+Subject: dm zoned: assign max_io_len correctly
+
+From: Hou Tao <houtao1@huawei.com>
+
+commit 7b2377486767503d47265e4d487a63c651f6b55d upstream.
+
+The unit of max_io_len is sector instead of byte (spotted through
+code review), so fix it.
+
+Fixes: 3b1a94c88b79 ("dm zoned: drive-managed zoned block device target")

+Subject: efi: Make it possible to disable efivar_ssdt entirely
+
+From: Peter Jones <pjones@redhat.com>
+
+commit 435d1a471598752446a72ad1201b3c980526d869 upstream.
+
+In most cases, such as CONFIG_ACPI_CUSTOM_DSDT and
+CONFIG_ACPI_TABLE_UPGRADE, boot-time modifications to firmware tables
+are tied to specific Kconfig options.  Currently this is not the case
+for modifying the ACPI SSDT via the efivar_ssdt kernel command line
+option and associated EFI variable.
+
+This patch adds CONFIG_EFI_CUSTOM_SSDT_OVERLAYS, which defaults
+disabled, in order to allow enabling or disabling that feature during
+the build.
