Peter Anvin <hpa@xxxxxxxxx> CommitDate: Wed, 17 Jun 2009 21:35:10 -0700 x86: de-assembler-ize asm/desc.h asm/desc.h is included in three assembly files, but the only macro it defines, GET_DESC_BASE, is never used. This patch removes the includes, removes the macro GET_DESC_BASE and the ASSEMBLY guard from asm/desc.h. Signed-off-by: Alexander van Heukelum <heukelum@xxxxxxxxxxx> Signed-off-by: H.
