Upstream commit f7c90c2aa4004808dff777ba6ae2c7294dd06851 ("x86/xen: don't write ptes directly in 32-bit PV guests") should be considered for stable kernels from 4.14 up (I'll send backports for older kernels when I know you are taking the patch). The patch avoids 32-bit Xen PV guests creating intermediate L1TF vulnerable PTEs. Juergen

Upstream commit b2d7a075a1ccef2fb321d595802190c8e9b39004 ("x86/pae: use 64 bit atomic xchg function in native_ptep_get_and_clear") should be considered for stable kernels from 4.17 up (I'll send backports for older kernels when I know you are taking the patch). The patch seems not only to avoid intermediate L1TF vulnerable PTEs, but there are reports of it fixing the issue mentioned in https://bugzilla.kernel.org/show_bug.cgi?id=198497 Juergen

[PATCH 7/7] perf tools: Fix maps__find_symbol_by_name()

by Arnaldo Carvalho de Melo

From: Adrian Hunter <adrian.hunter(a)intel.com> Commit 1c5aae7710bb ("perf machine: Create maps for x86 PTI entry trampolines") revealed a problem with maps__find_symbol_by_name() that resulted in probes not being found e.g. $ sudo perf probe xsk_mmap xsk_mmap is out of .text, skip it. Probe point 'xsk_mmap' not found. Error: Failed to add events. maps__find_symbol_by_name() can optionally return the map of the found symbol. It can get the map wrong because, in fact, the symbol is found on the map's dso, not allowing for the possibility that the dso has more than one map. Fix by always checking the map contains the symbol.

[PATCH stable] x86/tsc: Prevent result truncation on 32 bit

by Thomas Gleixner

Subject: x86/tsc: Prevent result truncation on 32 bit From: Chuanhua Lei <chuanhua.lei(a)linux.intel.com> Date: Thu Sep 6 18:03:23 2018 +0800 From: Chuanhua Lei <chuanhua.lei(a)linux.intel.com> Commit 17f6bac2249356c795339e03a0742cd79be3cab8 upstream. Loops per jiffy is calculated by multiplying tsc_khz with 1e3 and then dividing it by HZ. Both tsc_khz and the temporary variable holding the multiplication result are of type unsigned long, so on 32bit the result is truncated to the lower 32bit. Use u64 as type for the temporary variable and cast tsc_khz to it before multiplying. [ tglx: Backport to stable. Due to massive code changes is the upstream commit not applicable anymore. The issue has gone unnoticed in kernels pre 4.19 because the bogus LPJ value gets fixed up in a later stage of early boot, but it still might cause subtle and hard to debug issues between these two points. ] Fixes: dd759d93f4dd ("x86/timers: Add simple udelay calibration") Signed-off-by: Chuanhua Lei <chuanhua.lei(a)linux.intel.com> Signed-off-by: Thomas Gleixner <tglx(a)linutronix.de> Cc: yixin.zhu(a)linux.intel.com Cc: "H.

[STABLE v4.18 BACKPORT] drm/i915: set DP Main Stream Attribute for color range on DDI platforms

by Jani Nikula

commit 6209c285e7a5e68dbcdf8fd2456c6dd68433806b upstream. Since Haswell we have no color range indication either in the pipe or port registers for DP. 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.
