v2:
- drop completion variables and flush workqueue [pmladek]
- comment typo/pr_info cleanup [kbabulal/mbenes]
- cleanup goto ret assignations [pmladek]
- allocate pndup[]'s, leave some svar allocations to
shadow_get_or_alloc() [pmladek]
- change allocation order for cleaner test dmesg output [pmladek]
The test-klp-callbacks change implements a synchronization replacement of
initial code which relied on solely on sleep delays. Remove the sleeps
and pass a block_transition flag from test script to module. Use
flush_workqueue() to serialize module output for test result
consideration.
The test-klp-shadow-vars changes first refactors the code to be more of
a readable example as well as continuing to verify the component code.
The patch is broken in two to display the renaming and restructuring in
part 1 and the addition and change of logic in part 2. The last change
frees memory before bailing in case of errors.

2.25.4
This patch series adds partial read support in request_firmware_into_buf.
In order to accept the enhanced API it has been requested that kernel
selftests and upstreamed driver utilize the API enhancement and so
are included in this patch series.
Also in this patch series is the addition of a new Broadcom VK driver
utilizing the new request_firmware_into_buf enhanced API.
Further comment followed to add IMA support of the partial reads
originating from request_firmware_into_buf calls.
Changes from v5:
- add IMA FIRMWARE_PARTIAL_READ support
- change kernel pread flags to enum
- removed legacy support from driver
- driver fixes
Changes from v4:
- handle reset issues if card crashes
- allow driver to have min required msix
- add card utilization information
Changes from v3:
- fix sparse warnings
- fix printf format specifiers for size_t
- fix 32-bit cross-compiling reports 32-bit shifts
- use readl/writel,_relaxed to access pci ioremap memory,
removed memory barriers and volatile keyword with such change
- driver optimizations for interrupt/poll functionalities
Changes from v2:
- remove unnecessary code and mutex locks in lib/test_firmware.c
- remove VK_IOCTL_ACCESS_BAR support from driver and use pci sysfs instead
- remove bitfields
- remove Kconfig default m
- adjust formatting and some naming based on feedback
- fix error handling conditions
- use appropriate return codes
- use memcpy_toio instead of direct access to PCIE bar
