      iov_iter: fix build issue due to possible type mis-match · 1c27f1fc
      Linus Torvalds authored
      Commit 6c776766 ("iov_iter: Fix iter_xarray_get_pages{,_alloc}()")
      introduced a problem on some 32-bit architectures (at least arm, xtensa,
      csky,sparc and mips), that have a 'size_t' that is 'unsigned int'.
      
      The reason is that we now do
      
          min(nr * PAGE_SIZE - offset, maxsize);
      
      where 'nr' and 'offset' and both 'unsigned int', and PAGE_SIZE is
      'unsigned long'.  As a result, the normal C type rules means that the
      first argument to 'min()' ends up being 'unsigned long'.
      
      In contrast, 'maxsize' is of type 'size_t'.
      
      Now, 'size_t' and 'unsigned long' are always the same physical type in
      the kernel, so you'd think this doesn't matter, and from an actual
      arithmetic standpoint it doesn't.
      
      But on 32-bit architectures 'size_t' is commonly 'unsigned int', even if
      it could also be 'unsigned long'.  In that situation, both are unsigned
      32-bit types, but they are not the *same* type.
      
      And as a result 'min()' will complain about the distinct types (ignore
      the "pointer types" part of the error message: that's an artifact of the
      way we have made 'min()' check types for being the same):
      
        lib/iov_iter.c: In function 'iter_xarray_get_pages':
        include/linux/minmax.h:20:35: error: comparison of distinct pointer types lacks a cast [-Werror]
           20 |         (!!(sizeof((typeof(x) *)1 == (typeof(y) *)1)))
              |                                   ^~
        lib/iov_iter.c:1464:16: note: in expansion of macro 'min'
         1464 |         return min(nr * PAGE_SIZE - offset, maxsize);
              |                ^~~
      
      This was not visible on 64-bit architectures (where we always define
      'size_t' to be 'unsigned long').
      
      Force these cases to use 'min_t(size_t, x, y)' to make the type explicit
      and avoid the issue.
      
      [ Nit-picky note: technically 'size_t' doesn't have to match 'unsigned
        long' arithmetically. We've certainly historically seen environments
        with 16-bit address spaces and 32-bit 'unsigned long'.
      
        Similarly, even in 64-bit modern environments, 'size_t' could be its
        own type distinct from 'unsigned long', even if it were arithmetically
        identical.
      
        So the above type commentary is only really descriptive of the kernel
        environment, not some kind of universal truth for the kinds of wild
        and crazy situations that are allowed by the C standard ]

      wireguard: selftests: use maximum cpu features and allow rng seeding · 17b0128a
      Jason A. Donenfeld authored
      By forcing the maximum CPU that QEMU has available, we expose additional
      capabilities, such as the RNDR instruction, which increases test
      coverage. This then allows the CI to skip the fake seeding step in some
      cases. Also enable STRICT_KERNEL_RWX to catch issues related to early
      jump labels when the RNG is initialized at boot.

      scripts/gdb: change kernel config dumping method · 1f7a6cf6
      Kuan-Ying Lee authored
      MAGIC_START("IKCFG_ST") and MAGIC_END("IKCFG_ED") are moved out
      from the kernel_config_data variable.
      
      Thus, we parse kernel_config_data directly instead of considering
      offset of MAGIC_START and MAGIC_END.

      Vincent Whitchurch authored
      Call virtio_device_ready() to make this driver work after commit
      b4ec69d7e09 ("virtio: harden vring IRQ"), since the driver uses the
      virtqueues in the probe function.  (The virtio core sets the device
      ready when probe returns.)
