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.

git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity into next-integrity
From Mimi:
In Linux 4.19, a new LSM hook named security_kernel_load_data was
upstreamed, allowing LSMs and IMA to prevent the kexec_load
syscall. Different signature verification methods exist for verifying
the kexec'ed kernel image. This pull request adds additional support
in IMA to prevent loading unsigned kernel images via the kexec_load
syscall, independently of the IMA policy rules, based on the runtime
"secure boot" flag. An initial IMA kselftest is included.
In addition, this pull request defines a new, separate keyring named
".platform" for storing the preboot/firmware keys needed for verifying
the kexec'ed kernel image's signature and includes the associated IMA
kexec usage of the ".platform" keyring.
(David Howell's and Josh Boyer's patches for reading the
preboot/firmware keys, which were previously posted for a different
use case scenario, are included here.)

cpa_flush() function
Note that the cache flush loop in cpa_flush_*() is identical when we
use __cpa_addr(); further observe that flush_tlb_kernel_range() is a
special case of to the cpa_flush_array() TLB invalidation code.
This then means the two functions are virtually identical. Fold these
two functions into a single cpa_flush() call.

Currently __change_page_attr_set_clr() will modify cpa->vaddr when
!(CPA_ARRAY | CPA_PAGES_ARRAY), whereas in the array cases it will
increment cpa->curpage.
Change __cpa_addr() such that its @idx argument also works in the
!array case and use cpa->curpage increments for all cases.
NOTE: since cpa_data::numpages is 'unsigned long' so should cpa_data::curpage be.
NOTE: after this only cpa->numpages is still modified.

Since commit 0e00a8c9fd92 ("powerpc: Allow CPU selection

After converting the PXA driver to use GPIO descriptors for
card detect and write protect it is relatively simple to
convert it to also use a descriptor for getting the optional
power control GPIO.
The polarity inversion flag can also go away from the platform
data since this is indicated in the GPIO machine descriptor
table.

This deletes the platform data passed for card detect and
write protect from various PXA machines.
Make sure to keep .gpio_card_ro_invert as this is still in
use by some machines and needed to set the right flag to
the MMC core (will be cleaned up later).

The Palm27x devices set up the MMC card detect and
write protect lines with a special helper function.
Augment this helper function to also accept an optional
GPIO descriptor table and pass and register this for
all the Palm27x devices in that family.

This adds GPIO descriptor look-up tables for a whole bunch
of PXA boards with MMC card detect (CD) and write protect (WP)
GPIO lines, so we can move away from the hard-coded GPIO
numberspace.
In some cases the platforms were compulsively including the
<linux/gpio.h> header even if they weren't actually using
it, and in these cases I simply replaced that inclusion with
the more appropriate <linux/gpio/machine.h> which is what
board files should be including most of the time.
