Subject: selftests/mm: remove arm64 nr_hugepages setup for va_high_addr_switch test
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7544d7969d84c1c4a078d1c5a7d4117fbf6f385c;p=thirdparty%2Fkernel%2Fstable.git

selftests/mm: remove arm64 nr_hugepages setup for va_high_addr_switch test

arm64 and x86_64 has the same nr_hugepages requriement for running the
va_high_addr_switch test.  Since commit d9d957bd7b61 ("selftests/mm: alloc
hugepages in va_high_addr_switch test"), the setup can be done in
va_high_addr_switch.sh.  So remove the duplicated setup.
