[PATCH 5.4 v2 2/6] arch: fix broken BuildID for arm64 and riscv

From: Masahiro Yamada commit 99cb0d917ffa1ab628bb67364ca9b162c07699b1 upstream. Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux since commit 994b7ac1697b ("arm64: remove special treatment for the link order of head.o"). The issue is that the type of .notes section, which

[PATCH 5.4 v2 3/6] powerpc/vmlinux.lds: Define RUNTIME_DISCARD_EXIT

From: Michael Ellerman commit 4b9880dbf3bdba3a7c56445137c3d0e30aaa0a40 upstream. The powerpc linker script explicitly includes .exit.text, because otherwise the link fails due to references from __bug_table and __ex_table. The code is freed (discarded) at runtime along with .init.text and data.

[PATCH 5.4 v2 4/6] powerpc/vmlinux.lds: Don't discard .rela* for relocatable builds

From: Michael Ellerman commit 07b050f9290ee012a407a0f64151db902a1520f5 upstream. Relocatable kernels must not discard relocations, they need to be processed at runtime. As such they are included for CONFIG_RELOCATABLE builds in the powerpc linker script (line 340). However they are also uncondi

[PATCH 5.4 v2 6/6] sh: define RUNTIME_DISCARD_EXIT

commit c1c551bebf928889e7a8fef7415b44f9a64975f4 upstream. sh vmlinux fails to link with GNU ld < 2.40 (likely < 2.36) since commit 99cb0d917ffa ("arch: fix broken BuildID for arm64 and riscv"). This is similar to fixes for powerpc and s390: commit 4b9880dbf3bd ("powerpc/vmlinux.lds: Define RUNTIM

[PATCH 5.4 v2 5/6] s390: define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36

From: Masahiro Yamada commit a494398bde273143c2352dd373cad8211f7d94b2 upstream. Nathan Chancellor reports that the s390 vmlinux fails to link with GNU ld < 2.36 since commit 99cb0d917ffa ("arch: fix broken BuildID for arm64 and riscv"). It happens for defconfig, or more specifically for CONFIG_

[PATCH 6.1 v2 2/7] arm64: remove special treatment for the link order of head.o

From: Masahiro Yamada commit 994b7ac1697b4581b7726d2ac64321e3c840229b upstream. In the previous discussion (see the Link tag), Ard pointed out that arm/arm64/kernel/head.o does not need any special treatment - the only piece that must appear right at the start of the binary image is the image he
