      ARM: OMAP AM33xx: powerdomains: add AM335x support · 3f0ea764
      Vaibhav Hiremath authored
      Add offset & mask fields to struct powerdomain
      
      In case of AM33xx family of devices, there is no consistency between
      PWRSTCTRL & PWRSTST register offsers in PRM space, for example -
      
      PRM_XXX           PWRSTCTRL     PWRSTST
      =======================================
      PRM_PER_MOD:      0x0C,         0x08
      PRM_WKUP_MOD:     0x04,         0x08
      PRM_MPU_MOD:      0x00,         0x04
      PRM_DEVICE_MOD:   NA,           NA
      
      And also, there is no consistency between bit-offsets inside
      PWRSTCTRL & PWRSTST register, for example -
      
      PRM_XXX           LOGICRET  MEMON  MEMRET
      =======================================
      GFX_PWRCTRL:      2,        17,    6
      PER_PWRCTRL:      3,        25,    29
      MPU_PWRCTRL:      2,        18,    22
      WKUP_PWRCTRL:     3,        NA,    NA
      
      This means, we need to maintain and pass on all this information
      in powerdomain handle; so adding fields for,
         - PWRSTCTRL/ST register offset
         - Logic retention state mask
         - mem_on/ret/pwrst/retst mask
      
      Currently, this fields is only applicable and used for AM33XX devices.

      ARM: OMAP AM33xx: CM: Introduce AM33xx CM APIs and register level details · f969a6dc
      Vaibhav Hiremath authored
      As far as PRM/CM/PRCM modules are concerned, AM33XX device is
      different than OMAP3 and OMAP4 architectures; so similar to
      PRM implementation, handle AM33XX CM separately.
      
      This patch introduces AM33XX CM module low-level api's, used and
      required by omap clockdomain and hwmod framework.
      
      Please note that cm-regbits-33xx.h (register bit field offset)
      and cm33xx.h (register addr offset) files are mostly auto generated.

      x86, x32, ptrace: Remove PTRACE_ARCH_PRCTL for x32 · bad1a753
      H.J. Lu authored
      When I added x32 ptrace to 3.4 kernel, I also include PTRACE_ARCH_PRCTL
      support for x32 GDB  For ARCH_GET_FS/GS, it takes a pointer to int64.  But
      at user level, ARCH_GET_FS/GS takes a pointer to int32.  So I have to add
      x32 ptrace to glibc to handle it with a temporary int64 passed to kernel and
      copy it back to GDB as int32.  Roland suggested that PTRACE_ARCH_PRCTL
      is obsolete and x32 GDB should use fs_base and gs_base fields of
      user_regs_struct instead.
      
      Accordingly, remove PTRACE_ARCH_PRCTL completely from the x32 code to
      avoid possible memory overrun when pointer to int32 is passed to
      kernel.

      The 'mtd_writev' interface calls the function assigned
      to the '_write' field of a given mtd device if that is
      not NULL. The block2mtd driver sets the '_writev' field
      to the 'mtd_writev' function itself and thus causes a
      endless loop.
      
      This is caused by 1dbebd32
      (mtd: harmonize mtd_writev usage).
      
      Remove the assignment from the block2mtd driver to fix the
      issue.

      mtd: gpmi-nand: define ecc.strength · 5636ce0f
      Marek Vasut authored
      Fix an issue which was introduced by the recent addition of ecc.strength.
      
      The ecc.strength wasn't set in gpmi-nand, resulting in the following crash:
