* kernel: Set CONFIG_RCU_CPU_STALL_TIMEOUT=21Hauke Mehrtens2021-09-091-1/+0
| | | | | | | | | | | | The default value for CONFIG_RCU_CPU_STALL_TIMEOUT was changed from 60 seconds to 21 seconds in 2012 in the upstream kernel. Some targets already use 21 seconds. This patch changes the default value in the generic configuration to 21 seconds and removes the target specific configuration options.

* kernel: move two symbols to the generic kconfigsRui Salvaterra2021-08-291-2/+0
| | | | | | | CONFIG_RCU_{NEED_SEGCBLIST,STALL_COMMON} are set basically everywhere. Move them to the generic kconfigs. And resort the generic kconfigs while at it. Signed-off-by: Rui Salvaterra <rsalvaterra@gmail.com>
* kernel: disable CONFIG_RCU_EXPERT and friendsRui Salvaterra2021-08-291-1/+0
| | | | | | | | | | | | | | Based on the existing documentation [1][2], I dare anyone to demonstrate that we need to fine-tune these RCU parameters. The (performance) breakage potential for doing so is immense, so let's just please put down this loaded footgun. Disable CONFIG_RCU_EXPERT and its dependent symbols. Additionally, remove the CONFIG_RCU_EXPERT symbol from the target kconfigs which contain it.

* kernel: Move CONFIG_USERIO to generic configHauke Mehrtens2021-03-271-1/+0
| | | | | | | | The CONFIG_USERIO option is unset in multiple target configurations. On the sunxi target it is activated. Move the kernel configuration option to the generic kernel configuration. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: Deactivate CONFIG_VFIO in generic kernel configHauke Mehrtens2021-03-271-1/+0
| | | | | | | | | Instead of deactivating this in every target config, deactivate it once in the generic kernel config. I was asked for this config option in a x86 64 build in OpenWrt 21.02.

* treewide: enable the vDSORui Salvaterra2020-10-131-1/+0
| | | | | | | The vDSO is used to accelerate some syscalls. It should work fine wherever it's available, so enable it globally for all targets. Signed-off-by: Rui Salvaterra <rsalvaterra@gmail.com>

* kernel: move F2FS_FS_XATTR and F2FS_STAT_FS symbols to genericDaniel Golle2020-10-091-1/+0
| | | | | | | | Similar to how it was already done for other filesystems' *_FS_XATTR kernel config symbols, also move CONFIG_F2FS_FS_XATTR=y and CONFIG_F2FS_STAT_FS=y to target/linux/generic. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
* kernel: clean up XATTR config symbolsPaul Spooren2020-10-091-1/+0
| | | | | | | | | | | | | Extended attributes are required for overlayfs and have hence been long ago enabled for jffs2, but should be enabled unconditionally for all other filesystems which may potentially serve as overlayfs' upper directory. Previously it was inconsistently added in multiple targets. Add symbols to generic kernel config and remove all *_XATTR symbols from target configs.
