Instead, there's a separate register for setting the DP Main Stream Attributes (MSA) directly. The MSA register definition makes no references to colorimetry, just a vague reference to the DP spec. The connection to the color range was lost. Apparently we've failed to set the proper MSA bit for limited, or CEA, range ever since the first DDI platforms. We've started setting other MSA parameters since commit dae847991a43 ("drm/i915: add intel_ddi_set_pipe_settings"). Without the crucial bit of information, the DP sink has no way of knowing the source is actually transmitting limited range RGB, leading to "washed out" colors. With the colorimetry information, compliant sinks should be able to handle the limited range properly. Native (i.e. non-LSPCON) HDMI was not affected because we do pass the color range via AVI infoframes. Though not the root cause, the problem was made worse for DDI platforms with commit 55bc60db5988 ("drm/i915: Add "Automatic" mode for the "Broadcast RGB" property"), which selects limited range RGB automatically based on the mode, as per the DP, HDMI and CEA specs. After all these years, the fix boils down to flipping one bit. [Per testing reports, this fixes DP sinks, but not the LSPCON. My educated guess is that the LSPCON fails to turn the CEA range MSA into AVI infoframes for HDMI.] Reported-by: Michał Kopeć <mkopec12(a)gmail.com> Reported-by: N.

This patch is the first one in the patch series: http://lkml.kernel.org/r/cover.thread-aa7b8d.your-ad-here.call-01533557518-… The patch series adds s390 support for utilizing newly available for s390 in gcc 9 flags -fentry -mrecord-mcount and -mnop-mcount, and adds generic -mnop-mcount support. And there is no benefit in backporting just the first one.

[PATCH v4 1/3] fs/dcache: Fix incorrect nr_dentry_unused accounting in shrink_dcache_sb()

by Waiman Long

The nr_dentry_unused per-cpu counter tracks dentries in both the LRU lists and the shrink lists where the DCACHE_LRU_LIST bit is set. The shrink_dcache_sb() function moves dentries from the LRU list to a shrink list and subtracts the dentry count from nr_dentry_unused. This is incorrect as the nr_dentry_unused count Will also be decremented in shrink_dentry_list() via d_shrink_del(). To fix this double decrement, the decrement in the shrink_dcache_sb() function is taken out. Fixes: 4e717f5c1083 ("list_lru: remove special case function list_lru_dispose_all."
