[PATCH] efi: make the min and max mmap slack slots configurable

by Hamza Mahfooz

Recent platforms require more slack slots than the current value of EFI_MMAP_NR_SLACK_SLOTS, otherwise they fail to boot. So, introduce EFI_MIN_NR_MMAP_SLACK_SLOTS and EFI_MAX_NR_MMAP_SLACK_SLOTS and use them to determine a number of slots that the platform is willing to accept.

[PATCH AUTOSEL 5.4 1/7] scsi: qla1280: Fix hw revision numbering for ISP1020/1040

by Sasha Levin

From: Magnus Lindholm <linmag7(a)gmail.com> [ Upstream commit c064de86d2a3909222d5996c5047f64c7a8f791b ] Fix the hardware revision numbering for Qlogic ISP1020/1040 boards. HWMASK suggests that the revision number only needs four bits, this is consistent with how NetBSD does things in their ISP driver. Verified on a IPS1040B which is seen as rev 5 not as BIT_4.

[PATCH AUTOSEL 5.10 01/10] watchdog: it87_wdt: add PWRGD enable quirk for Qotom QCML04

by Sasha Levin

From: James Hilliard <james.hilliard1(a)gmail.com> [ Upstream commit 43439076383a7611300334d1357c0f8883f40816 ] For the watchdog timer to work properly on the QCML04 board we need to set PWRGD enable in the Environment Controller Configuration Registers Special Configuration Register 1 when it is not already set, this may be the case when the watchdog is not enabled from within the BIOS.
