linux.git/arch/sh/kernel/cpu/sh4, branch v2.6.25 Linux kernel source tree sh: Fix occasional FPU register corruption under preempt. 2008-03-26T10:02:47+00:00 Paul Mundt lethal@linux-sh.org 2008-03-26T10:02:47+00:00 9bbafce2eec190ef7e44b0eb1095ba17ce6ad3af Presently with preempt enabled there's the possibility to be preempted after the TIF_USEDFPU test and the register save, leading to bogus state post-__switch_to(). Use an explicit preempt_disable()/enable() pair around unlazy_fpu()/clear_fpu() to avoid this. Follows the x86 change.

serial: Move asm-sh/sci.h to linux/serial_sci.h. 2008-02-26T05:52:45+00:00 Paul Mundt lethal@linux-sh.org 2008-02-26T05:52:45+00:00 96de1a8f0275bd67f243833e7088baced518f873 This header is needed on other architectures as well (namely h8300), which currently fails to build without this in place. Rather than duplicating the port definition completely there, just move this to a common location instead. This should get h8300 working again for 2.6.25, in addition to the changes already pushed by Sato-san in -rc2. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
