Subject: Add parametrized version of s390_inferior_tid
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4dab71822783834788e26c8858a37e3189efbdba;p=thirdparty%2Fbinutils-gdb.git

Add parametrized version of s390_inferior_tid

In the next patches, we'll want to use this function with a ptid other
than inferior_ptid, so I add it with a separate patch to keep things
clean.

gdb/ChangeLog:

	* s390-linux-nat.c (s390_inferior_tid): Add overload with ptid
	parameter.
