| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that IRQ2 is never made available to the I/O APIC, there is no need to special-case it and mask as a workaround for broken systems.

The test that generates CONFIG_AS_CFI does not have anything x86_64-specific, and right now, checking V=1 builds shows me that the flags is there anyway, although unused.

Taking a look at this portion of arch/x86/kernel/process_64.o revealed this crutial difference: | good: 99c: 8c e0 mov %fs,%eax | 99e: 89 45 cc mov %eax,-0x34(%rbp) | | bad: 99c: 8c 65 cc mov %fs,-0x34(%rbp) which is due to: | unsigned fsindex; | - asm volatile("movl %%fs,%0" : "=r" (fsindex)); | + savesegment(fs, fsindex); savesegment() is implemented as: #define savesegment(seg, value) \ asm("mov %%" #seg ",%0":"=rm" (value) : : "memory") note the "m" modifier - it allows GCC to generate the segment move into a memory operand as well. But regarding segment operands there's a subtle detail in the x86 instruction set: the above 16-bit moves are zero-extend, but only if it goes to a register. If it goes to a memory operand, -0x34(%rbp) in the above case, there's no zero-extend to 32-bit and the instruction will only save 16 bits instead of the intended 32-bit. The other 16 bits is random data - which can cause problems when that value is used later on. The solution is to only allow segment operands to go to registers. This fix allows my test-system to boot up without crashing. Signed-off-by: Ingo Molnar <mingo@elte.hu>

Note that for X86_64, CONFIG_X86_WP_WORKS_OK will always be defined, so the #else part will never be even compiled in. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: H.
