Subject: [PATCH AUTOSEL 5.15 41/41] perf/imx_ddr: Fix undefined behavior due to shift overflowing the constant
Date: Mon, 11 Apr 2022 20:46:53 -0400 [thread overview]
Message-ID: <20220412004656.350101-41-sashal@kernel.org> (raw)
In-Reply-To: <20220412004656.350101-1-sashal@kernel.org>
From: Borislav Petkov <bp@suse.de>
[ Upstream commit d02b4dd84e1a90f7f1444d027c0289bf355b0d5a ]
Fix:
In file included from <command-line>:0:0:
In function ‘ddr_perf_counter_enable’,
inlined from ‘ddr_perf_irq_handler’ at drivers/perf/fsl_imx8_ddr_perf.c:651:2:
././include/linux/compiler_types.h:352:38: error: call to ‘__compiletime_assert_729’ \
declared with attribute error: FIELD_PREP: mask is not constant
_compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)
...
See https://lore.kernel.org/r/YkwQ6%2BtIH8GQpuct@zn.tnic for the gory
details as to why it triggers with older gccs only.
