Known bugs

These are bugs we have introduced, but did not affected our project so far

• lg_cpu.regs became a pointer (as in x86_32 version)
  • We have made an allocation without dealocating memory
  • In arch/x86_64/kernel/asm_offsets_64.c we need to reconsider a few symbols like LG_CPU_regs or LG_CPU_regs_rax
• lg->cpus[] is no longer an array of pointers.
  • We don't allocate memory any more, but we have to eliminate the part where the memory was released because we'll get a free error
• Regs variable is moved to lg_cpu
  • When RedHat wrote the switcher, regs variable was declared in lg_cpu_data structure. Afterwards it was moved to lg_cpu. This means we need to take care in switcher ASM code of a few variables:
