Pull DMA mapping updates from Christoph Hellwig:
"A huge update this time, but a lot of that is just consolidating or
removing code:
- provide a common DMA_MAPPING_ERROR definition and avoid indirect
calls for dma_map_* error checking
- use direct calls for the DMA direct mapping case, avoiding huge
retpoline overhead for high performance workloads
- merge the swiotlb dma_map_ops into dma-direct
- provide a generic remapping DMA consistent allocator for
architectures that have devices that perform DMA that is not cache
coherent. Based on the existing arm64 implementation and also used
for csky now.
- improve the dma-debug infrastructure, including dynamic allocation
of entries (Robin Murphy)
- default to providing chaining scatterlist everywhere, with opt-outs
for the few architectures (alpha, parisc, most arm32 variants) that
can't cope with it
- misc sparc32 dma-related cleanups
- remove the dma_mark_clean arch hook used by swiotlb on ia64 and
replace it with the generic noncoherent infrastructure
- fix the return type of dma_set_max_seg_size (Niklas Söderlund)
- move the dummy dma ops for not DMA capable devices from arm64 to
common code (Robin Murphy)
- ensure dma_alloc_coherent returns zeroed memory to avoid kernel
data leaks through userspace. We already did this for most common
architectures, but this ensures we do it everywhere.
dma_zalloc_coherent has been deprecated and can hopefully be
removed after -rc1 with a coccinelle script"

Avoid expensive indirect calls in the fast path DMA mapping
operations by directly calling the dma_direct_* ops if we are using
the directly mapped DMA operations.

While the dma-direct code is (relatively) clean and simple we actually
have to use the swiotlb ops for the mapping on many architectures due
to devices with addressing limits. Instead of keeping two
implementations around this commit allows the dma-direct
implementation to call the swiotlb bounce buffering functions and
thus share the guts of the mapping implementation. This also
simplified the dma-mapping setup on a few architectures where we
don't have to differenciate which implementation to use.

dma-debug is now capable of adding new entries to its pool on-demand if
the initial preallocation was insufficient, so the IOMMU_LEAK logic no
longer needs to explicitly change the pool size. This does lose it the
ability to save a couple of megabytes of RAM by reducing the pool size
below its default, but it seems unlikely that that is a realistic
concern these days (or indeed that anyone is actively debugging AGP
drivers' DMA usage any more). Getting rid of dma_debug_resize_entries()
will make room for further streamlining in the dma-debug code itself.
Removing the call reveals quite a lot of cruft which has been useless
for nearly a decade since commit 19c1a6f5764d ("x86 gart: reimplement
IOMMU_LEAK feature by using DMA_API_DEBUG"), including the entire
'iommu=leak' parameter, which controlled nothing except whether
dma_debug_resize_entries() was called or not.

show_regs() shows the CS in the CPU register instead of the value in
regs. This means that we'll probably print "CS: 0010" almost all
the time regardless of what was actually in CS when the kernel
malfunctioned. This gives a particularly confusing result if we
OOPSed due to an implicit supervisor access from user mode.

There is one user of __kernel_fpu_begin() and before invoking it,
it invokes preempt_disable(). So it could invoke kernel_fpu_begin()
right away. The 32bit version of arch_efi_call_virt_setup() and
arch_efi_call_virt_teardown() does this already.
The comment above *kernel_fpu*() claims that before invoking
__kernel_fpu_begin() preemption should be disabled and that KVM is a
good example of doing it. Well, KVM doesn't do that since commit
f775b13eedee2 ("x86,kvm: move qemu/guest FPU switching out to vcpu_run")
so it is not an example anymore.
With EFI gone as the last user of __kernel_fpu_{begin|end}(), both can
be made static and not exported anymore.

The comment above __raw_xsave_addr() claims that the function does not
work for compacted buffers and was introduced in:
b8b9b6ba9dec3 ("x86/fpu: Allow setting of XSAVE state")
In this commit, the function was factored out of get_xsave_addr() and
this function claims that it works with "standard format or compacted
format of xsave area". It accesses the "xstate_comp_offsets" variable
for the actual offset and it was introduced in commit
7496d6458fe32 ("Define kernel API to get address of each state in xsave area")
Based on the code (back then and now):
- xstate_offsets holds the standard offset.
- if compacted mode is not supported then xstate_comp_offsets gets the
xstate_offsets copied.
- if compacted mode is supported then xstate_comp_offsets will hold the
offset for the compacted buffer.
Based on that the function works for compacted buffers as long as the
CPU supports it and this what we care about.
Remove the "Note:" which is not accurate.

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.

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.'

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.
[ bp: Adjust to new changes. ]

Convert the CPU equivalence table into a proper struct in preparation
for tracking also the size of this table.

Now that they have the required functionality, use them to verify the
equivalence table and each patch, thus making parse_container() more
readable.

Have it return 0 on success, positive value when the current patch
should be skipped and negative on error.

Instead of traversing the equivalence table, compute the family a patch
is for, from the processor revision ID in the microcode header.
