We're seeing the following problems, as with 6.1, with GCC-8 on allmodconfig on the following architectures: Arm64 [2], Arm [1][2], i386 [1], mips [1], parisc [1], sh [1]. With GCC-12 on allmodconfig: arm64 [2], arm [2].

[1] Problem on 32-bits:
| /builds/linux/drivers/pwm/pwm-tegra.c: In function 'tegra_pwm_config':
| /builds/linux/drivers/pwm/pwm-tegra.c:148:53: error: result of '1000000000 << 8' requires 39 bits to represent, but 'long int' only has 32 bits [-Werror=shift-overflow=]
|    required_clk_rate = DIV_ROUND_UP_ULL(NSEC_PER_SEC << PWM_DUTY_WIDTH,
|                                                      ^~
| /builds/linux/include/linux/math.h:40:32: note: in definition of macro 'DIV_ROUND_DOWN_ULL'
|   ({ unsigned long long _tmp = (ll); do_div(_tmp, d); _tmp; })
|                                 ^~
| /builds/linux/drivers/pwm/pwm-tegra.c:148:23: note: in expansion of macro 'DIV_ROUND_UP_ULL'
|    required_clk_rate = DIV_ROUND_UP_ULL(NSEC_PER_SEC << PWM_DUTY_WIDTH,
|                        ^~~~~~~~~~~~~~~~
| cc1: all warnings being treated as errors

And [2] problem with qcom_rpm:

| /builds/linux/drivers/mfd/qcom_rpm.c: In function 'qcom_rpm_remove':
| /builds/linux/drivers/mfd/qcom_rpm.c:680:19: error: unused variable 'rpm' [-Werror=unused-variable]
|   struct qcom_rpm *rpm = dev_get_drvdata(&pdev->dev);
|                    ^~~
