      kconfig: Add support for -Wimplicit-fallthrough · dee2b702
      Gustavo A. R. Silva authored
      Add Kconfig support for -Wimplicit-fallthrough for both GCC and Clang.
      
      The compiler option is under configuration CC_IMPLICIT_FALLTHROUGH,
      which is enabled by default.
      
      Special thanks to Nathan Chancellor who fixed the Clang bug[1][2]. This
      bugfix only appears in Clang 14.0.0, so older versions still contain
      the bug and -Wimplicit-fallthrough won't be enabled for them, for now.
      
      This concludes a long journey and now we are finally getting rid
      of the unintentional fallthrough bug-class in the kernel, entirely. :)

      Pull xfs cleanups from Darrick Wong:
       "The most 'exciting' aspect of this branch is that the xfsprogs
        maintainer and I have worked through the last of the code
        discrepancies between kernel and userspace libxfs such that there are
        no code differences between the two except for #includes.
      
        IOWs, diff suffices to demonstrate that the userspace tools behave the
        same as the kernel, and kernel-only bits are clearly marked in the
        /kernel/ source code instead of just the userspace source.
      
        Summary:
      
         - Clean up open-coded swap() calls.
      
         - A little bit of #ifdef golf to complete the reunification of the
           kernel and userspace libxfs source code"

      Pull irq fixes from Thomas Gleixner:
       "A set of fixes for the interrupt subsystem
      
        Core code:
      
         - A regression fix for the Open Firmware interrupt mapping code where
           a interrupt controller property in a node caused a map property in
           the same node to be ignored.
      
        Interrupt chip drivers:
      
         - Workaround a limitation in SiFive PLIC interrupt chip which
           silently ignores an EOI when the interrupt line is masked.
      
         - Provide the missing mask/unmask implementation for the CSKY MP
           interrupt controller.
      
        PCI/MSI:
      
         - Prevent a use after free when PCI/MSI interrupts are released by
           destroying the sysfs entries before freeing the memory which is
           accessed in the sysfs show() function.
      
         - Implement a mask quirk for the Nvidia ION AHCI chip which does not
           advertise masking capability despite implementing it. Even worse
           the chip comes out of reset with all MSI entries masked, which due
           to the missing masking capability never get unmasked.
      
         - Move the check which prevents accessing the MSI[X] masking for XEN
           back into the low level accessors. The recent consolidation missed
           that these accessors can be invoked from places which do not have
           that check which broke XEN. Move them back to he original place
           instead of sprinkling tons of these checks all over the code"
