<torvalds@linux-foundation.org> # Date: Wed Jan 10 18:18:20 2024 -0800 # # Merge tag 's390-6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux # # Pull s390 updates from Alexander Gordeev: # # - Add machine variable capacity information to /proc/sysinfo. # # - Limit the waste of page tables and always align vmalloc area size and # base address on segment boundary. # # - Fix a memory leak when an attempt to register interruption sub class # (ISC) for the adjunct-processor (AP) guest failed. # # - Reset response code AP_RESPONSE_INVALID_GISA to understandable by # guest AP_RESPONSE_INVALID_ADDRESS in response to a failed # interruption sub class (ISC) registration attempt. # # - Improve reaction to adjunct-processor (AP) # AP_RESPONSE_OTHERWISE_CHANGED response code when enabling interrupts # on behalf of a guest. # # - Fix incorrect sysfs 'status' attribute of adjunct-processor (AP) # queue device bound to the vfio_ap device driver when the mediated # device is attached to a guest, but the queue device is not passed # through. # # - Rework struct ap_card to hold the whole adjunct-processor (AP) card # hardware information. 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
