Cédric Le Goater 756c52c632 powerpc/xive: Activate StoreEOI on P10 ... StoreEOI (the capability to EOI with a store) requires load-after-store ordering in some cases to be reliable. P10 introduced a new offset for load operations to enforce correct ordering and the XIVE driver has the required support since kernel 5.8, commit b1f9be9392 ("powerpc/xive: Enforce load-after-store ordering when StoreEOI is active") Since skiboot v7, StoreEOI support is advertised on P10 with a new flag on the PowerNV platform. See skiboot commit 4bd7d84afe46 ("xive/p10: Introduce a new OPAL_XIVE_IRQ_STORE_EOI2 flag"). When detected, activate the feature.
