On architectures where flush_dcache_page is not needed, we will
end up generating all the code up to the PageSlab call. This is
because PageSlab operates on a volatile pointer and thus cannot
be optimised away.
This patch works around this by checking whether flush_dcache_page
is needed before we call PageSlab which then allows PageSlab to be
compiled awy.

Change the nx-842 common driver to wait for loading of both platform
drivers, and fail loading if the platform driver pointer is not set.
Add an independent platform driver pointer, that the platform drivers
set if they find they are able to load (i.e. if they find their platform
devicetree node(s)).
The problem is currently, the main nx-842 driver will stay loaded even
if there is no platform driver and thus no possible way it can do any
compression or decompression. This allows the crypto 842-nx driver
to load even if it won't actually work. For crypto compression users
(e.g. zswap) that expect an available crypto compression driver to
actually work, this is bad. This patch fixes that, so the 842-nx crypto
compression driver won't load if it doesn't have the driver and hardware
available to perform the compression.

This patch converts rfc4106-gcm-aesni to the new AEAD interface.
The low-level interface remains as is for now because we can't
touch it until cryptd itself is upgraded.
In the conversion I've also removed the duplicate copy of the
context in the top-level algorithm. Now all processing is carried
out in the low-level __driver-gcm-aes-aesni algorithm.

Now that type-safe init/exit functions exist, they often need
to access the underlying aead_instance. So this patch adds the

As it stands the only non-type safe functions left in the new
AEAD interface are the cra_init/cra_exit functions. It means
exposing the ugly __crypto_aead_cast to every AEAD implementor.
This patch adds type-safe init/exit functions to AEAD. Existing
algorithms are unaffected while new implementations can simply
fill in these two instead of cra_init/cra_exit.

This patch moves list.h from tools/perf/util/include/linux/list.h to
tools/include/linux/list.h to enable other libraries use macros in it,
like libbpf which will be introduced by further patches. Since list.h
depend on poison.h, poison.h is also moved.
Both file use relative path, so one '..' is removed for each header to
make them suit for new directory.
MANIFEST is also updated for 'make perf-*-src-pkg'.

We used to read file_handle twice. Once to get the amount of extra
bytes, and once to fetch the entire structure.
This may be problematic since we do size verifications only after the
first read, so if the number of extra bytes changes in userspace between
the first and second calls, we'll have an incoherent view of
file_handle.
Instead, read the constant size once, and copy that over to the final
structure without having to re-read it again.

The function ntc_adc_iio_read was assuming both a 12 bit ADC and that
pullup_uv is the same as the ADC reference voltage. If either
assumption is false, then the result is incorrect.
Attempt to use iio_convert_raw_to_processed to convert the raw value to
microvolts. It will fail for iio channels that don't support support
IIO_CHAN_INFO_SCALE; in that case fall back to the assumptions.

This adds support for the GPIO IP "UPG GIO" used on
Broadcom STB SoCs (BCM7XXX and some others). Uses
basic_mmio_gpio to instantiate a gpio_chip for each bank.
The driver assumes that it handles the base set of GPIOs
on the system and that it can start its numbering sequence
from 0, so any GPIO expanders used with it must dynamically
assign GPIO numbers after this driver has finished
registering its GPIOs.
Does not implement the interrupt-controller portion yet,
will be done in a future commit.
v2:
- change include to use <linux/gpio/driver.h> instead of
<linux/gpio.h>
- get rid of unnecessary imask member in struct bank
- rename GPIO_PER_BANK -> MAX_GPIO_PER_BANK
- always have 32 GPIOs per bank and add 'width' member in
struct bank to hold actual number of GPIOs in use
- mark of_match table as const

We did try trimming whitespace surrounding the 'model name'
field in /proc/cpuinfo since reportedly some userspace uses it
in string comparisons and there were discrepancies:
[thetango@prarit ~]# grep "^model name" /proc/cpuinfo | uniq -c | sed 's/\ /_/g'
______1_model_name :_AMD_Opteron(TM)_Processor_6272
_____63_model_name :_AMD_Opteron(TM)_Processor_6272_________________
However, there were issues with overlapping buffers, string
sizes and non-byte-sized copies in the previous proposed
solutions; see Link tags below for the whole farce.
So, instead of diddling with this more, let's simply extend what
was there originally with trimming any present trailing
whitespace. Final result is really simple and obvious.
Testing with the most insane model IDs qemu can generate, looks
good:
.model_id = " My funny model ID CPU ",
______4_model_name :_My_funny_model_ID_CPU
.model_id = "My funny model ID CPU ",
______4_model_name :_My_funny_model_ID_CPU
.model_id = " My funny model ID CPU",
______4_model_name :_My_funny_model_ID_CPU
.model_id = " ",
______4_model_name :__
.model_id = "",
______4_model_name :_15/02
