On my machine, a kexec with this driver loaded in the old kernel
causes a very long delay on boot in the kexec'ed kernel,
most likely due to unclean shutdown prior to that.
Unloading thunderbolt driver prior to kexec allows kexec to work as fast
as regular kernel boot, as well as adding this

While trying to use kexec on my desktop,
which has Titan Ridge Thunderbolt add-on card,
I noticed that after a kexec, system hangs
for about a minute in the 'wating for udev devices
to settle' phase of the boot.
I found out that if I unload the thunderbolt driver
prior to the kexec, then it works

Deferred struct page init is a bottleneck in kernel boot--the biggest
for us and probably others. Optimizing it maximizes availability for
large-memory systems and allows spinning up short-lived VMs as needed
without having to leave them running. It also benefits bare metal
machines hosting VMs
padata_driver_exit() is unnecessary because padata isn't built as a
module and doesn't exit.
padata's init routine will soon allocate memory, so getting rid of the
exit function now avoids pointless code to free it.

padata will soon initialize the system's struct pages in parallel, so it
needs to be ready by page_alloc_init_late().
The error return from padata_driver_init() triggers an initcall warning,
so add a warning to padata_init() to avoid silent failure.

Sometimes the kernel doesn't take full advantage of system memory
bandwidth, leading to a single CPU spending excessive time in
initialization paths where the data scales with memory size.
Multithreading naturally addresses this problem.
Extend padata, a framework that handles many parallel yet
padata allocates per-CPU, per-instance work structs for parallel jobs.
A do_parallel call assigns a job to a sequence number and hashes the
number to a CPU, where the job will eventually run using the
corresponding work.
This approach fit with how padata used to bind a job to each CPU

If a metric contains the duration_time event then the event is placed
outside of the metric's group of events. Rather than split the group,
make it so the duration_time is immediately after the group.

A metric group contains multiple metrics. These metrics may use the same

On MMP3, the camera block lives on na separate power island. We want to
turn it off if the CCIC is not in use to conserve power.

Serious,
HPB is a completely fucked up concept and we shoud not merge it at all.
Especially not with a crazy bullshit vendor extension layer that makes

Qualcomm controller needs to be in hibern8 before scaling clocks.
This change puts the controller in hibern8 state before scaling
and brings it out after scaling of clocks.

Qualcomm controllers need to be in hibern8 before scaling up
or down the clocks. Hence, export the hibern8 entry function.

The commit 8c47b6ff29e3 ("KVM: PPC: Book3S HV: Check caller of H_SVM_*
Hcalls") added checks of secure bit of SRR1 to filter out the Hcall
reserved to the Ultravisor.
However, the Hcall H_SVM_INIT_ABORT is made by the Ultravisor passing the
context of the VM calling UV_ESM. This allows the
