+Subject: arm64: module: remove (NOLOAD) from linker script
+
+From: Fangrui Song <maskray@google.com>
+
+commit 4013e26670c590944abdab56c4fa797527b74325 upstream.
+
+On ELF, (NOLOAD) sets the section type to SHT_NOBITS[1]. It is conceptually
+inappropriate for .plt and .text.* sections which are always
+SHT_PROGBITS.
+
+In GNU ld, if PLT entries are needed, .plt will be SHT_PROGBITS anyway
+and (NOLOAD) will be essentially ignored. In ld.lld, since
+https://reviews.llvm.org/D118840 ("[ELF] Support (TYPE=<value>) to
+customize the output section type"), ld.lld will report a `section type
+mismatch` error. Just remove (NOLOAD) to fix the error.
+
+[1] https://lld.llvm.org/ELF/linker_script.html As of today, "The
+section should be marked as not loadable" on
+https://sourceware.org/binutils/docs/ld/Output-Section-Type.html is
+outdated for ELF.
