s390: use __u{16,32,64} instead of uint{16,32,64}_t in uapi header
When CONFIG_UAPI_HEADER_TEST=y, exported headers are compile-tested to make sure they can be included from user-space. Currently, zcrypt.h is excluded from the test coverage. To make it join the compile-test, we need to fix the build errors attached below. For a case like this, we decided to use __u{8,16,32,64} variable types in this discussion: https://lkml.org/lkml/2019/6/5/18 Build log: CC usr/include/asm/zcrypt.h.s In file included from <command-line>:32:0: ./usr/include/asm/zcrypt.h:163:2: error: unknown type name ‘uint16_t’ uint16_t cprb_len; ^~~~~~~~ ./usr/include/asm/zcrypt.h:168:2: error: unknown type name ‘uint32_t’ uint32_t source_id; ^~~~~~~~ ./usr/include/asm/zcrypt.h:169:2: error: unknown type name ‘uint32_t’ uint32_t target_id; ^~~~~~~~ ./usr/include/asm/zcrypt.h:170:2: error: unknown type name ‘uint32_t’ uint32_t ret_code; ^~~~~~~~ ./usr/include/asm/zcrypt.h:171:2: error: unknown type name ‘uint32_t’ uint32_t reserved1; ^~~~~~~~ ./usr/include/asm/zcrypt.h:172:2: error: unknown type name ‘uint32_t’ uint32_t reserved2; ^~~~~~~~ ./usr/include/asm/zcrypt.h:173:2: error: unknown type name ‘uint32_t’ uint32_t payload_len; ^~~~~~~~ ./usr/include/asm/zcrypt.h:182:2: error: unknown type name ‘uint16_t’ uint16_t ap_id; ^~~~~~~~ ./usr/include/asm/zcrypt.h:183:2: error: unknown type name ‘uint16_t’ uint16_t dom_id; ^~~~~~~~ ./usr/include/asm/zcrypt.h:198:2: error: unknown type name ‘uint16_t’ uint16_t targets_num; ^~~~~~~~ ./usr/include/asm/zcrypt.h:199:2: error: unknown type name ‘uint64_t’ uint64_t targets; ^~~~~~~~ ./usr/include/asm/zcrypt.h:200:2: error: unknown type name ‘uint64_t’ uint64_t weight; ^~~~~~~~ ./usr/include/asm/zcrypt.h:201:2: error: unknown type name ‘uint64_t’ uint64_t req_no; ^~~~~~~~ ./usr/include/asm/zcrypt.h:202:2: error: unknown type name ‘uint64_t’ uint64_t req_len; ^~~~~~~~ ./usr/include/asm/zcrypt.h:203:2: error: unknown type name ‘uint64_t’ uint64_t req; ^~~~~~~~ ./usr/include/asm/zcrypt.h:204:2: error: unknown type name ‘uint64_t’ uint64_t resp_len; ^~~~~~~~ ./usr/include/asm/zcrypt.h:205:2: error: unknown type name ‘uint64_t’ uint64_t resp; ^~~~~~~~ Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
