If the USB driver is enabled but the demodulator is not, we get a link error:
ERROR: "zd1301_demod_get_dvb_frontend" [drivers/media/usb/dvb-usb-v2/zd1301.ko] undefined!
ERROR: "zd1301_demod_get_i2c_adapter" [drivers/media/usb/dvb-usb-v2/zd1301.ko] undefined!
Such a configuration obviously makes no sense, but we should not fail
the build. This tries to mimic what we have for other drivers by turning
the build failure into a runtime failure.
Alternatively we could use an unconditional 'select' or 'depends on' to enforce
a sane configuration.

Back in the days when the GICv3/v4 architecture was drafted,
the command to an event to an LPI number was called MAPVI.
Later on, and to avoid confusion with the GICv4 command VMAPI,
it was renamed MAPTI. We've carried the old name for a long
time, but it gets in the way of people reading the code in
the light of the public architecture specification.
Just repaint all the references and kill the old definition.

Commit 17ce039b4e54 ("[media] cxusb: don't do DMA on stack")
added a kmalloc'ed bounce buffer for writes, but missed to do the same
for reads. As the read only happens after the write is finished, we can
reuse the same buffer.
As dvb_usb_generic_rw handles a read length of 0 by itself, avoid calling
it using the dvb_usb_generic_read wrapper function.

During the development of the GICv3/v4 architecture, it was
envisaged to have a CPU table, though the use for it was
never completely clear (the collection table serves that role
pretty well). It ended being dropped before the specification
was published, though it lived on in the driver.
In order to avoid people scratching their head too much, let's do
the same in the kernel.

The way we encode the various ITS command fields is both tedious
and error prone. Let's introduce a helper function that performs
the encoding, and convert the existing encoders to use that
helper. It also has the advantage of expressing the encoding in
a way that matches the architecture specification.

Apparently, 'count' can be negative here, which will then get turned
into a giant size argument for memcpy. Changing the sizes to 'unsigned
int' instead seems safe as we already check for maximum sizes, and it
also simplifies the code a bit.

I ran into a stack frame size warning because of the on-stack copy of
the USB device structure:
drivers/media/usb/dvb-usb-v2/dvb_usb_core.c: In function 'dvb_usbv2_disconnect':
drivers/media/usb/dvb-usb-v2/dvb_usb_core.c:1029:1: error: the frame size of 1104 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
Copying a device structure like this is wrong for a number of other reasons
too aside from the possible stack overflow. One of them is that the
dev_info() call will print the name of the device later, but AFAICT
we have only copied a pointer to the name earlier and the actual name
has been freed by the time it gets printed.
This removes the on-stack copy of the device and instead copies the
device name using kstrdup(). I'm ignoring the possible failure here
as both printk() and kfree() are able to deal with NULL pointers.

Read-allocation hints are not enabled for both the GIC-ITS and GICR
tables. This forces the hardware to always read the table contents
from an external memory (DDR) which is slow compared to cache memory.
Most of the tables are often read by hardware. So, it's better to
enable Read-allocate hints in addition to Write-allocate hints in
order to improve the GICR_PEND, GICR_PROP, Collection, Device, and
vCPU tables lookup time.

zones allow tracking multiple connections sharing identical tuples,
this is needed e.g. when tracking distinct vlans with overlapping ip
addresses (conntrack is l2 agnostic).
Thus the zone has to be set before the packet is picked up by the
connection tracker. This is done by means of 'conntrack templates' which
are conntrack structures used solely to pass this info from one netfilter
hook to the next.
The iptables CT target instantiates these connection tracking templates
once per rule, i.e. the template is fixed/tied to particular zone, can
be read-only and therefore be re-used by as many skbs simultaneously as
needed.
We can't follow this model because we want to take the zone id from
an sreg at rule eval time so we could e.g. fill in the zone id from
the packets vlan id or a e.g. nftables key : value maps.
To avoid cost of per packet alloc/free of the template, use a percpu
template 'scratch' object and use the refcount to detect the (unlikely)
case where the template is still attached to another skb (i.e., previous
skb was nfqueued ...).

This patch adds a new bitmap set type. This bitmap uses two bits to
represent one element. These two bits determine the element state in the
current and the future generation that fits into the nf_tables commit
protocol. When dumping elements back to userspace, the two bits are
expanded into a struct nft_set_ext object.
If no NFTA_SET_DESC_SIZE is specified, the existing automatic set
backend selection prefers bitmap over hash in case of keys whose size is
<= 16 bit. If the set size is know, the bitmap set type is selected if
with 16 bit kets and more than 390 elements in the set, otherwise the
hash table set implementation is used.
For 8 bit keys, the bitmap consumes 66 bytes. For 16 bit keys, the
bitmap takes 16388 bytes.

The space notation allows us to classify the set backend implementation
based on the amount of required memory. This provides an order of the
set representation scalability in terms of memory. The size field is
still left in place so use this if the userspace provides no explicit
number of elements, so we cannot calculate the real memory that this set
needs. This also helps us break ties in the set backend selection
routine, eg. two backend implementations provide the same performance.

This provides context to walk callback iterator, thus, we know if the
walk happens from the set flush path. This is required by the new bitmap

element representation.

Bit 0x100 of a page table, segment table of region table entry
can be used to disallow code execution for the virtual addresses
associated with the entry.
There is one tricky bit, the system call to return from a signal
is part of the signal frame written to the user stack. With a
non-executable stack this would stop working. To avoid breaking
things the protection fault handler checks the opcode that caused
the fault for 0x0a77 (sys_sigreturn) and 0x0aad (sys_rt_sigreturn)
and injects a system call. This is preferable to the alternative
solution with a stub function in the vdso because it works for
vdso=off and statically linked binaries as well.

The current implementation of setup_randomness uses the stack address
and therefore the pointer to the SYSIB 3.2.2 block as input data
address. Furthermore the length of the input data is the number of
virtual-machine description blocks which is typically one.
This means that typically a single zero byte is fed to
add_device_randomness.
Fix both of these and use the address of the first virtual machine
description block as input data address and also use the correct
length.

This patch
- unifies the old sclp early code and the sclp early printk code, so
they can use common functions
- makes sure all sclp early functions and variables have the same
"sclp_early" prefix
- converts the sclp early printk code into readable code by using
existing data structures instead of hard coded magic arrays
- splits the early sclp code into two files: sclp_early.c and
sclp_early_core.c. The core file contains everything that is
required by the kernel decompressor and may not call functions not
contained within the core file. Otherwise the result would be a
link error.
- changes interrupt handling to be completely synchronous. The old
early sclp code had a small window which allowed to receive several
interrupts instead of exactly the single expected interrupt. This
did hide a subtle potential bug, which is fixed with this large
rework.
- contains a couple of small cleanups.

When autonuma (Automatic NUMA balancing) marks a PTE inaccessible it
clears all the protection bits but leave the PTE valid.
With the Radix MMU, an attempt at executing from such a PTE will
take a fault with bit 35 of SRR1 set "SRR1_ISI_N_OR_G".
It is thus incorrect to treat all such faults as errors. We should
pass them to handle_mm_fault() for autonuma to deal with. The case
of pages that are really not executable is handled by the existing
test for VM_EXEC further down.
That leaves us with catching the kernel attempts at executing user
pages. We can catch that earlier, even before we do find_vma.
It is never valid on powerpc for the kernel to take an exec fault
to begin with. So fold that test with the existing test for the
kernel faulting on kernel addresses to bail out early.

The earlier comment stated that the dev_warn_once() was going to be printed
once per device. Let's fix that, as dev_warn_once() is printed only once,
no matter of the device.

After commit 5baecbcd9c9a ("perf symbols: we can now read separate
debug-info files based on a build ID") and when --symfs option is used
perf failed to pick up symbols for file with the same name between host
and sysroot specified by --symfs option. One can see message like this:
bin/bash with build id 26f0062cb6950d4d1ab0fd9c43eae8b10ca42062 not found, continuing without symbols
It happens because code added by 5baecbcd9c9a opens files directly by
dso->long_name without symbol_conf.symfs consideration, which as result
picks one from the host. It reads its build ID and later even code finds
another proper file in directory pointed by --symfs perf ignores it
because build id mismatches.
Fix is to use __symbol__join_symfs to adjust file name according to
--symfs setting. If no --symfs passed the operation would noop and picks
the same host file as before.
Also note in latter tree after 5baecbcd9c9a commit additional check for
'!dso->has_build_id' was added, so to observe error condition 'perf
record' should run with --no-buildid, so perf.data itself would not have
build id for target binary in buildid perf section and 'perf report'
will pass '!dso->has_build_id' condition. Or target binary should not
have build id, but the same binary on host has build id, again
'!dso->has_build_id' will pass in this case and incorrect build id could
be read if --symfs is used.

All events from 'perf list', except SDT events, can be directly recorded
with 'perf record'. But, the flow is little different for SDT events.
Probe points for SDT event needs to be created using 'perf probe' before
recording it using 'perf record'.
Perf shows misleading hint when a user tries to record SDT event without
first creating a probe point. Show proper hint there.
Before patch:
$ perf record -a -e sdt_glib:idle__add
event syntax error: 'sdt_glib:idle__add'
\___ unknown tracepoint
Error: File /sys/kernel/debug/tracing/events/sdt_glib/idle__add not found.
Hint: Perhaps this kernel misses some CONFIG_ setting to enable this feature?.
...
After patch:
$ perf record -a -e sdt_glib:idle__add
event syntax error: 'sdt_glib:idle__add'
\___ unknown tracepoint
Error: File /sys/kernel/debug/tracing/events/sdt_glib/idle__add not found.
Hint: SDT event cannot be directly recorded on.
Please first use 'perf probe sdt_glib:idle__add' before recording it.
...
$ perf probe sdt_glib:idle__add
Added new event:
sdt_glib:idle__add (on %idle__add in /usr/lib64/libglib-2.0.so.0.5000.2)
You can now use it in all perf tools, such as:
perf record -e sdt_glib:idle__add -aR sleep 1
$ perf record -a -e sdt_glib:idle__add
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.175 MB perf.data ]
