up_threshold: defines what the average CPU usage between the samplings
of 'sampling_rate' needs to be for the kernel to make a decision on
whether it should increase the frequency. For example when it is set
-to its default value of '80' it means that between the checking
-intervals the CPU needs to be on average more than 80% in use to then
+to its default value of '95' it means that between the checking
+intervals the CPU needs to be on average more than 95% in use to then
decide that the CPU frequency needs to be increased.
ignore_nice_load: this parameter takes a value of '0' or '1'. When
individual lists does not affect propagation or the way propagation
tree is modified by operations.
+ All vfsmounts in a peer group have the same ->mnt_master. If it is
+ non-NULL, they form a contiguous (ordered) segment of slave list.
+
A example propagation tree looks as shown in the figure below.
[ NOTE: Though it looks like a forest, if we consider all the shared
mounts as a conceptual entity called 'pnode', it becomes a tree]
NOTE: The propagation tree is orthogonal to the mount tree.
+8B Locking:
+
+ ->mnt_share, ->mnt_slave, ->mnt_slave_list, ->mnt_master are protected
+ by namespace_sem (exclusive for modifications, shared for reading).
+
+ Normally we have ->mnt_flags modifications serialized by vfsmount_lock.
+ There are two exceptions: do_add_mount() and clone_mnt().
+ The former modifies a vfsmount that has not been visible in any shared
+ data structures yet.
+ The latter holds namespace_sem and the only references to vfsmount
+ are in lists that can't be traversed without namespace_sem.
-8B Algorithm:
+8C Algorithm:
The crux of the implementation resides in rbind/move operation.
acpi_display_output=video
See above.
+ acpi_early_pdc_eval [HW,ACPI] Evaluate processor _PDC methods
+ early. Needed on some platforms to properly
+ initialize the EC.
+
acpi_irq_balance [HW,ACPI]
ACPI will balance active IRQs
default in APIC mode
aic79xx= [HW,SCSI]
See Documentation/scsi/aic79xx.txt.
+ alignment= [KNL,ARM]
+ Allow the default userspace alignment fault handler
+ behaviour to be specified. Bit 0 enables warnings,
+ bit 1 enables fixups, and bit 2 sends a segfault.
+
amd_iommu= [HW,X86-84]
Pass parameters to the AMD IOMMU driver in the system.
Possible values are:
Default: 5
max_addresses - INTEGER
- Number of maximum addresses per interface. 0 disables limitation.
- It is recommended not set too large value (or 0) because it would
- be too easy way to crash kernel to allow to create too much of
- autoconfigured addresses.
+ Maximum number of autoconfigured addresses per interface. Setting
+ to zero disables the limitation. It is not recommended to set this
+ value too large (or to zero) because it would be an easy way to
+ crash the kernel by allowing too many addresses to be created.
Default: 16
disable_ipv6 - BOOLEAN

- Choose this option if you want kernel modesetting enabled by default,

- userspaces with this enabled will cause pain.
+ Choose this option if you want kernel modesetting enabled by default.
+
+ This is a completely new driver. It's only part of the existing drm
+ for compatibility reasons. It requires an entirely different graphics
+ stack above it and works very differently from the old drm stack.
+ i.e. don't enable this unless you know what you are doing it may
+ cause issues or bugs compared to the previous userspace driver stack.
When kernel modesetting is enabled the IOCTL of radeon/drm
driver are considered as invalid and an error message is printed
