+Subject: perf inject: Fix GEN_ELF_TEXT_OFFSET for jit
+
+From: Adrian Hunter <adrian.hunter@intel.com>
+
+[ Upstream commit 89b15d00527b7825ff19130ed83478e80e3fae99 ]
+
+When a program header was added, it moved the text section but
+GEN_ELF_TEXT_OFFSET was not updated.
+
+Fix by adding the program header size and aligning.

+Fixes: babd04386b1df8c3 ("perf jit: Include program header in ELF files")
