From: Sai Praneeth This patch set is an outcome of the discussion at https://lkml.org/lkml/2017/8/21/607 Presently, efi_runtime_services() are executed by firmware in process context. To execute efi_runtime_service(), kernel switches the page directory from

[PATCH V2 1/3] x86/efi: Call efi_delete_dummy_variable() during efi subsystem initialization

From: Sai Praneeth Invoking efi_runtime_services() through efi_workqueue means all accesses to efi_runtime_services() should be done after efi_rts_wq has been created. efi_delete_dummy_variable() calls set_variable(), hence efi_delete_dummy_variable() should be

[PATCH V2 2/3] efi: Introduce efi_rts_workqueue and some infrastructure to invoke all efi_runtime_services()

From: Sai Praneeth When a process requests the kernel to execute any efi_runtime_service(), the requested efi_runtime_service (represented as an identifier) and its arguments are packed into a struct named efi_runtime_work and queued onto work queue named
