[PATCH V5 3/8] MIPS: Ensure pmd_present() returns false after pmd_mknotpresent()

This patch is borrowed from ARM64 to ensure pmd_present() returns false after pmd_mknotpresent(). This is needed for THP.

[PATCH V5 2/8] MIPS: c-r4k: Add r4k_blast_scache_node for Loongson-3

by Huacai Chen

For multi-node Loongson-3 (NUMA configuration), r4k_blast_scache() can only flush Node-0's scache. So we add r4k_blast_scache_node() by using (CAC_BASE | (node_id << NODE_ADDRSPACE_SHIFT)) instead of CKSEG0 as the start address.

[PATCH 4.21 V3] blk-mq: not embed .mq_kobj and ctx->kobj into queue instance

by Ming Lei

Even though .mq_kobj, ctx->kobj and q->kobj share same lifetime from block layer's view, actually they don't because userspace may grab one kobject anytime via sysfs. This patch fixes the issue by the following approach: 1) introduce 'struct blk_mq_ctxs' for holding .mq_kobj and managing all ctxs 2) free all allocated ctxs and the 'blk_mq_ctxs' instance in release handler of .mq_kobj 3) grab one ref of .mq_kobj before initializing each ctx->kobj, so that .mq_kobj is always released after all ctxs are freed. This patch fixes kernel panic issue during booting when DEBUG_KOBJECT_RELEASE is enabled.

[PATCH 1/4] KVM: arm/arm64: vgic: Do not cond_resched_lock() with IRQs disabled

by Julien Thierry

To change the active state of an MMIO, halt is requested for all vcpus of the affected guest before modifying the IRQ state. This is done by calling cond_resched_lock() in vgic_mmio_change_active(). However interrupts are disabled at this point and running a vcpu cannot get rescheduled. Solve this by waiting for all vcpus to be halted after emmiting the halt request.
