Subject: riscv: vDSO: Remove --hash-style=both
X-Git-Tag: v6.16-rc1~18^2~8
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2940954c1ac527386e5203d4be8263d704491fbe;p=thirdparty%2Fkernel%2Flinux.git

riscv: vDSO: Remove --hash-style=both

When RISC-V borned, DT_GNU_HASH had already became the de-facto
standard so DT_HASH is just wasting storage space.  Remove the explicit
--hash-style=both setting and rely on the distro toolchain default,
which is most likely "gnu" (i.e. generating only DT_GNU_HASH, no
DT_HASH).

Following the logic of commit 48f6430505c0
("arm64/vdso: Remove --hash-style=sysv").
