From 8b2cb7a8f531d6ca72a8aff873b9bb1c6b3122ba Mon Sep 17 00:00:00 2001 From: "Huang, Ying" Date: Wed, 30 Jan 2008 13:32:11 +0100 Subject: x86: 32-bit EFI runtime service support: fixes in sync with 64-bit support support according to fixes of x86_64 support. - Delete efi_rt_lock because it is used during system early boot, before SMP is initialized. - Change local_flush_tlb() to __flush_tlb_all() to flush global page mapping. - Clean up includes. - Revise Kconfig description. - Enable noefi kernel parameter on i386.
