We zero out the entire trace buffer used for ETR before it is enabled,
for helping with debugging. With the addition of scatter-gather mode,
the buffer could be bigger and non-contiguous.

as and when needed.

After 43838a23a05f ("random: fix crng_ready() test") early boot calls
to get_random_bytes() will warn on each cpu on x86 because the crng
is not initialized. For example,
random: get_random_bytes called from start_kernel+0x8e/0x587 with crng_init=0
x86 only uses get_random_bytes() for better ran

If the device has not been registered, or there is work pending,
we should reschedule a sch_event call again.

There is at least one relevant guest OS that doesn't set the IDA flags in
the ORB as we would like them, but never uses any IDA. So instead of
saying -EOPNOTSUPP when observing an ORB, such that a channel program
specified by it could be a not supported one, let us say -EOPNOTSU

Let's avoid free on ccw->cda that points to a guest address
or an already freed memory area by setting it to NULL if memory
allocation didn't happen or failed.

The kernel doc description for usage of the struct pfn_array in
pfn_array_pin() is unnecessary long. Let's shorten it by describing
the contents of the struct pfn_array fields at the struct's definition
instead.

This refactors pfn_array_alloc_pin() and also improves it by adding
defensive code in error handling so that calling pfn_array_unpin_free()
after error return won't lead to problem. This mainly does:
1. Merge pfn_array_pin() into pfn_array_alloc_pin(), since there is no

Add some tracepoints so we can inspect what is not working as is should.

If phys_addr is not page aligned, ioremap_page_range() will align down it
when get pfn by phys_addr >> PAGE_SHIFT. An example in arm64 system with
64KB page size:
phys_addr: 0xefff8000
res->start: 0x0
res->end: 0x0
PCI_IOBASE: 0x7fdffee0
This will remap virtual address 0x7f
