      sh: fixed PMB mode refactoring. · a0ab3668
      Paul Mundt 提交于
      This introduces some much overdue chainsawing of the fixed PMB support.
      fixed PMB was introduced initially to work around the fact that dynamic
      PMB mode was relatively broken, though they were never intended to
      converge. The main areas where there are differences are whether the
      system is booted in 29-bit mode or 32-bit mode, and whether legacy
      mappings are to be preserved. Any system booting in true 32-bit mode will
      not care about legacy mappings, so these are roughly decoupled.
      
      Regardless of the entry point, PMB and 32BIT are directly related as far
      as the kernel is concerned, so we also switch back to having one select
      the other.
      
      With legacy mappings iterated through and applied in the initialization
      path it's now possible to finally merge the two implementations and
      permit dynamic remapping overtop of remaining entries regardless of
      whether boot mappings are crafted by hand or inherited from the boot
      loader.

      sh: Move over to dynamically allocated FPU context. · 0ea820cf
      Paul Mundt 提交于
      This follows the x86 xstate changes and implements a task_xstate slab
      cache that is dynamically sized to match one of hard FP/soft FP/FPU-less.
      
      This also tidies up and consolidates some of the SH-2A/SH-4 FPU
      fragmentation. Now fpu state restorers are commonly defined, with the
      init_fpu()/fpu_init() mess reworked to follow the x86 convention.
      The fpu_init() register initialization has been replaced by xstate setup
      followed by writing out to hardware via the standard restore path.
      
      As init_fpu() now performs a slab allocation a secondary lighterweight
      restorer is also introduced for the context switch.
      
      In the future the DSP state will be rolled in here, too.
      
      More work remains for math emulation and the SH-5 FPU, which presently
      uses its own special (UP-only) interfaces.

      sh: Abstracted SH-4A UBC support on hw-breakpoint core. · 4352fc1b
      Paul Mundt 提交于
      This is the next big chunk of hw_breakpoint support. This decouples
      the SH-4A support from the core and moves it out in to its own stub,
      following many of the conventions established with the perf events
      layering.
      
      In addition to extending SH-4A support to encapsulate the remainder
      of the UBC channels, clock framework support for handling the UBC
      interface clock is added as well, allowing for dynamic clock gating.
      
      This also fixes up a regression introduced by the SIGTRAP handling that
      broke the ksym_tracer, to the extent that the current support works well
      with all of the ksym_tracer/ptrace/kgdb. The kprobes singlestep code will
      follow in turn.
      
      With this in place, the remaining UBC variants (SH-2A and SH-4) can now
      be trivially plugged in.
