Hi,
This patchset makes the cpufreq_cooling driver reuse the CPU utilization
metric provided by the scheduler instead of depending on idle and busy
times of a CPU, which aren't that accurate to measure the busyness of a

patch 2/
Several parts of the kernel are already using the effective CPU
utilization (as seen by the scheduler) to get the current load on the
CPU, do the same here instead of depending on the idle time of the CPU,
which isn't that accurate comparatively.
This is also the right thing to do as it makes the
There is nothing schedutil specific in schedutil_cpu_util(), rename it

__irq_domain_alloc_irqs() can already handle virq==-1 and free
descriptors if it failed allocating hardware interrupts so let's skip
this extra step.

This moves hierarchical domain's irqs cleanup into the kobject release
hook to make irq_domain_free_irqs() as simple as kobject_put.

This is another attempt to add reference counting to IRQ
descriptors; or - more to the point - reuse already existing
kobj from irq_desc. This allows the same IRQ to be used several
times (such as legacy PCI INTx) and when disposing those, only
the last reference drop clears the hardware mappings.
There are 10 users of __irq_domain_alloc_irqs() and only one - IOAPIC -
passes realloc==true. There is no obvious reason for handling this
specific case in the generic code.
This splits out __irq_domain_alloc_irqs_data() to make it clear what
IOAPIC does and makes __irq_domain_alloc_irqs() cleaner
The two previous patches made @realloc obsolete. This finishes removing it.

Permit the user to specify the erase page size as a parameter.
This solves two problems:
- phram can access images made by mkfs.jffs2. mkfs.jffs2 won't
create images with erase sizes less than 8KiB; many architectures
define PAGE_SIZE as 4KiB.
- Allows more effective use of small capacity device

Currently struct irqentry_state_t only contains a single bool value
which makes passing it by value is reasonable. However, future patches
add information to this struct. This includes the PKRS thread state,
included in this series, as well as information to store kmap reference
