From 0a1e8869f453ceda121a1ff8d6c4380832377be7 Mon Sep 17 00:00:00 2001 From: Cyrill Gorcunov Date: Wed, 28 Jan 2009 23:21:25 +0300 Subject: x86: trampoline_64.S - use predefined constants with simplification Impact: cleanup We may use macros from processor-flags.h instead of hardcoding bits. Actually it's not direct mapping of old instructions with new ones -- BTS does change CF flag while MOV does not. But i didn't find any dependency on CF in this code.

One is used to jump from kernel virtual address to identity map address, the other is used to map all physical memory. In fact, on x86_64, there is no conflict between kernel virtual address space and physical memory space, so just one page table is sufficient. The page table pages used to map control page are dynamically allocated to save memory if kexec image is not loaded. ASM code used to map control page is replaced by C code too.

This can cause problems - for example the hypothetical case when some spurious access still references it. v2: remove prev_map and prev_size in __apci_map_table v3: let acpi_os_unmap_memory() call early_iounmap too, so remove extral calling to early_acpi_os_unmap_memory v4: fix typo in one acpi_get_table_with_size calling Signed-off-by: Yinghai Lu Acked-by: Len Brown Signed-off-by: Ingo Molnar
