      sparc64: Fix memory corruption when THP is enabled · 76811263
      Nitin Gupta authored
      The memory corruption was happening due to incorrect
      TLB/TSB flushing of hugepages.

      sparc64: Fix kernel panic due to erroneous #ifdef surrounding pmd_write() · 9ae34dbd
      Tom Hromatka authored
      This commit moves sparc64's prototype of pmd_write() outside
      of the CONFIG_TRANSPARENT_HUGEPAGE ifdef.
      
      In 2013, commit a7b9403f ("sparc64: Encode huge PMDs using PTE
      encoding.") exposed a path where pmd_write() could be called without
      CONFIG_TRANSPARENT_HUGEPAGE defined.  This can result in the panic below.
      
      The diff is awkward to read, but the changes are straightforward.
      pmd_write() was moved outside of #ifdef CONFIG_TRANSPARENT_HUGEPAGE.
      Also, __HAVE_ARCH_PMD_WRITE was defined.

      arch/sparc: Avoid DCTI Couples · 0ae2d26f
      Babu Moger authored
      Avoid un-intended DCTI Couples. Use of DCTI couples is deprecated.
      Also address the "Programming Note" for optimal performance.
      
      Here is the complete text from Oracle SPARC Architecture Specs.
      
      6.3.4.7 DCTI Couples
      "A delayed control transfer instruction (DCTI) in the delay slot of
      another DCTI is referred to as a “DCTI couple”. The use of DCTI couples
      is deprecated in the Oracle SPARC Architecture; no new software should
      place a DCTI in the delay slot of another DCTI, because on future Oracle
      SPARC Architecture implementations DCTI couples may execute either
      slowly or differently than the programmer assumes it will.
      
      SPARC V8 and SPARC V9 Compatibility Note
      The SPARC V8 architecture left behavior undefined for a DCTI couple. The
      SPARC V9 architecture defined behavior in that case, but as of
      UltraSPARC Architecture 2005, use of DCTI couples was deprecated.
      Software should not expect high performance from DCTI couples, and
      performance of DCTI couples should be expected to decline further in
      future processors.
      
      Programming Note
      As noted in TABLE 6-5 on page 115, an annulled branch-always
      (branch-always with a = 1) instruction is not architecturally a DCTI.
      However, since not all implementations make that distinction, for
      optimal performance, a DCTI should not be placed in the instruction word
      immediately following an annulled branch-always instruction (BA,A or
      BPA,A)."

      sparc64: kern_addr_valid regression · adfae8a5
      bob picco authored
      I encountered this bug when using /proc/kcore to examine the kernel. Plus a
      coworker inquired about debugging tools. We computed pa but did
      not use it during the maximum physical address bits test. Instead we used
      the identity mapped virtual address which will always fail this test.
      
      I believe the defect came in here:
      [bpicco@zareason linus.git]$ git describe --contains bb4e6e85
      v3.18-rc1~87^2~4
