#1228699 — [PATCH 4.1 002/102] x86/ldt: Correct LDT access in single stepping logic

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Juergen Gross <jgross@suse.com>

commit 136d9d83c07c5e30ac49fc83b27e8c4842f108fc upstream.

Commit 37868fe113ff ("x86/ldt: Make modify_ldt synchronous")
introduced a new struct ldt_struct anchored at mm->context.ldt.

convert_ip_to_linear() was changed to reflect this, but indexing
into the ldt has to be changed as the pointer is no longer void *.

#1228700 — [PATCH 4.1 003/102] x86/ldt: Correct FPU emulation access to LDT

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Juergen Gross <jgross@suse.com>

commit 4809146b86c3d41ce588fdb767d021e2a80600dd upstream.

Commit 37868fe113ff ("x86/ldt: Make modify_ldt synchronous")
introduced a new struct ldt_struct anchored at mm->context.ldt.

Adapt the x86 fpu emulation code to use that new structure.

#1228712 — [PATCH 4.1 017/102] s390/setup: fix novx parameter

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

commit 89b1145e93771d727645c96e323539c029b63f1c upstream.

The novx parameter disables the vector facility but the HWCAP_S390_VXRS
bit in the ELf hardware capabilies is always set if the machine has
the vector facility. If the user space program uses the "vx" string
in the features field of /proc/cpuinfo to utilize vector instruction
it will crash if the novx kernel paramter is set.

Convert setup_hwcaps to an arch_initcall and use MACHINE_HAS_VX to
decide if the HWCAPS_S390_VXRS bit needs to be set.

#1228731 — [PATCH 4.1 012/102] drm/qxl: validate monitors config modes

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jonathon Jongsma <jjongsma@redhat.com>

commit bd3e1c7c6de9f5f70d97cdb6c817151c0477c5e3 upstream.

Due to some recent changes in
drm_helper_probe_single_connector_modes_merge_bits(), old custom modes
were not being pruned properly. In current kernels,
drm_mode_validate_basic() is called to sanity-check each mode in the
list. If the sanity-check passes, the mode's status gets set to to
MODE_OK. In older kernels this check was not done, so old custom modes
would still have a status of MODE_UNVERIFIED at this point, and would
therefore be pruned later in the function.

As a result of this new behavior, the list of modes for a device always
includes every custom mode ever configured for the device, with the
largest one listed first. Since desktop environments usually choose the
first preferred mode when a hotplug event is emitted, this had the
result of making it very difficult for the user to reduce the size of
the display.

The qxl driver did implement the mode_valid connector function, but it
was empty. In order to restore the old behavior where old custom modes
are pruned, we implement a proper mode_valid function for the qxl
driver. This function now checks each mode against the last configured
custom mode and the list of standard modes. If the mode doesn't match
any of these, its status is set to MODE_BAD so that it will be pruned as
expected.

It looks like this patch needs to be backported as well :

commit cb8cc37f4d38d96552f2c52deb15e511cdacf906
Author: Caesar Wang <wxt@rock-chips.com>
Date:   Mon Jul 6 11:37:23 2015 +0800

    ARM: rockchip: fix broken build
    
    The following was seen in branch[0] build.
    
    arch/arm/mach-rockchip/platsmp.c:154:23: error:
        'rockchip_secondary_startup' undeclared (first use in this function)
    
    branch[0]:
    git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip.git
    v4.3-armsoc/soc
    
    The broken build is caused by the commit fe4407c0dc58
    ("ARM: rockchip: fix the CPU soft reset").
    
    Signed-off-by: Caesar Wang <wxt@rock-chips.com>
    
    The breakage was a result of it being wrongly merged in my branch with
    the cache invalidation rework from Russell 02b4e2756e01c
    ("ARM: v7 setup function should invalidate L1 cache").

Yes, just build tested only with arm. With this patch both 4.1.8-rc1 and
4.2.1-rc1 build successfull for arm allmodconfig.
