scripts/mksysmap: Fix escape chars '$'
[ Upstream commit 7a6c355b55c051eb37cb15d191241da3aa3d6cba ]
Commit b18b047002b7 ("kbuild: change scripts/mksysmap into sed script")
changed the invocation of the script, to call sed directly without
shell.
That means, the current extra escape that was added in:
commit ec336aa83162 ("scripts/mksysmap: Fix badly escaped '$'")
for the shell is not correct any more, at the moment the stack traces
for nvhe are corrupted:
[ 22.840904] kvm [190]: [<ffff80008116dd54>] __kvm_nvhe_$x.220+0x58/0x9c
[ 22.842913] kvm [190]: [<ffff8000811709bc>] __kvm_nvhe_$x.9+0x44/0x50
[ 22.844112] kvm [190]: [<ffff80008116f8fc>] __kvm_nvhe___skip_pauth_save+0x4/0x4
With this patch:
[ 25.793513] kvm [192]: nVHE call trace:
[ 25.794141] kvm [192]: [<ffff80008116dd54>] __kvm_nvhe_hyp_panic+0xb0/0xf4
[ 25.796590] kvm [192]: [<ffff8000811709bc>] __kvm_nvhe_handle_trap+0xe4/0x188
[ 25.797553] kvm [192]: [<ffff80008116f8fc>] __kvm_nvhe___skip_pauth_save+0x4/0x4
