Remove attribute((weak)) from sys_pipe/sys_pipe2

2009-01-18T18:43:51Z

commit 1134723e96f6e2abcf8bfd7a2d1c96fcc323ef35 upstream. Remove __attribute__((weak)) from common code sys_pipe implemantation. IA64, ALPHA, SUPERH (32bit) and SPARC (32bit) have own implemantations with the same name. Just rename them. For sys_pipe2 there is no architecture specific implementation.

sh: Disable GENERIC_HARDIRQS_NO__DO_IRQ for unconverted platforms.

Presently limited to Cayman, Dreamcast, Microdev, and SystemH 7751. Re-enable it for everyone once these have been fixed up. Signed-off-by: Paul Mundt

serial: sh-sci: Reorder the SCxTDR write after the TDxE clear.

2008-11-13T08:46:06Z

Under qemu there is a race between the TDxE read-and-clear and the SCxTDR write. While on hardware it can be gauranteed that the read-and-clear will happen prior to the character being written out, no such assumption can be made under emulation. As this path happens with IRQs off and the hardware itself doesn't care about the ordering, move the SCxTDR write until after the read-and-clear.

sh: __copy_user function can corrupt the stack in case of exception

2008-11-13T08:40:30Z

The __copy_user function can corrupt the stack in the case of a non-trivial length of data, and either of the first two move instructions cause an exception. This is because the fixup for these two instructions is mapped to the no_pop case, but these instructions execute after the stack is pushed. This change creates an explicit NO_POP exception mapping macro, and uses it for the two instructions executed in the trivial case where no stack pushes occur.

sh: Fixed the TMU0 reload value on resume

2008-11-13T08:40:30Z

This patch fixes the TMU0 interrupt frequency on suspend/resume. During the resume the kernel reprograms the TMU0.ClockEvent mode but if the mode is periodic than the TMU0.TCOR is updated with a random wrong value without taking care latest valid saved value. There was no problem with No_HZ system where TMU0.TCOR isn't used. Signed-off-by: Francesco M. Virlinzi Signed-off-by: Stuart Menefy Signed-off-by: Paul Mundt

sh: Provide a sane valid_phys_addr_range() to prevent TLB reset with PMB.

2008-11-12T03:53:48Z

With the PMB enabled, only P1SEG and up are covered by the PMB mappings, meaning that situations where out-of-bounds physical addresses are read from will lead to TLB reset after the PMB miss, allowing for use cases like dd if=/dev/mem to reset the TLB. Fix this up to make sure the reference is between __MEMORY_START (phys) and __pa(high_memory). This is coherent across all variants of sh/sh64 with and without MMU, though the PMB bug itself is only applicable to SH-4A parts. Reported-by: Hideo Saito Signed-off-by: Paul Mundt
