Alex Nixon	fc0091b3c8	x86: change init_gdt to update the gdt via write_gdt, rather than a direct write. ... By writing directly, a memory access violation can occur whilst hotplugging a CPU if the entry was previously marked read-only.

Glauber Costa	e32640a2cd	x86: create smpcommon.c ... This patch creates smpcommon.c with functions that are equal between architectures. The i386-only init_gdt is ifdef'd. Note that smpcommon.o figures twice in the Makefile: this is because sub-architectures like voyager that does not use the normal smp_$(BITS) files also have to access them Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>	2008-04-17 17:40:55 +02:00
