parisc: Fix pdc_toc_pim_11 and pdc_toc_pim_20 definitions The definitions for pdc_toc_pim_11 and pdc_toc_pim_20 are wrong since they include an entry for a hversion field which doesn't exist in the specification. Fix this and clean up some whitespaces so that the whole file will be in sync with it's copy in the SeaBIOS-hppa sources.

parisc: add support for TOC (transfer of control) Almost all PA-RISC machines have either a button that is labeled with 'TOC' or a BMC function to trigger a TOC. TOC is a non-maskable interrupt that is sent to the processor. This can be used for diagnostic purposes like obtaining a stack trace/register dump or to enter KDB/KGDB. As an example, on my c8000, TOC can be used with: CONFIG_KGDB=y CONFIG_KGDB_KDB=y and the 'kgdboc=ttyS0,115200' appended to the command line. Press ^[( on serial console, which will enter the BMC command line, and enter 'TOC s': root@(none):/# ( cli>TOC s Sending TOC/INIT. <Cpu3> 2800035d03e00000 0000000040c21ac8 CC_ERR_CHECK_TOC <Cpu0> 2800035d00e00000 0000000040c21ad0 CC_ERR_CHECK_TOC <Cpu2> 2800035d02e00000 0000000040c21ac8 CC_ERR_CHECK_TOC <Cpu1> 2800035d01e00000 0000000040c21ad0 CC_ERR_CHECK_TOC <Cpu3> 37000f7303e00000 2000000000000000 CC_ERR_CPU_CHECK_SUMMARY <Cpu0> 37000f7300e00000 2000000000000000 CC_ERR_CPU_CHECK_SUMMARY <Cpu2> 37000f7302e00000 2000000000000000 CC_ERR_CPU_CHECK_SUMMARY <Cpu1> 37000f7301e00000 2000000000000000 CC_ERR_CPU_CHECK_SUMMARY <Cpu3> 4300100803e00000 c0000000001d26cc CC_MC_BR_TO_OS_TOC <Cpu0> 4300100800e00000 c0000000001d26cc CC_MC_BR_TO_OS_TOC <Cpu2> 4300100802e00000 c0000000001d26cc CC_MC_BR_TO_OS_TOC <Cpu1> 4300100801e00000 c0000000001d26cc CC_MC_BR_TO_OS_TOC Entering kdb (current=0x00000000411cef80, pid 0) on processor 0 due to NonMaskable Interrupt @ 0x40c21ad0 [0]kdb> Signed-off-by: Sven Schnelle <svens@stackframe.org> Signed-off-by: Helge Deller <deller@gmx.de>

parisc: Add constants for PDC_RELOCATE PDC call The PDC_RELOCATE function is called by HP-UX shortly before crashing. So, we need to handle it in qemu and thus it makes sense to add the constant here. Additionally add other subfunctions like PDC_MODEL_GET_PLATFORM_INFO (to get product and serial numbers) and PDC_TOD_CALIBRATE (to calibrate timers) too. Signed-off-by: Helge Deller <deller@gmx.de>

License cleanup: add SPDX license identifier to uapi header files with no license Many user space API headers are missing licensing information, which makes it hard for compliance tools to determine the correct license. By default are files without license information under the default license of the kernel, which is GPLV2. Marking them GPLV2 would exclude them from being included in non GPLV2 code, which is obviously not intended. The user space API headers fall under the syscall exception which is in the kernels COPYING file: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". otherwise syscall usage would not be possible. Update the files which contain no license information with an SPDX license identifier. The chosen identifier is 'GPL-2.0 WITH Linux-syscall-note' which is the officially assigned identifier for the Linux syscall exception. SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

parisc: Add Page Deallocation Table (PDT) support The firmare in most parisc machines maintains a Page Deallocation Table (PDT) which holds a list of physical memory addresses where hardware detected memory errors (single bit and double bit errors). This patch adds the missing PDC firmware calls and the logic to read the PDT from firmware, report all current PDT entries and exclude the reported bad memory from being used by Linux.
