* [S390] virtual cpu accounting vs. machine checks.Martin Schwidefsky2006-06-29
| | | | | | | | | | | | | | | | If a machine checks interrupts the external or the i/o interrupt handler before they have completed the cpu time calculations, the accounting goes wrong. After the cpu returned from the machine check handler to the interrupted interrupt handler, a negative cpu time delta can occur. If the accumulated cpu time in lowcore is small enough this value can get negative as well. The next jiffy interrupt will pick up that negative value, shift it by 12 and add the now huge positive value to the cpu time of the process. To solve this the machine check handler is modified not to change any of the timestamps in the lowcore if the machine check interrupted kernel context.

* [S390] console_unblank woes.Martin Schwidefsky2006-06-29
| | | | | | | | | | | | | The software watchdog calls machine_restart from a timer function. The s390 machine_restart calls console_unblank to flush the console output. This is needed for panic to get the panic message printed. If console_unblank is called in interrupt a BUG is triggered in acquire_console_sem. That makes the software watchdog panic instead of restarting the machine. To get around this problem the call to console_unblank is made conditionally on !in_interrupt() || oops_in_progress.

* [S390] memory detection.Heiko Carstens2006-06-29

* [S390] incomplete stack traces.Heiko Carstens2006-06-29
| | | | | | | | | | | show_stack() passes a pointer to the current stack frame to show_trace(). Because of tail call optimization the pointer doesn't point to the original stack frame anymory and therefore traces are wrong. Don't pass the pointer of the current stack frame to show_trace(). Instead let show_trace() calculate the pointer on its own. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

| * [ARM] nommu: backtrace code must not reference a discarded sectionRussell King2006-06-28
| | | | | | | | | | | | | | | | | | The code in "1007:" is in the .fixup section, which in the mmuless case is discarded. Since this code is referenced from the .text section, it causes an link error. Move this code into the .text section instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] nommu: Initial uCLinux support for MMU-based CPUsHyok S. Choi2006-06-28
| | | | | | | | | | | | | | | | | | | | In noMMU mode, various of functions which are defined in mm/proc-*.S is not valid or needed to be avoided. i.g. switch_mm is not needed, just returns and this makes the I & D caches are valid which shows great improvement of performance including task switching and IPC.

| | | | | | | | | | | | | | | | | | Hyok says Intel Xscale is not currently supported by uCLinux. Rather than adding #error statements to the Xscale support files and causing !MMU+Xscale configurations to fail to build, prevent Xscale-based machines from being selected in !MMU mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove fault-armv.o, mmap.o and mm-armv.o from uclinux builds - these are concerned with MMU-ful operations, and as such are redundant for uclinux. Since this also removes iotable_init() and iotable_init() is used extensively in the platform support files, just make it a no-op. Based upon a couple of patches by Hyok. Signed-off-by: Hyok S.

| * [ARM] nommu: add stubs for ioremap and friendsRussell King2006-06-28
| | | | | | | | | | | | | | | | | | | | | | nommu doesn't have any form of remapping support, so ioremap, etc become stubs which just return the casted address, doing nothing else. Move ioport_map(), ioport_unmap(), pci_iomap(), pci_iounmap() into a separate file which is always built. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] nommu: avoid selecting TLB and CPU specific copy codeHyok S. Choi2006-06-28
| | | | | | | | | | | | | | | | | | | | | | Since uclinux doesn't make use of the TLB, including the TLB maintainence and CPU-optimised copypage functions does not make sense. Remove them.

| * [ARM] nommu: uaccess tweaksRussell King2006-06-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MMUless systems have only one address space for all threads, so both the usual access_ok() checks, and the exception handling do not make much sense. Hence, discard the fixup and exception tables at link time, use memcpy/memset for the user copy/clearing functions, and define the permission check macros to be constants. Some of this patch was derived from the equivalent patch by Hyok S. Choi. Signed-off-by: Hyok S. Choi <hyok.choi@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
