Subject: parisc: PDT/firmware: Add support to read PDT on older PAT-machines
Older machines with a PAT firmware (e.g. the rp5470) return their Page
Deallocation Table (PDT) info per cell via the PDC_PAT_MEM_PD_INFO PDC call.
This patch adds the necessary structures and wrappers to call firmware.

Subject: parisc: PDT: Add full support for memory failure via Page
Deallocation Table (PDT)
This patch adds full support to read PDT info on all machine types. At bootup
the PDT is read and bad memory excluded from usage via memblock_reserve().
Later in the boot process a kernel thread is started (kpdtd) which regularily
checks firmare for new reported bad memory and tries to soft offline pages in
case of correctable errors and to kill processes and exclude such memory in
case of uncorrectable errors via memory_failure().

BUG: spinlock bad magic on CPU#0, swapper/0
in unwind code. Let's avoid that by static initialization.

Subject: parisc: Drop MADV_SPACEAVAIL, MADV_VPS_PURGE and MADV_VPS_INHERIT
Those aren't used or implemented anywhere in Linux.
Furthermore, MADV_SPACEAVAIL seems to be a HP-UX related flag which is
implemented as null operation in HP-UX. And since we don't support running
HP-UX binaries there is no need to keep it.

Subject: parisc: Fix up devices below a PCI-PCI MegaRAID controller bridge
A MegaRAID PCI card in my rp5470 acts as PCI-PCI bridge.
Resource allocation for PCI devices behind such a bridge is quite incomplete,
so that syslog reports those warnings:
