Xiaoming Ni 88db0aa242 all arch: remove system call sys_sysctl
Since commit 61a47c1ad3 ("sysctl: Remove the sysctl system call"),
sys_sysctl is actually unavailable: any input can only return an error.

We have been warning about people using the sysctl system call for years
and believe there are no more users.  Even if there are users of this
interface if they have not complained or fixed their code by now they
probably are not going to, so there is no point in warning them any
longer.

So completely remove sys_sysctl on all architectures.

Krzysztof Kozlowski 7c04efc8d2 sh: configs: Remove useless UEVENT_HELPER_PATH
Remove the CONFIG_UEVENT_HELPER_PATH because:
1. It is disabled since commit 1be01d4a57 ("driver: base: Disable
   CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was
   made default to 'n',
2. It is not recommended (help message: "This should not be used today
   [...] creates a high system load") and was kept only for ancient
   userland,
3. Certain userland specifically requests it to be disabled (systemd
   README: "Legacy hotplug slows down the system and confuses udev").

Matt Fleming 248bc0d93b sh: Set CONFIG_SYSFS_DEPRECATED_V2=n
As the help for the config option suggests, this option really shouldn't
be set by default for any recent distribution as it changes the layout
of sysfs. I spotted this while running debian when udev got very
confused by the sysfs layout and failed to create some device nodes.

Magnus Damm cc6f33db30 sh: fix defconfigs for sh7751r boards
This patch fixes up the defconfig for various sh7751r based boards
by updating them to the single cpu subtype CONFIG_CPU_SUBTYPE_SH7751R.
The following sh4 boards are updated: hs7751rvoip, landisk, lboxre2,
systemh, titan.

The current defconfigs with two subtypes defined trigger a configuration
bug which result in kernel configurations with missing board support
code. We end up with kernels without board code and with generic machvec
only.

So we need this patch to make sure the board code gets compiled in.

Magnus Damm 56386f6424 sh: intc - add support for SH7750 and its variants
This patch converts the cpu specific 7750 setup code to use the
new intc controller. Many new vectors are added and multiple
processor variants including 7091, 7750, 7750s, 7750r, 7751 and
7751r should all have the correct vectors hooked up.

IRLM interrupts can be enabled using ipr_irq_enable_irlm() which
now is marked as __init.

This adds support for the L-BOX RE2 router.

	http://www.nttcom.co.jp/l-box/

L-BOX RE2 is a SH7751R-based router. It has CF, Cardbus, serial,
and LAN x2. This is one of the very few SH boards that a general
person can obtain now.

The L-BOX shipped with a 2.4.28 kernel, this is a rewritten patch
adding it to current git.
