* s390: fix kernel crash due to linkage stack instructionsMartin Schwidefsky2014-02-051-2/+5
| | | | | | | | | | | | | | | The kernel currently crashes with a low-address-protection exception if a user space process executes an instruction that tries to use the linkage stack. Set the base-ASTE origin and the subspace-ASTE origin of the dispatchable-unit-control-table to point to a dummy ASTE. Set up control register 15 to point to an empty linkage stack with no room left. A user space process with a linkage stack instruction will still crash but with a different exception which is correctly translated to a segmentation fault instead of a kernel oops.

* s390/mm: let kernel text section always begin at 1MBHeiko Carstens2012-10-091-3/+0
| | | | | | | | | | | Let the kernel text section always begin at 1MB. This allows to always have a large frame in the identity mapping of the kernel image for beginning of the text section, if the machine has EDAT1 support. Moving the beginning from 64K to 1MB doesn't cost any memory, since we make the memory between 64K and 1MB available for the page allocator.

* s390/comments: unify copyright messages and remove file namesHeiko Carstens2012-07-201-3/+1
| | | | | | | | | | | | | | Remove the file name from the comment at top of many files. In most cases the file name was wrong anyway, so it's rather pointless. Also unify the IBM copyright statement. We did have a lot of sightly different statements and wanted to change them one after another whenever a file gets touched. However that never happened. Instead people start to take the old/"wrong" statements to use as a template for new files. So unify all of them in one go. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>

* [S390] fix s390 assembler code alignmentsJan Glauber2011-07-241-6/+5
| | | | | | | | | | | | The alignment is missing for various global symbols in s390 assembly code. With a recent gcc and an instruction like stgrl this can lead to a specification exception if the instruction uses such a mis-aligned address. Specify the alignment explicitely and while add it define __ALIGN for s390 and use the ENTRY define to save some lines of code.

* [S390] correct address of _stext with CONFIG_SHARED_KERNEL=yMartin Schwidefsky2010-05-121-1/+1
| | | | | | | | | | | As of git commit 1844c9bc0b2fed3023551c1affe033ab38e90b9a head64.S/head31.S are not included in head.S anymore but build as an extra object. This breaks shared kernel support because the .org statement in head64.S/head31.S for CONFIG_SHARED_KERNEL=y will have a different effect. The end address of the head.text section in head.o will be added to the .org value, to compensate for this subtract 0x11000 to get the required value of 0x100000 again.

| | | | | | | | | | | | | | When the kernel is IPLed without the CLEAR option and switches to 64-bit, the high-order half of the registers might contain random values.

* [S390] Initialize __LC_THREAD_INFO early.Heiko Carstens2009-09-111-0/+1
| | | | | | | | | | | | | | | | | "lockdep: Fix backtraces" reveales a bug in early setup code: when lockdep tries to save a stack backtrace before setup_arch has been called the lowcore pointer for the current thread info pointer isn't initialized yet. However our save stack backtrace code relies on it. If the pointer isn't initialized the saved backtrace will have zero entries. lockdep however relies (correctly) on the fact that that cannot happen. A write access to some random memory region is the result. Fix this by initializing the thread info pointer early.

| | | | | | | | | | | | | | | | | | | From: Heiko Carstens <heiko.carstens@de.ibm.com> From: Carsten Otte <cotte@de.ibm.com> This lets us use defines for the magic bits in machine flags instead of using plain numbers all over the place. In addition on newer machines features/facilities are indicated by the result of the stfl instruction. So we use these bits instead of trying to execute new instructions and check wether we get an exception or not. Also the mvpg instruction is always available when in zArch mode, whereas the idte instruction is only available in zArch mode. This results in some minor optimizations.

* [S390] Fix tlb flushing with idte.Martin Schwidefsky2008-01-261-1/+1
| | | | | | | | | | | | The clear-by-asce operation of the idte instruction gets an asce (address-space-control-element) as argument to specify which TLBs need to get flushed. The current code passes a plain pointer to the start of the pgd without the additional bits which would make the pointer an asce. The current machines don't mind the difference but a future model might want to use the designation type control bits in the asce as a filter for the TLBs to flush.

* [S390] zfcpdump support.Michael Holzheu2007-04-271-1/+71
| | | | | | | | | | | | | | s390 machines provide hardware support for creating Linux dumps on SCSI disks. For creating a dump a special purpose dump Linux is used. The first 32 MB of memory are saved by the hardware before the dump Linux is booted. Via an SCLP interface, the saved memory can be accessed from Linux. This patch exports memory and registers of the crashed Linux to userspace via a debugfs file. For more information refer to Documentation/s390/zfcpdump.txt, which is included in this patch.

* [S390] Fixed handling of access register mode faults.Gerald Schaefer2007-03-051-3/+8
| | | | | | | | | | | | | | | | | | | Replaced check_user_space() + __check_access_register with the new check_space(). The old functions made wrong assumptions about kernel and user space when the kernel and user address spaces are switched (kernel in home space, user in primary/secondary space). Secondly the user process can switch to the accress register mode if it is running in primary or secondary mode. In addition it can load an arbitrary value to the access registers. If any other value than 0 for primary space or 1 for secondary space is loaded and memory is accessed using the base register related to the access register, the program should be terminated with a SIGSEGV. To achieve that the DUALD pointer in the DUCT and the PSALD pointer in the PASTE need to point to an array of 8 invalid access-list entries to get a ALEN-translation exception if an invalid alet is used.

| | | | | | | | | | | | | | Hopefully this will make it more maintainable and less error prone. Code makes use of search_exception_tables(). Since it calls this function before the kernel exeception table is sorted, there is an early call to sort_main_extable(). This way it's easy to use the already present infrastructure of fixup sections. Also this would allows to easily convert the rest of head[31|64].S into C code.

Add a system control to set the number of retries before a cpu is yielded. The reason for the spin lock retry is that the diagnose 0x44 that is used to give up the virtual cpu is quite expensive. For spin locks that are held only for a short period of time the costs of the diagnoses outweights the savings for spin locks that are held for a longer timer. The default retry count is 1000.

| | | | | | | | | | | | | | | | | The kernel takes a very long time to boot if the memory size is bigger then 32767 MB. The memory size is contained in a structure created by an sclp call. The kernel accesses the field with a LH instrution which performs a sign extension of a 16 bit word. In the case of a memory size with bit 2^15 set this results in a very large value and the memory detection just loops for a long time. In addition if more then 64 GB are used on a 64 bit system the memory size is read from an incorrect storage location. Use zero-extention to read the 16 bit memory size and the correct offset to read the 4 byte memory size on 64 bit.
