https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-2.6.25.y2008-03-26T10:02:47Zsh: Fix occasional FPU register corruption under preempt.2008-03-26T10:02:47ZPaul Mundt2008-03-26T10:02:47Zurn:sha1:9bbafce2eec190ef7e44b0eb1095ba17ce6ad3af
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.

sh: GUSA atomic rollback support.2008-01-28T04:18:58ZStuart Menefy2007-11-30T07:12:36Zurn:sha1:1efe4ce3ca126da77e450d5a83f7201949d76f62
This implements kernel-level atomic rollback built on top of gUSA,
as an alternative non-IRQ based atomicity method. This is generally
a faster method for platforms that are lacking the LL/SC pairs that
SH-4A and later use, and is only supportable on legacy cores.
