x86: Delete non-required instances of include

2014-01-07T05:25:18Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

x86, realmode: Pointer walk cleanups, pull out invariant use of __pa()

2013-12-19T00:07:53Z

The pointer arithmetic in this function was really bizarre, where in fact all we really wanted was a simple pointer array walk. Use the much more idiomatic construction for that (*ptr++). Factor an invariant use of __pa() out of the relocation loop. At least on 64 bits it seems gcc isn't capable of doing that automatically. Change the scope of a couple of variables to make it extra obvious that they are extremely local temp variables. Signed-off-by: H.

x86, build: Pass in additional -mno-mmx, -mno-sse options

2013-12-09T23:52:39Z

In checkin 5551a34e5aea x86-64, build: Always pass in -mno-sse we unconditionally added -mno-sse to the main build, to keep newer compilers from generating SSE instructions from autovectorization. However, this did not extend to the special environments (arch/x86/boot, arch/x86/boot/compressed, and arch/x86/realmode/rm). Add -mno-sse to the compiler command line for these environments, and add -mno-mmx to all the environments as well, as we don't want a compiler to generate MMX code either. This patch also removes a $(cc-option) call for -m32, since we have long since stopped supporting compilers too old for the -m32 option, and in fact hardcode it in other places in the Makefiles.

x86, realmode: Separate real_mode reserve and setup

2013-01-29T23:13:24Z

After we switch to use #PF handler help to set page table, init_level4_pgt will only have entries set after init_mem_mapping(). We need to move copying init_level4_pgt to trampoline_pgd after that. So split reserve and setup, and move the setup after init_mem_mapping() Signed-off-by: Yinghai Lu Link: http://lkml.kernel.org/r/1359058816-7615-11-git-send-email-yinghai@kernel.org Cc: Jarkko Sakkinen Acked-by: Jarkko Sakkinen Signed-off-by: H.

x86, 64bit, realmode: Use init_level4_pgt to set trampoline_pgd directly

2013-01-29T23:12:30Z

with #PF handler way to set early page table, level3_ident will go away with 64bit native path. So just use entries in init_level4_pgt to set them in trampoline_pgd.
