[PATCH 0/1] MR7904: krnl386: Fix return value for DPMI 0900h-0902h calls (Virtual Interrupt State)
According to the DPMI specification, DPMI functions 0900h-0902h related to Virtual Interrupt State has to always return state in AL register. As wine does not support disabling virtual interrupt flag, report that interrupts are always enabled (AL=1). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7904
