treewide: remove SPDX "WITH Linux-syscall-note" from kernel-space headers again

2019-07-25T09:05:10Z

The "WITH Linux-syscall-note" exception exists for headers exported to user space. It is strange to add it to non-exported headers. Commit 687a3e4d8e61 ("treewide: remove SPDX "WITH Linux-syscall-note" from kernel-space headers") did cleanups some months ago, but it looks like we need to do this periodically. This patch was generated by the following script: git grep -l -e Linux-syscall-note \ -- :*.h :^arch/*/include/uapi/asm/*.h :^include/uapi/ :^tools | while read file do sed -i -e 's/($GPL-[^[:space:]]*$ WITH Linux-syscall-note)/\1/g' \ -e 's/ WITH Linux-syscall-note//g' $file done I did not commit drivers/staging/android/uapi/ion.h . This header is not currently exported, but somebody may plan to move it to include/uapi/ when the time comes. I am not sure. Anyway, it will be better to check the license inconsistency in drivers/staging/android/uapi/. Signed-off-by: Masahiro Yamada Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

vfio-mdev/samples: Use u8 instead of char for handle functions

Clang warns: samples/vfio-mdev/mtty.c:592:39: warning: implicit conversion from 'int' to 'char' changes value from 162 to -94 [-Wconstant-conversion] *buf = UART_MSR_DSR | UART_MSR_DDSR | UART_MSR_DCD; ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~ 1 warning generated. Turns out that all uses of buf in this function ultimately end up stored or cast to an unsigned type. Just use u8, which has the same number of bits but can store this larger number so Clang no longer warns. Signed-off-by: Nathan Chancellor Signed-off-by: Alex Williamson
