Subject: arm64: kexec: Remove duplicate allocation for trans_pgd
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ee020bf6f14094c9ae434bb37e6957a1fdad513c;p=thirdparty%2Fkernel%2Flinux.git

arm64: kexec: Remove duplicate allocation for trans_pgd

trans_pgd would be allocated in trans_pgd_create_copy(), so remove the
duplicate allocation before calling trans_pgd_create_copy().
