I'm afraid this patch contains a licence violation, contrary to your
S-O-B.


You have moved this:

> --- a/tools/firmware/hvmloader/acpi/build.c
> +++ b/tools/firmware/hvmloader/acpi/build.c
...
> -struct acpi_info {
> -    uint8_t  com1_present:1;    /* 0[0] - System has COM1? */
> -    uint8_t  com2_present:1;    /* 0[1] - System has COM2? */
> -    uint8_t  lpt1_present:1;    /* 0[2] - System has LPT1? */


Into a new file:

The original file has this copyright header:

(rewrapped for legibility).  The dates haven't been updated for ages,
but this file is clearly GPLv2-only.


However your new file has this copyright header (again, wrapped);

There are two serious problems with this.

1. You have dropped the copyright attribution to Intel and Xensource.

2. You have changed the licence to BSD-style, even though the original
   was GPLv2-only.


Please be more careful!

Thanks,
Ian.
