2008-02-20Remove empty file remnants that were left in the tree by mistakeLinus Torvalds1-1/+0
Noted by various people (Sam, Jeff, Roland..) Commit 58b7983d15a422d9616bdc4e245d5c31dfaefbe2 intended to remove the xfs "Makefile-linux-2.6" file, but it was mistakenly still left in the tree as a empty file, and would cause git to correctly complain about a tracked file being removed after a "make distclean" (which removes empty files as garbage). And the asm-x86/desc_64.h file was supposed to be removed by commit c81c6ca45a69478c7877b729af1942d2b80ef582, but instead stayed around containing just a single newline. Get rid of them both properly. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-01-30x86: unify set_tss_descGlauber de Oliveira Costa1-33/+0
This patch unifies the set_tss_desc between i386 and x86_64, which can now have a common implementation. After the old functions are removed from desc_{32,64}.h, nothing important is left, and the files can be removed.

2008-01-30x86: move _set_gate and its users to a common locationGlauber de Oliveira Costa1-45/+0
This patch moves _set_gate and its users to desc.h. We can now use common code for x86_64 and i386. [ mingo@elte.hu: set_system_gate() fixes for nasty crashes. ] Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-01-30x86: unify paravirt pieces of descriptor handlingGlauber de Oliveira Costa1-93/+11
With the types used to access descriptors in x86_64 and i386 now being the same, the code that effectively handles them can now be easily shared. This patch moves the paravirt part of desc_32.h into desc.h, and then, we get paravirt support in x86_64 for free.

2008-01-30x86: modify get_desc_baseGlauber de Oliveira Costa1-9/+0
This patch makes get_desc_base() receive a struct desc_struct, and then uses its internal fields to compute the base address. This is done at both i386 and x86_64, and then it is moved to common header Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-01-30x86: use the same data type for tls_array.Glauber de Oliveira Costa1-1/+1
This patch changes the type of tls_array in x86_64 to a desc_struct. Now, both i386 and x86_64 tls_array have the same type, and code accessing it can be shared.

2008-01-30x86: unify non-paravirt parts of desc.hGlauber de Oliveira Costa1-45/+10
This patch unifies the non-paravirt part of desc_{32,64}.h into desc.h. Most of it, is simply common code, that is moved to the shared header. The only exception is the set_ldt_desc in desc_64.h, which is changed - included its name - to accomodate for the way the ldt is set up in i386. Also, constant definitions used in desc_32.h are moved to desc_defs.h Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2008-01-30x86: introduce fill_ldtGlauber de Oliveira Costa1-17/+0
This patch introduces fill_ldt(), which populates a ldt descriptor from a user_desc in once, instead of relying in the LDT_entry_a and LDT_entry_b macros Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2008-01-30x86: get_desc_baseRoland McGrath1-0/+10
This defines the get_desc_base function in asm-x86/desc_64.h to match the one in desc_32.h. If these two files ever get merged together, this function could be the same in both.
