* x86: fixes some bugs about EFI memory map handlingHuang, Ying2008-01-301-15/+0
| | | | | | | | | | | | | | | | | | This patch fixes some bugs of EFI memory handing code. - On x86_64, it is possible that EFI memory map can not be mapped via identity map, so efi_map_memmap is removed, just use early_ioremap. - On i386, the EFI memory map mapping take effect cross paging_init, so it is not necessary to use efi_map_memmap. - EFI memory map is unmapped in efi_enter_virtual_mode to avoid early_ioremap leak.

* x86 32-bit boot: rename bt_ioremap() to early_ioremap()Huang, Ying2008-01-301-1/+1
| | | | | | | | | | | This patch renames bt_ioremap to early_ioremap, which is used in x86_64. This makes it easier to merge i386 and x86_64 usage.

* x86: 32-bit EFI runtime service support: fixes in sync with 64-bit supportHuang, Ying2008-01-301-20/+5
| | | | | | | | | | | | | | | | | | | | | | 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.

* x86 boot: use E820 memory map on EFI 32 platformHuang, Ying2008-01-301-150/+0
| | | | | | | | | | | | Because the EFI memory map are converted to e820 memory map in bootloader, the EFI memory map handling code is removed to clean up.

* x86: unify struct desc_ptrGlauber de Oliveira Costa2008-01-301-2/+2
| | | | | | | | | | | | | | This patch unifies struct desc_ptr between i386 and x86_64. They can be expressed in the exact same way in C code, only having to change the name of one of them. As Xgt_desc_struct is ugly and big, this is the one that goes away. There's also a padding field in i386, but it is not really needed in the C structure definition.

* kexec: add BSS to resource treeBernhard Walle2007-10-221-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | Add the BSS to the resource tree just as kernel text and kernel data are in the resource tree. The main reason behind this is to avoid crashkernel reservation in that area. While it's not strictly necessary to have the BSS in the resource tree (the actual collision detection is done in the reserve_bootmem() function before), the usage of the BSS resource should be presented to the user in /proc/iomem just as Kernel data and Kernel code. Note: The patch currently is only implemented for x86 and ia64 (because efi_initialize_iomem_resources() has the same signature on i386 and ia64).
