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.

3508aae9b5 ARM: configs: Cleanup old Kconfig options
CONFIG_MMC_BLOCK_BOUNCE is gone since commit c3dccb74be ("mmc: core:
Delete bounce buffer Kconfig option").

CONFIG_LBDAF is gone since commit 72deb455b5 ("block: remove
CONFIG_LBDAF").

CONFIG_IOSCHED_DEADLINE and CONFIG_IOSCHED_CFQ are gone since
commit f382fb0bce ("block: remove legacy IO schedulers").

The IOSCHED_DEADLINE was replaced by MQ_IOSCHED_DEADLINE and it will be
now enabled by default (along with MQ_IOSCHED_KYBER).

The IOSCHED_BFQ seems to replace IOSCHED_CFQ so select it in configs
previously choosing the latter.

CONFIG_CROSS_COMPILE is gone since commit f1089c92da ("kbuild: remove
CONFIG_CROSS_COMPILE support").

6c48edcc95 ARM: 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").

752a47ef73 arm: am200epdkit_defconfig: convert to use libata PATA drivers
IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively.  However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers.  This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:

* testing efforts are divided between two subsystems

* having duplicate drivers for same hardware confuses users

This patch converts am200epdkit_defconfig to use libata PATA
drivers.

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

4da8b8208e ARM: Kill CONFIG_CPU_32
26-bit ARM support was removed a long time ago, and this symbol has
been defined to be 'y' ever since.  As it's never disabled anymore,
we can kill it without any side effects.
