The patch titled
i386 bootioremap / kexec fix
has been removed from the -mm tree. Its filename is
i386-bootioremap--kexec-fix.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
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.
[ Keith says this is applicable to 2.6.16 and 2.6.17 as well ]
