x86: small fixes to pcpu platform op handling
|
|
|
|
XENPF_get_cpuinfo should init the flags output field rather than only
|
|
modify it.
|
|
|
|
XENPF_cpu_online must check for the input CPU number to be in range.
|
|
|
|
XENPF_cpu_offline must also do that, and should also reject attempts to
|
|
offline CPU 0 (this fails in cpu_down() too, but preventing this here
|
|
appears more correct given that the code here calls
|
|
continue_hypercall_on_cpu(0, ...), which would be flawed if cpu_down()
|
|
would ever allow bringing down CPU 0 (and a distinct error code is
|
|
easier to deal with when debugging issues).
