x86, ioapic: Format clean up for IOAPIC output
When IOAPIC data is displayed in "dmesg" with the help of the boot parameter "apic=debug" certain values are not formatted correctly wrt their size. In the "dmesg" snippet below, note that the output for "max redirection entries", and "IO APIC version" which are each defined to be just 8-bits long are displayed as 2 bytes in length. Similarly, "Dst" under the "IRQ redirection table" should only be 8-bits long. IO APIC #0...... ... ... .... register #01: 00170020 ....... : max redirection entries: 0017 ....... : PRQ implemented: 0 ....... : IO APIC version: 0020 ... ... .... IRQ redirection table: NR Dst Mask Trig IRR Pol Stat Dmod Deli Vect: 00 000 1 0 0 0 0 0 0 00 01 000 0 0 0 0 0 0 0 31 02 000 0 0 0 0 0 0 0 30 03 000 1 0 0 0 0 0 0 33 ... ... Do some formatting clean up, so you will see output like below: IO APIC #0...... ... ... .... register #01: 00170020 ....... : max redirection entries: 17 ....... : PRQ implemented: 0 ....... : IO APIC version: 20 ... ... ....
