Performance oriented customized Linux kernel based on the mainline kernel.

When kernel booting, it will create a cpuid map between the logical cpus and physical cpus. In a normal boot, the cpuid map is as below: Physical Logical 0 ==> 0 1 ==> 1 But in kdump, there is a condition that the crash happens at the physical cpu1, and the crash kernel will run at the physical cpu1 too, so the cpuid map in crash kernel is as below: Physical Logical 1 ==> 0 0 ==> 1 The functions zynq_slcr_cpu_stop/start is to stop/start the physical cpus, the parameter cpu should be the physical cpuid. So use cpu_logical_map to translate the logical cpuid to physical cpuid. Or else the logical cpu0(physical cpu1) will stop itself and the processor will hang.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
