The kernel was updated to version 4.2.3.
3rd party additions (ndiswrapper) have been dropped.
The fixes for e1000e and mt7601u have been added as well, see
"kernel-patches-and-configs" project, branch v4.2.x.
It is no longer required to upload each archive
kernel-patches-and-configs.* to FileStore. They are now retrieved from
https://abf.io/soft/kernel-patches-and-configs/ according to the git
tags.
If you are going to build kernel version X.Y.Z release R, you need to
tag the appropriate commit in kernel-patches-and-configs git repo as
"X.Y.Z-R", without quotes.
For experiments and testing, one may still upload the archives with the
pacthes and configs to FileStore and probably edit the URL in SOURCE100
in the spec.
Most external components have been removed to simplify maintenance.
The following ones are kept because they are more important and/or
maintained well in upstream:
- BFQ
- AUFS
- ndiswrapper
- several bug fixes
reiser4 is kept too but disabled by default until its maintainers update
it for kernel 4.x.
1. Made ACPI stuff built-in:
'm' => 'y'
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
CONFIG_ACPI_BUTTON=y
CONFIG_ACPI_FAN=y
CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_THERMAL=y
not set => 'y'
CONFIG_ACPI_HOTPLUG_MEMORY=y (x64 only)
2. Enabled support for security attributes (used by SElinux, etc.) in 2
more file systems:
CONFIG_9P_FS_SECURITY=y
CONFIG_F2FS_FS_SECURITY=y (Fedora 21 does not build F2FS, by the way.)
3. Make the core DM-related components built-in, enable RAID
detection at boot:
CONFIG_BLK_DEV_DM=y
CONFIG_MD_AUTODETECT=y
4. Unset CONFIG_EMBEDDED. These kernels are not for embedded systems
anyway.
5. Make evdev input driver built-in:
CONFIG_INPUT_EVDEV=y
6. Increase the memory buffer to store the kernel log from 128Kb to
256Kb. This will allow for more messages to be stored there, good for
bug reporting.
CONFIG_LOG_BUF_SHIFT=18
7. No need to print the kernel logs to a printer directly:
Unset CONFIG_LP_CONSOLE.
8. Disable "opportunistic suspend" for now, it is still an experimental
feature.
Unset CONFIG_PM_AUTOSLEEP.
Apart from the update to version 3.14.31 itself, the following changes
were made:
* BFQ was updated to version 7r7.
* arch-x86-kernel-tsc-hide-warning.patch was removed as the issue had
been addressed in the mainline.
* A patch was added to increase inotify max_user_watch limit to 32768
(bug 4791).
* A patch was added that might help fix bug 4613 (no output to an
external monitor on HP EliteBook 820 G1).
