Henry Wang e155741ec4 drivers/xen: Improve the late XenStore init protocol ... [ Upstream commit a3607581cd ] Currently, the late XenStore init protocol is only triggered properly for the case that HVM_PARAM_STORE_PFN is ~0ULL (invalid). For the case that XenStore interface is allocated but not ready (the connection status is not XENSTORE_CONNECTED), Linux should also wait until the XenStore is set up properly. Introduce a macro to describe the XenStore interface is ready, use it in xenbus_probe_initcall() to select the code path of doing the late XenStore init protocol or not. Since now we have more than one condition for XenStore late init, rework the check in xenbus_probe() for the free_irq(). Take the opportunity to enhance the check of the allocated XenStore interface can be properly mapped, and return error early if the memremap() fails.
