~~~~~~~~~~~~~~~~~~~ during RTL pass: final In file included from /kisskb/src/fs/namespace.c:11: /kisskb/src/fs/namespace.c: In function '__se_sys_listmount': /kisskb/src/include/linux/syscalls.h:258:9: internal compiler error: in change_address_1, at emit-rtl.c:2275 258 | } \ | ^ /kisskb/src/include/linux/syscalls.h:233:9: note: in expansion of macro '__SYSCALL_DEFINEx' 233 | __SYSCALL_DEFINEx(x, sname, __VA_ARGS__) | ^~~~~~~~~~~~~~~~~ /kisskb/src/include/linux/syscalls.h:225:36: note: in expansion of macro 'SYSCALL_DEFINEx' 225 | #define SYSCALL_DEFINE4(name, ...)
