Subject: [PATCH] drm/mgag200: Fix PLL setup for G200_SE_A rev >=4
|
||||
|
||||
commit b389286d0234e1edbaf62ed8bc0892a568c33662 upstream.
|
||||
|
||||
For G200_SE_A, PLL M setting is wrong, which leads to blank screen,
|
||||
or "signal out of range" on VGA display.
|
||||
previous code had "m |= 0x80" which was changed to
|
||||
m |= ((pixpllcn & BIT(8)) >> 1);
|
||||
|
||||
Tested on G200_SE_A rev 42
|
||||
|
||||
This line of code was moved to another file with
|
||||
commit 877507bb954e ("drm/mgag200: Provide per-device callbacks for
|
||||
PIXPLLC") but can be easily backported before this commit.
|
||||
|
||||
v2: * put BIT(7) First to respect MSB-to-LSB (Thomas)
|
||||
* Add a comment to explain that this bit must be set (Thomas)

||||

Subject: [PATCH] mm, mremap: fix mremap() expanding vma with addr inside vma
|

MIME-Version: 1.0

commit 6f12be792fde994ed934168f93c2a0d2a0cf0bc5 upstream.
|
||||
|
||||
Since 6.1 we have noticed random rpm install failures that were tracked to
|
||||
mremap() returning -ENOMEM and to commit ca3d76b0aa80 ("mm: add merging
|
||||
after mremap resize").
|
||||
|
||||
The problem occurs when mremap() expands a VMA in place, but using an
|
||||
starting address that's not vma->vm_start, but somewhere in the middle.
|
||||
The extension_pgoff calculation introduced by the commit is wrong in that
|
||||
case, so vma_merge() fails due to pgoffs not being compatible. Fix the
|
||||
calculation.
|
||||
|
||||
By the way it seems that the situations, where rpm now expands a vma from
|
||||
the middle, were made possible also due to that commit, thanks to the
|
||||
improved vma merging. Yet it should work just fine, except for the buggy
|
||||
calculation.

Subject: [PATCH] mm/mempolicy: fix memory leak in set_mempolicy_home_node

system call
|

|

commit 38ce7c9bdfc228c14d7621ba36d3eebedd9d4f76 upstream.
|
||||
|
||||
When encountering any vma in the range with policy other than MPOL_BIND or
|
||||
MPOL_PREFERRED_MANY, an error is returned without issuing a mpol_put on
|
||||
the policy just allocated with mpol_dup().
|
||||
|

This allows arbitrary users to leak kernel memory.

Subject: [PATCH] ACPI: x86: s2idle: Force AMD GUID/_REV 2 on HP Elitebook 865
|
||||
|
||||
commit 3ea45390e9c0d35805ef8357ace55594fd4233d0 upstream.
|
||||
|
||||
HP Elitebook 865 supports both the AMD GUID w/ _REV 2 and Microsoft
|
||||
GUID with _REV 0. Both have very similar code but the AMD GUID
|
||||
has a special workaround that is specific to a problem with
|
||||
spurious wakeups on systems with Qualcomm WLAN.
|
||||
|
||||
This is believed to be a bug in the Qualcomm WLAN F/W (it doesn't
|
||||
affect any other WLAN H/W). If this WLAN firmware is fixed this
|
||||
quirk can be dropped.

Subject: [PATCH] ACPI: x86: s2idle: Stop using AMD specific codepath for
|
||||
Rembrandt+
|
||||
|
||||
commit e555c85792bd5f9828a2fd2ca9761f70efb1c77b upstream.
|
||||
|
||||
After we introduced a module parameter and quirk infrastructure for
|
||||
picking the Microsoft GUID over the SOC vendor GUID we discovered
|
||||
that lots and lots of systems are getting this wrong.
|
||||
|
||||
The table continues to grow, and is becoming unwieldy.
|
||||
|
||||
We don't really have any benefit to forcing vendors to populate the
|
||||
AMD GUID. This is just extra work, and more and more vendors seem
|
||||
to mess it up. As the Microsoft GUID is used by Windows as well,
|
||||
it's very likely that it won't be messed up like this.
|
||||
|
||||
So drop all the quirks forcing it and the Rembrandt behavior. This
|
||||
means that Cezanne or later effectively only run the Microsoft GUID
|
||||
codepath with the exception of HP Elitebook 8*5 G9.
