These are all calling x86 entry code functions, so move them close
to other entry code.
Change lib-y to obj-y: there's no real difference between the two
as we don't really drop any of them during the linking stage, and
obj-y is the more common approach for core kernel object code.

Currently, openvswitch tries to disable LRO from the user space. This does
not work correctly when the device added is a vlan interface, though.
Instead of dealing with possibly complex stacked cross name space relations
in the user space, do the same as bridging does and call dev_disable_lro in
the kernel.

Currently the bpf frame pointer is set to the old r15. This is
wrong because of packed stack. Fix this and adjust the frame pointer
to respect packed stack. This now generates a prolog like the following:

On s390x we have to provide 160 bytes stack space before we can call
the next function. From the 160 bytes that we got from the previous
function we only use 11 * 8 bytes and have 160 - 11 * 8 bytes left.
Currently for BPF we allocate additional 160 - 11 * 8 bytes for the
next function. This is wrong because then the next function only gets:
(160 - 11 * 8) + (160 - 11 * 8) = 2 * 72 = 144 bytes
Fix this and allocate enough memory for the next function.

The function get_ohm_of_thermistor has both the measured voltage and the
pullup voltage available in microvolts. But it was promptly converting
both to millivolts before using them to calculate the thermistor
resistance. That conversion unnecessarily hurt the precision of the
calculation.
For example, take the ncpXXwb473 connected to 5000 mV and pulled down
through a 47000 ohm resistor. At 25 C, the resistance of the thermistor
is 47000 ohms. The measured voltage will be 2500 mV. If we measure
instead 2501 mV, then the calculated resistance will be 46962 ohms --
a difference of 38 ohms. So the precision of the resistance estimate
could be increased by 38X by doing the calculations in microvolts.

Before patch ba92732e9808 ('perf kmaps: Check kmaps to make code more

This is because __kmod_path__parse treats '[' leading names as kernel
name instead of names of kernel module.
If perf.data contains build information and the buildid of such modules
can be found, the dso->kernel of it will be set to DSO_TYPE_KERNEL by
__event_process_build_id(), not kernel module.
It will then be passed to dso__load() -> dso__load_kernel_sym() ->
dso__load_kcore() if --kallsyms is provided.
The refered patch adds NULL pointer checker to avoid segfault. However,
such kernel modules are still processed incorrectly.
This patch fixes __kmod_path__parse, makes it treat names like
'[test_module]' as kernel modules.
kmod-path.c is also update to reflect the above changes.

Nothing in <asm/io.h> uses anything from <linux/vmalloc.h>, so
remove it from there and fix up the resulting build problems
triggered on x86 {64|32}-bit {def|allmod|allno}configs.
The breakages were triggering in places where x86 builds relied
on vmalloc() facilities but did not include <linux/vmalloc.h>
explicitly and relied on the implicit inclusion via <asm/io.h>.
Also add:
- <linux/init.h> to <linux/io.h>
- <asm/pgtable_types> to <asm/io.h>
... which were two other implicit header file dependencies.

The driver worked around an error in the MAYA44 USB(+)'s mixer unit
descriptor by aborting before parsing the missing field. However,
aborting parsing too early prevented parsing of the other units
connected to this unit, so the capture mixer controls would be missing.
Fix this by moving the check for this descriptor error after the parsing
of the unit's input pins.

Peter Zijstra noticed that in arch/x86/Kconfig there are a lot
of X86_{32,64} clauses in the X86 symbol, plus there are a number
of similar selects in the X86_32 and X86_64 config definitions
as well - which all overlap in an inconsistent mess.
So:
- move all select's from X86_32 and X86_64 to the X64 config
option
- sort their names, so that duplications are easier to spot
- align their if clauses, so that they are easier to identify
at a glance - and so that weirdnesses stand out more

Scatter gather lists can be created with more available entries than are
actually used (e.g. using sg_init_table() to reserve a specific number
of sg entries, but in actuality using something less than that based on
the data length). The caller sometimes fails to mark the last entry
with sg_mark_end(). In these cases, sg_nents() will return the original
size of the sg list as opposed to the actual number of sg entries that
contain valid data.
On arm64, if the sg_nents() value is used in a call to dma_map_sg() in
this situation, then it causes a BUG_ON in lib/swiotlb.c because an
"empty" sg list entry results in dma_capable() returning false and
swiotlb trying to create a bounce buffer of size 0. This occurred in
the userspace crypto interface before being fixed by
0f477b655a52 ("crypto: algif - Mark sgl end at the end of data")
Protect against this by using the new sg_nents_for_len() function which
returns only the number of sg entries required to meet the desired
length and supplying that value to dma_map_sg().

When performing a dma_map_sg() call, the number of sg entries to map is
required. Using sg_nents to retrieve the number of sg entries will
return the total number of entries in the sg list up to the entry marked
as the end. If there happen to be unused entries in the list, these will
still be counted. Some dma_map_sg() implementations will not handle the
unused entries correctly (lib/swiotlb.c) and execute a BUG_ON.
The sg_nents_for_len() function will traverse the sg list and return the
number of entries required to satisfy the supplied length argument. This
can then be supplied to the dma_map_sg() call to successfully map the
sg.

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

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 moves kernel.h from tools/perf/util/include/linux/kernel.h
to tools/include/linux/kernel.h to enable other libraries use macros in
it, like libbpf which will be introduced by further patches.
MANIFEST is also updated for 'make perf-*-src-pkg'.

Make the check to skip the rate check more lax, so that it applies
to all hw_version 4 models.
This fixes the touchpad not being detected properly on Asus PU551LA

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.
