      x86: remove pointless uaccess_32.h complexity · 5b09c3ed
      Linus Torvalds authored
      I'm looking at trying to possibly merge the 32-bit and 64-bit versions
      of the x86 uaccess.h implementation, but first this needs to be cleaned
      up.
      
      For example, the 32-bit version of "__copy_to_user_inatomic()" is mostly
      the special cases for the constant size, and it's actually never
      relevant.  Every user except for one aren't actually using a constant
      size anyway, and the one user that uses it is better off just using
      __put_user() instead.
      
      So get rid of the unnecessary complexity.
      
      [ The same cleanup should likely happen to __copy_from_user_inatomic()
        as well, but that one has a lot more users that I need to take a look
        at first ]

       "In this round, as Ted pointed out, fscrypto allows one more key prefix
        given by filesystem to resolve backward compatibility issues.  Other
        than that, we've fixed several error handling cases by introducing
        a fault injection facility.  We've also achieved performance
        improvement in some workloads as well as a bunch of bug fixes.
      
        Summary:
      
        Enhancements:
         - fs-specific prefix for fscrypto
         - fault injection facility
         - expose validity bitmaps for user to be aware of fragmentation
         - fallocate/rm/preallocation speed up
         - use percpu counters
      
        Bug fixes:
         - some inline_dentry/inline_data bugs
         - error handling for atomic/volatile/orphan inodes
         - recover broken superblock"

      x86 isa: add back X86_32 dependency on CONFIG_ISA · 51e68d05
      Linus Torvalds authored
      Commit b3c1be1b ("base: isa: Remove X86_32 dependency") made ISA
      support available on x86-64 too.  That's not right - while there are
      some LPC-style devices that might be useful still and be based on
      ISA-like IP blocks, that is *not* an excuse to try to enable any random
      legacy drivers.
      
      Such drivers should be individually enabled and made to perhaps depend
      on ISA_DMA_API instead (which we have continued to support on x86-64).
      Or we could add another "ISA_XYZ_API" that we support that doesn't
      enable random old drivers that aren't even 64-bit clean nor do we have
      any test coverage for.
      
      Turning off ISA will now also turn off some drivers that have been
      marked as depending on it as part of this series, and that used to work
      on modern platforms.
      
      See for example commits ad7afc38..cc736607, which may also need
      to be reverted.
      
      This commit means that the warnings that came in due to enabling ISA
      widely are now gone again.

      Mylène Josserand authored
      The RTC RV3029 handles different types of alarms : seconds, minutes, ...
      These alarms can be enabled or disabled individually using an AE_x bit
      which is the last bit (BIT(7)) on each alarm registers.
      
      To prepare the alarm IRQ support, the current code enables all the alarm
      types by setting each AE_x to 1.
      It also fixes others alarms issues :
         - month and weekday errors : it was performing -1 instead of +1.
         - wrong use of bit mask with bin2bcd
