+Subject: [PATCH] linux-user: remove host stime() syscall
+
+stime() has been withdrawn from glibc
+(12cbde1dae6f "Use clock_settime to implement stime; withdraw stime.")
+
+Implement the target stime() syscall using host
+clock_settime(CLOCK_REALTIME, ...) as it is done internally in glibc.
+
+Tested qemu-ppc/x86_64 with:
+
+ #include <time.h>
+ #include <stdio.h>
+
+ int main(void)
+ {
+ time_t t;
+ int ret;
+
+ /* date -u -d"2019-11-12T15:11:00" "+%s" */
+ t = 1573571460;
+ ret = stime(&t);
+ printf("ret %d\n", ret);
+ return 0;
+ }
+
+ # date; ./stime; date
+ Tue Nov 12 14:18:32 UTC 2019
+ ret 0
+ Tue Nov 12 15:11:00 UTC 2019
+
+Upstream-Status: Backport [https://git.qemu.org/?p=qemu.git;a=commit;h=0f1f2d4596aee037d3ccbcf10592466daa54107f]
