      crypto: qat - uint8_t is not large enough for accel_id · 81b312f1
      Tadeusz Struk authored 
      accel_id has to be large enough to hold ADF_MAX_DEVICES + 1
(which is > 1025) so uint8_t is too small.

      crypto: qat - enable VF irq after guest exits ungracefully · 40c18a59
      Zeng Xin authored 
      The VF bundle interrupt is not triggered any more in
the case when guest is shut down with sample app running.
Need to clear the flag interrupt bit when restarting to fix
this irrecoverable state.

      crypto: sahara - fix debug output for 64-bit dma_addr_t · d4b98f20
      Arnd Bergmann authored 
      The sahara_dump_descriptors and sahara_dump_links functions attempt
to print a dma_addr_t value with a 0x%08x format string, which
produces a warning when dma_addr_t is 64-bit wide:

drivers/crypto/sahara.c:419:120: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=]

This changes the code to use the %pad format string that is meant
for dma_addr_t, which avoids the warning and gives us the correct
output in all configurations.

      crypto: sahara - fix 64-bit dma_addr_t compilation · 75d3f811
      Arnd Bergmann authored 
      The sahara hardware uses DMA descriptors with 32-bit addresses, but
dma_addr_t is variable size depending on whether we want to support
any devices that use 64-bit DMA addresses in hardware.
This means that the definition of the DMA descriptor structure is wrong,
and we helpfully get a compiler warning about them too:

drivers/crypto/sahara.c:423:372: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=]

This changes the definition of the sahara_hw_desc and sahara_hw_link
structures to only contain fixed-length members, which is required
to make the driver work on ARM LPAE mode, and avoids most of the
gcc warnings we get.

      The drbg_state_ops structures are never modified, so declare them as const.

Done with the help of Coccinelle.
