From mboxrd@z Thu Jan 1 00:00:00 1970 From: anders.roxell@linaro.org (Anders Roxell) Date: Tue, 30 Jan 2018 00:49:00 +0100 Subject: [PATCH] arch/arm/Kconfig: enable ARM_MODULE_PLTS when LOCKDEP=y Message-ID: <20180129234900.11121-1-anders.roxell@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org While testing multi_v7_defconfig with LOCKDEP enabled, the kernel fails to load simple modules, as reported by kselftest: [ 34.107620] test_printf: section 4 reloc 2 sym 'memset': relocation 28 out of range (0xbf046044 -> 0xc109f720) selftests: printf.sh [FAIL] The problem that is seen when LOCKDEP is enabled without ARM_MODULE_PLTS, is that LOCKDEP eats so much memory that the top of the kernel gets out of reach from the bottom of the module area.
