The xfeature mask is 64-bit so a shift from a number to its mask should
have ULL suffix or else bits above position 31 will be lost. This is not
a problem now but should XFEATURE_MASK_SUPERVISOR gain a bit >31 then
this check won't catch it.
Use BIT_ULL() to compute a mask from a number.

nr_cpu_ids can be limited on the command line via nr_cpus=. This can break the
logical package management because it results in a smaller number of packages
while in kdump kernel.
Check below case:
There is a two sockets system, each socket has 8 cores, which has 16 logical
cpus while HT was turn on.
0 1 2 3 4 5 6 7 | 16 17 18 19 20 21 22 23
cores on socket 0 threads on socket 0
8 9 10 11 12 13 14 15 | 24 25 26 27 28 29 30 31
cores on socket 1 threads on socket 1
While starting the kdump kernel with command line option nr_cpus=16 panic
was triggered on one of the cpus 24-31 eg. 26, then online cpu will be
1-15, 26(cpu 0 was disabled in kdump), ncpus will be 16 and
__max_logical_packages will be 1, but actually two packages were booted on.
This issue can reproduced by set kdump option nr_cpus=<real physical core
numbers>, and then trigger panic on last socket's thread, for example:
taskset -c 26 echo c > /proc/sysrq-trigger
Use total_cpus which will not be limited by nr_cpus command line to calculate
the value of __max_logical_packages.

get_scattered_cpuid_leaf() was added[1] to help KVM rebuild hardware-
defined leafs that are rearranged by Linux to avoid bloating the
x86_capability array. Eventually, the last consumer of the function was
removed[2], but the function itself was kept, perhaps even intentionally
as a form of documentation.
Remove get_scattered_cpuid_leaf() as it is currently not used by KVM.
Furthermore, simply rebuilding the "real" leaf does not resolve all of
KVM's woes when it comes to exposing a scattered CPUID feature, i.e.
keeping the function as documentation may be counter-productive in some
scenarios, e.g. when KVM needs to do more than simply expose the leaf.

It was marked __visible so that it is visible outside of the current

When building the kernel with W=1 we get a lot of -Wmissing-prototypes
warnings, which are trivial in nature and easy to fix - and which may
mask some real future bugs if the prototypes get out of sync with
the function definition.
This patch fixes most of -Wmissing-prototypes warnings which
are in the root directory of arch/x86/kernel, not including
the subdirectories.
These are the warnings fixed in this patch:

Pull x86 AMD northbridge updates from Ingo Molnar:
"Update DF/SMN access and k10temp for AMD F17h M30h, by Brian Woods:
'Updates the data fabric/system management network code needed to get
k10temp working for M30h. Since there are now processors which have
multiple roots per DF/SMN interface, there needs to some logic which
skips N-1 root complexes per DF/SMN interface. This is because the
root complexes per interface are redundant (as far as DF/SMN goes).
These changes shouldn't effect past processors and, for F17h M0Xh,
the mappings stay the same.'
The hwmon changes were seen and acked by hwmon maintainer Guenter Roeck"

Add support for new processors which have multiple PCI root complexes
per data fabric/system management network interface. If there are (N)
multiple PCI roots per DF/SMN interface, then the PCI roots are
redundant (as far as SMN/DF access goes). For each DF/SMN interface:
map to the first available PCI root and skip the next N-1 PCI roots so
the following DF/SMN interface get mapped to a correct PCI root.
Ex:
DF/SMN 0 -> 60
40
20
00
DF/SMN 1 -> e0
c0
a0
80

Pull x86 microcode loading updates from Borislav Petkov:
"This update contains work started by Maciej to make the microcode
container verification more robust against all kinds of corruption and
also unify verification paths between early and late loading.
The result is a set of verification routines which validate the
microcode blobs before loading it on the CPU. In addition, the code is
a lot more streamlined and unified.
In the process, some of the aspects of patch handling and loading were
simplified.

Currently, the code scanning the CPU equivalence table read from a
microcode container file assumes that it actually contains a terminating
zero entry.
Check also the size of this table to make sure that no reads past its
end happen, in case there's no terminating zero entry at the end of the
table.

Add container and patch verification functions to the AMD microcode
update driver.
These functions check whether a passed buffer contains the relevant
structure, whether it isn't truncated and (for actual microcode patches)
whether the size of a patch is not too large for a particular CPU family.
By adding these checks as separate functions the actual microcode loading
code won't get interspersed with a lot of checks and so will be more
readable.

verify_patch_size() verifies whether the remaining size of the microcode
container file is large enough to contain a patch of the indicated size.
However, the section header length is not included in this indicated
size but it is present in the leftover file length so it should be
subtracted from the leftover file length before passing this value to
verify_patch_size().

Pull x86 cache control updates from Borislav Petkov:
- The generalization of the RDT code to accommodate the addition of
AMD's very similar implementation of the cache monitoring feature.
This entails a subsystem move into a separate and generic
arch/x86/kernel/cpu/resctrl/ directory along with adding
vendor-specific initialization and feature detection helpers.
Ontop of that is the unification of user-visible strings, both in the
resctrl filesystem error handling and Kconfig.
Provided by Babu Moger and Sherry Hurwitz.

Chatre.

rdt_find_domain() returns an ERR_PTR() that is generated from a provided
domain id when the value is negative.
Care needs to be taken when creating an ERR_PTR() from this value
because a subsequent check using IS_ERR() expects the error to
be within the MAX_ERRNO range. Using an invalid domain id as an
ERR_PTR() does work at this time since this is currently always -1.
Using this undocumented assumption is fragile since future users of
rdt_find_domain() may not be aware of thus assumption.
Two related issues are addressed:
- Ensure that rdt_find_domain() always returns a valid error value by
forcing the error to be -ENODEV when a negative domain id is provided.
- In a few instances the return value of rdt_find_domain() is just
checked for NULL - fix these to include a check of ERR_PTR.

The Smatch static checker reports the following error after commit:
a36c5ff560fb ("x86/resctrl: Bring cbm_validate() into the resource structure"):
arch/x86/kernel/cpu/resctrl/ctrlmondata.c:227 parse_cbm()
error: uninitialized symbol 'cbm_val'.
arch/x86/kernel/cpu/resctrl/ctrlmondata.c:236 parse_cbm()
error: uninitialized symbol 'cbm_val'.
This could happen if ->cbm_validate() is NULL which could leave cbm_val
uninitialized.
However, there is no case where ->cbm_validate() can be NULL as it is
initialized based on a vendor check. So it is either an Intel or an AMD
version it points to. And in both the cases it is initialized properly.
Thus, remove the first check.
Verified the fix running Smatch.

The last_cmd_status sequence buffer contains user-visible messages
(accessed via /sys/fs/resctrl/info/last_cmd_status) that detail any
errors encountered while interacting with the resctrl filesystem.
rdt_last_cmd_printf() and rdt_last_cmd_puts() are the two calls
available to respectively print a string with format specifiers or a
simple one (which contains no format specifiers) to the last_cmd_status
buffer.
A few occurrences exist where rdt_last_cmd_printf() is used to print
a simple string. Doing so does not result in incorrect result or
incorrect behavior, but rdt_last_cmd_puts() is the function intended to
be used in these cases, as it is faster and it doesn't need to do the
vsnprintf() formatting.
Fix these occurrences to use rdt_last_cmd_puts() instead. While doing
so, fix two typos that were recently introduced into two of these simple
strings.

Enable QOS feature on AMD.
Following QoS sub-features are supported on AMD if the underlying
hardware supports it:
- L3 Cache allocation enforcement
- L3 Cache occupancy monitoring
- L3 Code-Data Prioritization support
- Memory Bandwidth Enforcement (Allocation)
The specification is available at:
https://developer.amd.com/wp-content/resources/56375.pdf
There are differences in the way some of the features are implemented.
Separate those functions and add those as vendor specific functions.
The major difference is in MBA feature:
- AMD uses CPUID leaf 0x80000020 to initialize the MBA features.
- AMD uses direct bandwidth value instead of delay based on bandwidth values.
- MSR register base addresses are different for MBA.
- AMD allows non-contiguous L3 cache bit masks.
