The first_index/last_index parameters in zap_details are actually only used in
unmap_mapping_range_tree(). At the meantime, this function is only called by
unmap_mapping_pages() once. Instead of passing these two variables through the

Instead of trying to introduce one variable for every new zap_details fields,
let's introduce a flag so that it can start to encode true/false informations.
Let's start to use this flag first to clean up the only check_mapping variable.

If DCACHE_REFERENCED is set, fast_dput() will return true, and then
retain_dentry() have no chance to check DCACHE_DONTCACHE. As a result,
the dentry won't be killed and the corresponding inode can't be evicted.
In the following example, the DAX policy can't take effects unless we
do a drop_caches
If generic_drop_inode() returns true, it means iput_final() can evict
this inode regardless of whether it is dirty or not. If we check
I_DONTCACHE in generic_drop_inode(), any inode with this bit set will be
evicted unconditionally. This is not the desired behavior because
I_DONTCACHE only means

Add idle cpumask to track idle cpus in sched domain. Every time
a CPU enters idle, the CPU is set in idle cpumask to be a wakeup
target. And if the CPU is not in idle, the CPU is cleared in idle
cpumask during scheduler tick to ratelimit idle cpumask update.
When a task wakes up to select an idle

will occur.
Fix it to use devm_platform_ioremap_resource() instead of calling
platform_get_resource() and devm_ioremap().
This is detected by Coccinelle semantic patch.

This adds two atomic opcodes, both of which include the BPF_FETCH

The BPF_FETCH field can be set in bpf_insn.imm, for BPF_ATOMIC
