dt-bindings: virtio: Convert virtio,pci-iommu to DT schema

Convert the binding that describes the virtio-pci based IOMMU to DT
schema. Change the compatible string to "pci<vendor>,<device>", which is
defined by the PCI Bus Binding, but keep "virtio,pci-iommu" as an option
for backward compatibility.

dt-bindings: timer: arm,arch_timer: Allow dual compatible string

Since the Armv7 and Armv8 architected timers are compatible, it is valid
to expose a devicetree node with compatible string "arm,armv8-timer"
followed by "arm,armv7-timer". For example a 32-bit guest running on a
64-bit machine may look for the v7 string even though the hardware is v8.
VMMs such as QEMU and kvmtool have been using this compatible string for
some time. Clean up the compatible list a little and add the dual
option.

of/fdt: Don't calculate initrd size from DT if start > end

If the properties 'linux,initrd-start' and 'linux,initrd-end' of
the chosen node populated from the bootloader, eg. U-Boot, are so that
start > end, then the phys_initrd_size calculated from end - start is
negative that subsequently gets converted to a high positive value for
being unsigned long long. Then, the memory region with the (invalid)
size is added to the bootmem and attempted being paged in paging_init()
that results in the kernel fault.

For example, on the FVP ARM64 system I'm running, the U-Boot populates
the 'linux,initrd-start' with 8800_0000 and 'linux,initrd-end' with 0.
The phys_initrd_size calculated is then ffff_ffff_7800_0000
(= 0 - 8800_0000 = -8800_0000 + ULLONG_MAX + 1). paging_init() then
attempts to map the address 8800_0000 + ffff_ffff_7800_0000 and oops'es
as below.

It should be stressed, it is generally a fault of the bootloader's with
the kernel relying on it, however we should not allow the bootloader's
misconfiguration to lead to the kernel oops. Not only the kernel should be
bullet proof against it but also finding the root cause of the paging
fault spanning over the bootloader, DT, and kernel may happen is not so
easy.

In commit 853a78a7d6c7 (dt-bindings: leds: Add LED_COLOR_ID definitions,
Sun Jun 9 20:19:04 2019 +0200) the most basic color definitions where
added. However, there's a little more very common LED colors.

While the documentation states 'add what is missing', engineers tend to
be lazy and will just use what currently exists. So this patch will take
(a) list from online retailers [0], [1], [2] and use the common LED colors from
there, this being reasonable as this is what is currently available to purchase.

Note, that LIME seems to be the modern take to 'Yellow-green' or
'Yellowish-green' from some older datasheets.

perf test: Refactor shell tests allowing subdirs

This is a prelude to adding more tests to shell tests and in order to
support putting those tests into subdirectories, I need to change the
test code that scans/finds and runs them.

To support subdirs I have to recurse so it's time to refactor the code
to allow this and centralize the shell script finding into one location
and only one single scan that builds a list of all the found tests in
memory instead of it being duplicated in 3 places.

This code also optimizes things like knowing the max width of desciption
strings (as we can do that while we scan instead of a whole new pass of
opening files).

It also more cleanly filters scripts to see only *.sh files thus
skipping random other files in directories like *~ backup files, other
random junk/data files that may appear and the scripts must be
executable to make the cut (this ensures the script lib dir is not seen
as scripts to run).

This avoids perf test running previous older versions of test scripts
that are editor backup files as well as skipping perf.data files that
may appear and so on.

The metrics are based on TMA 4.4 full, add new metrics “UNCORE_FREQ” for
broadwellde.

Use script at:

  https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py

to download and generate the latest events and metrics. Manually copy
the broadwellde files into perf.

perf jevents: Fold strings optimization

If a shorter string ends a longer string then the shorter string may
reuse the longer string at an offset. For example, on x86 the event
arith.cycles_div_busy and cycles_div_busy can be folded, even though
they have difference names the strings are identical after 6
characters. cycles_div_busy can reuse the arith.cycles_div_busy string
at an offset of 6.

In pmu-events.c this looks like the following where the 'also:' lists
folded strings:

/* offset=177541 */ "arith.cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000" /* also: cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000 */

As jevents.py combines multiple strings for an event into a larger
string, the amount of folding is minimal as all parts of the event must
align. Other organizations can benefit more from folding, but lose space
by say recording more offsets.

perf jevents: Compress the pmu_events_table

The pmu_events array requires 15 pointers per entry which in position
independent code need relocating. Change the array to be an array of
offsets within a big C string. Only the offset of the first variable is
required, subsequent variables are stored in order after the \0
terminator (requiring a byte per variable rather than 4 bytes per
offset).

The file size savings are:

no jevents - the same 19,788,464bytes
x86 jevents - ~16.7% file size saving 23,744,288bytes vs 28,502,632bytes
all jevents - ~19.5% file size saving 24,469,056bytes vs 30,379,920bytes
default build options plus NO_LIBBFD=1.

For example, the x86 build savings come from .rela.dyn and
.data.rel.ro becoming smaller by 3,157,032bytes and 3,042,016bytes
respectively. .rodata increases by 1,432,448bytes, giving an overall
4,766,600bytes saving.

To make metric strings more shareable, the topic is changed from say
'skx metrics' to just 'metrics'.

To try to help with the memory layout the pmu_events are ordered as used
by perf qsort comparator functions.

perf pmu-events: Don't assume pmu_event is an array

The current code assumes that a struct pmu_event can be iterated over
forward until a NULL pmu_event is encountered.

This makes it difficult to refactor pmu_event.

Add a loop function taking a callback function that's passed the struct
pmu_event.

This way the pmu_event is only needed for one element and not an entire
array.

Switch existing code iterating over the pmu_event arrays to use the new
loop function pmu_events_table_for_each_event.

io_uring: make io_kiocb_to_cmd() typesafe

We need to make sure (at build time) that struct io_cmd_data is not
casted to a structure that's larger.

fs: don't randomize struct kiocb fields

This is a size sensitive structure and randomizing can introduce extra
padding that breaks io_uring's fixed size expectations. There are few
fields here as it is, half of which need a fixed order to optimally
pack, so the randomization isn't providing much.
