x86: change init_gdt to update the gdt via write_gdt, rather than a direct write.

2008-08-15T17:16:05Z

By writing directly, a memory access violation can occur whilst hotplugging a CPU if the entry was previously marked read-only. Signed-off-by: Alex Nixon Cc: Jeremy Fitzhardinge Signed-off-by: Ingo Molnar

x86: convert to generic helpers for IPI function calls

2008-06-26T09:21:54Z

This converts x86, x86-64, and xen to use the new helpers for smp_call_function() and friends, and adds support for smp_call_function_single(). Acked-by: Ingo Molnar Acked-by: Jeremy Fitzhardinge Signed-off-by: Jens Axboe

x86: create smpcommon.c

2008-04-17T15:40:55Z

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 Signed-off-by: Ingo Molnar
