disable= [IPV6]
See Documentation/networking/ipv6.txt.
+ disable_cpu_apicid= [X86,APIC,SMP]
+ Format: <int>
+ The number of initial APIC ID for the
+ corresponding CPU to be disabled at boot,
+ mostly used for the kdump 2nd kernel to
+ disable BSP to wake up multiple CPUs without
+ causing system reset or hang due to sending
+ INIT from AP to BSP.
+
disable_ddw [PPC/PSERIES]
Disable Dynamic DMA Window support. Use this if
to workaround buggy firmware.
edd= [EDD]
Format: {"off" | "on" | "skip[mbr]"}
+ efi= [EFI]
+ Format: { "old_map" }
+ old_map [X86-64]: switch to the old ioremap-based EFI
+ runtime services mapping. 32-bit still uses this one by
+ default.
+
efi_no_storage_paranoia [EFI; X86]
Using this parameter you can use more than 50% of
your efi variable storage. Use this parameter only if
noapic [SMP,APIC] Tells the kernel to not make use of any
IOAPICs that may be present in the system.
+ nokaslr [X86]
+ Disable kernel base offset ASLR (Address Space
+ Layout Randomization) if built into the kernel.
+
noautogroup Disable scheduler automatic task group creation.
nobats [PPC] Do not use BATs for mapping kernel lowmem
for RCU-preempt, and "s" for RCU-sched, and "N"
is the CPU number. This reduces OS jitter on the
offloaded CPUs, which can be useful for HPC and
-
real-time workloads. It can also improve energy
efficiency for asymmetric multiprocessors.

rcutree.blimit= [KNL]
- Set maximum number of finished RCU callbacks to process

+ Set maximum number of finished RCU callbacks to

rcutree.rcu_fanout_leaf= [KNL]
Increase the number of CPUs assigned to each

rcutree.qhimark= [KNL]
- Set threshold of queued

+ Set threshold of queued RCU callbacks beyond which

rcutree.qlowmark= [KNL]
Set threshold of queued RCU callbacks below which
