Subject: i386 bootioremap / kexec fix
From: keith mannthey <kmannth@xxxxxxxxxx>
With CONFIG_PHYSICAL_START set to a non default values the i386
boot_ioremap code calculated its pte index wrong and users of boot_ioremap
have their areas incorrectly mapped (for me SRAT table not mapped during
early boot). This patch removes the addr < BOOT_PTE_PTRS constraint.
