Turn PBVM page table entries into PTEs so that they can be inserted into the TLB as-is.
While here, have ia64_platform_alloc() return ~0UL on failure.

Use the new arch_loadaddr I/F to align ELF objects to PBVM page boundaries. For good measure, align all other objects to cache lines boundaries.
Use the new arch_loadseg I/F to keep track of kernel text and data so that we can wire as much of it as is possible. It is the responsibility of the kernel to link critical (read IVT related) code and data at the front of the respective segment so that it's covered by TRs before the kernel has a chance to add more translations.
Use a better way of determining whether we're loading a legacy kernel or not. We can't check for the presence of the PBVM page table, because we may have unloaded that kernel and loaded an older (legacy) kernel after that. Simply use the latest load address for it.

MFaltix: Add support for Pre-Boot Virtual Memory (PBVM) to the loader.
PBVM allows us to link the kernel at a fixed virtual address without having to make any assumptions about the physical memory layout. On the SGI Altix 350 for example, there's no usuable physical memory below 192GB. Also, the PBVM allows us to control better where we're going to physically load the kernel and its modules so that we can make sure we load the kernel in memory that's close to the BSP.
The PBVM is managed by a simple page table. The minimum size of the page table is 4KB (EFI page size) and the maximum is currently set to 1MB. A page in the PBVM is 64KB, as that's the maximum alignment one can specify in a linker script. The bottom line is that PBVM is between 64KB and 8GB in size.
The loader maps the PBVM page table at a fixed virtual address and using a single translations. The PBVM itself is also mapped using a single translation for a maximum of 32MB.
While here, increase the heap in the EFI loader from 512KB to 2MB and set the stage for supporting relocatable modules.

Major rework of the ia64 loaders. The two primary objectives are: 1. Make libefi portable by removing ia64 specific code and build it on i386 and amd64 by default to prevent regressions. These changes include fixes and improvements over previous code to establish or improve APIs where none existed or when the amount of kluging was unacceptably high. 2. Increase the amount of sharing between the efi and ski loaders to improve maintainability of the loaders and simplify making changes to the loader-kernel handshaking in the future.
The version of the efi and ski loaders are now both changed to 1.2 as user visible improvements and changes have been made.

o Introduce efimd_va2pa() to translate addresses in efi_copy{in|out}() and efi_readin(). This removes MD code from copy.c. o Don't unconditionally add pal.S to SRCS. It's specific to ia64.

o Remove namespace pollution from param.h: - Don't include ia64_cpu.h and cpu.h - Guard definitions by _NO_NAMESPACE_POLLUTION - Move definition of KERNBASE to vmparam.h
o Move definitions of IA64_RR_{BASE|MASK} to vmparam.h o Move definitions of IA64_PHYS_TO_RR{6|7} to vmparam.h
o While here, remove some left-over Alpha references.

Make this do the right thing (mostly). We should still reserve the pages that the kernel loads into using the EFI AllocatePages call.
