ata: libata: Set __ATA_BASE_SHT max_sectors

2022-08-20T16:29:50Z

Commit 0568e6122574 ("ata: libata-scsi: cap ata_device->max_sectors according to shost->max_sectors") inadvertently capped the max_sectors value for some SATA disks to a value which is lower than we would want. For a device which supports LBA48, we would previously have request queue max_sectors_kb and max_hw_sectors_kb values of 1280 and 32767 respectively. For AHCI controllers, the value chosen for shost max sectors comes from the minimum of the SCSI host default max sectors in SCSI_DEFAULT_MAX_SECTORS (1024) and the shost DMA device mapping limit. This means that we would now set the max_sectors_kb and max_hw_sectors_kb values for a disk which supports LBA48 at 512, ignoring DMA mapping limit. As report by Oliver at [0], this caused a performance regression. Fix by picking a large enough max sectors value for ATA host controllers such that we don't needlessly reduce max_sectors_kb for LBA48 disks.

KVM: Rename mmu_notifier_* to mmu_invalidate_*

2022-08-19T08:05:41Z

The motivation of this renaming is to make these variables and related helper functions less mmu_notifier bound and can also be used for non mmu_notifier based page invalidation. mmu_invalidate_* was chosen to better describe the purpose of 'invalidating' a page that those variables are used for. - mmu_notifier_seq/range_start/range_end are renamed to mmu_invalidate_seq/range_start/range_end. - mmu_notifier_retry{_hva} helper functions are renamed to mmu_invalidate_retry{_hva}. - mmu_notifier_count is renamed to mmu_invalidate_in_progress to avoid confusion with mn_active_invalidate_count. - While here, also update kvm_inc/dec_notifier_count() to kvm_mmu_invalidate_begin/end() to match the change for mmu_notifier_count. No functional change intended. Signed-off-by: Chao Peng Message-Id: <20220816125322.1110439-3-chao.p.peng@linux.intel.com> Signed-off-by: Paolo Bonzini

KVM: Rename KVM_PRIVATE_MEM_SLOTS to KVM_INTERNAL_MEM_SLOTS

2022-08-19T08:05:40Z

KVM_INTERNAL_MEM_SLOTS better reflects the fact those slots are KVM internally used (invisible to userspace) and avoids confusion to future private slots that can have different meaning.

net: mscc: ocelot: keep ocelot_stat_layout by reg address, not offset

2022-08-18T04:58:32Z

With so many counter addresses recently discovered as being wrong, it is desirable to at least have a central database of information, rather than two: one through the SYS_COUNT_* registers (used for ndo_get_stats64), and the other through the offset field of struct ocelot_stat_layout elements (used for ethtool -S). The strategy will be to keep the SYS_COUNT_* definitions as the single source of truth, but for that we need to expand our current definitions to cover all registers. Then we need to convert the ocelot region creation logic, and stats worker, to the read semantics imposed by going through SYS_COUNT_* absolute register addresses, rather than offsets of 32-bit words relative to SYS_COUNT_RX_OCTETS (which should have been SYS_CNT, by the way).
