[PATCH v1 1/2] hyperv: Include linux/types.h to avoid build break

[PATCH v1 1/2] hyperv: Include linux/types.h to avoid build break

[Andy Shevchenko]

The commit 2ffd9e33ce4a

    ("x86/hyper-v: Use hypercall for remote TLB flush")

introduced a new C-file where uapi/linux/hyperv.h is included first.

This makes build failed since UAPI headers are heavily dependent to special
types of variables, e.g. __u8.

include/uapi/linux/hyperv.h:71:2: error: unknown type name ‘__u8’
  __u8 operation;
  ^~~~

Include linux/types.h to the UAPI header like many others do.

Oops, it's because I have an update to this file in my local uuid
branch.

In any case this is right thing to do independently of uuid.h inclusion.

Please, ignore this patch for now, but note the second one is still
valid.
