Merge tag 'libnvdimm-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm and DAX updates from Dan Williams:
"New support for clearing memory errors when a file is in DAX mode,
alongside with some other fixes and cleanups.
Previously it was only possible to clear these errors using a truncate
or hole-punch operation to trigger the filesystem to reallocate the
block, now, any page aligned write can opportunistically clear errors
as well.
This change spans x86/mm, nvdimm, and fs/dax, and has received the
appropriate sign-offs. Thanks to Jane for her work on this.
Summary:
- Add support for clearing memory error via pwrite(2) on DAX
- Fix 'security overwrite' support in the presence of media errors
- Miscellaneous cleanups and fixes for nfit_test (nvdimm unit tests)"
* tag 'libnvdimm-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm:
pmem: implement pmem_recovery_write()
pmem: refactor pmem_clear_poison()
dax: add .recovery_write dax_operation
dax: introduce DAX_RECOVERY_WRITE dax access mode
mce: fix set_mce_nospec to always unmap the whole page
x86/mce: relocate set{clear}_mce_nospec() functions
acpi/nfit: rely on mce->misc to determine poison granularity
testing: nvdimm: asm/mce.h is not needed in nfit.c
testing: nvdimm: iomap: make __nfit_test_ioremap a macro
nvdimm: Allow overwrite in the presence of disabled dimms
tools/testing/nvdimm: remove unneeded flush_workqueue
