1889 This is a kernel model which is known a VSMP but lately has been
1890 marketesed into SMVP.
1891 Virtual SMP uses the processor's VPEs to implement virtual
1892 processors. In currently available configuration of the 34K processor
1893 this allows for a dual processor. Both processors will share the same
1894 primary caches; each will obtain the half of the TLB for it's own
1895 exclusive use. For a layman this model can be described as similar to
1896 what Intel calls Hyperthreading.

1915 is presenting the available TC's of the core as processors to Linux.
1916 On currently available 34K processors this means a Linux system will
1917 see up to 5 processors. The implementation of the SMTC kernel differs
1918 significantly from VSMP and cannot efficiently coexist in the same
1919 kernel binary so the choice between VSMP and SMTC is a compile time

2312 It is an ongoing process to be certain the hardware in a machine
2313 is properly shutdown, so do not be surprised if this code does not
2314 initially work for you. It may help to enable device hotplugging
2315 support. As of this writing the exact hardware interface is
2316 strongly in flux, so no good recommendation can be made.

2318config CRASH_DUMP
2319 bool "Kernel crash dumps"
2320 help
2321 Generate crash dump after being started by kexec.
2322 This should be normally only set in special crash dump kernels
2323 which are loaded in the main kernel with kexec-tools into
2324 a specially reserved region and then later executed after
2325 a crash by kdump/kexec. The crash dump kernel must be compiled
2326 to a memory address not used by the main kernel or firmware using
2327 PHYSICAL_START.
2328
2329config PHYSICAL_START
2330 hex "Physical address where the kernel is loaded"
2331 default "0xffffffff84000000" if 64BIT
2332 default "0x84000000" if 32BIT
2333 depends on CRASH_DUMP
2334 help
2335 This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
2336 If you plan to use kernel for capturing the crash dump change
2337 this value to start of the reserved region (the "X" value as
2338 specified in the "crashkernel=YM@XM" command line boot parameter
2339 passed to the panic-ed kernel).

2345 help
2346 This kernel feature is useful for number crunching applications
2347 that may need to compute untrusted bytecode during their
2348 execution. By using pipes or other transports made available to
2349 the process as file descriptors supporting the read/write
2350 syscalls, it's possible to isolate those applications in
2351 their own address space using seccomp. Once seccomp is
2352 enabled via /proc/<pid>/seccomp, it cannot be disabled
2353 and the task is only allowed to execute a few safe syscalls
2354 defined by each seccomp mode.
2355
2356 If unsure, say Y. Only embedded should say N here.

2418 The Extended Industry Standard Architecture (EISA) bus was
2419 developed as an open alternative to the IBM MicroChannel bus.
2420
2421 The EISA bus provided some of the features of the IBM MicroChannel
2422 bus while maintaining backward compatibility with cards made for
2423 the older ISA bus. The EISA bus saw limited use between 1988 and
2424 1995 when it was made obsolete by the PCI bus.
