Subject[PATCH 0/9] strict user copy checks on x86_64
Date
It turns out that strict user copy checks (also known as
CONFIG_DEBUG_STRICT_USER_COPY_CHECKS) isn't actually implemented
on x86_64 and thus we aren't catching potential security holes
at compile time.

This series adds support for strict user copy checks on x86_64
and silences all the benign warnings in the x86_64 allyesconfig.

The final patch consolidates the config option as its duplicated
across mutliple arches. I don't know what tree this series should
go through so I tried to send the individual driver patches to the
respective maintainers.

Stephen Boyd (9):
iwlegacy: Silence DEBUG_STRICT_USER_COPY_CHECKS=y warning
iwlwifi: Silence DEBUG_STRICT_USER_COPY_CHECKS=y warning
[SCSI] lpfc: Silence DEBUG_STRICT_USER_COPY_CHECKS=y warning
debugfs: Silence DEBUG_STRICT_USER_COPY_CHECKS=y warning
kprobes: Silence DEBUG_STRICT_USER_COPY_CHECKS=y warning
Bluetooth: Silence DEBUG_STRICT_USER_COPY_CHECKS=y warning
ASoC: Silence DEBUG_STRICT_USER_COPY_CHECKS=y warning
x86: Implement strict user copy checks for x86_64
Consolidate CONFIG_DEBUG_STRICT_USER_COPY_CHECKS
