[IA64] Move include/asm-ia64 to arch/ia64/include/asm

2008-08-01T17:21:21+00:00

After moving the the include files there were a few clean-ups: 1) Some files used #include , changed to 2) Some comments alerted maintainers to look at various header files to make matching updates if certain code were to be changed. Updated these comments to use the new include paths. 3) Some header files mentioned their own names in initial comments. Just deleted these self references. Signed-off-by: Tony Luck

[IA64] Workaround for RSE issue

2008-05-27T20:24:39+00:00

Problem: An application violating the architectural rules regarding operation dependencies and having specific Register Stack Engine (RSE) state at the time of the violation, may result in an illegal operation fault and invalid RSE state. Such faults may initiate a cascade of repeated illegal operation faults within OS interruption handlers. The specific behavior is OS dependent. Implication: An application causing an illegal operation fault with specific RSE state may result in a series of illegal operation faults and an eventual OS stack overflow condition. Workaround: OS interruption handlers that switch to kernel backing store implement a check for invalid RSE state to avoid the series of illegal operation faults. The core of the workaround is the RSE_WORKAROUND code sequence inserted into each invocation of the SAVE_MIN_WITH_COVER and SAVE_MIN_WITH_COVER_R19 macros. This sequence includes hard-coded constants that depend on the number of stacked physical registers being 96. The rest of this patch consists of code to disable this workaround should this not be the case (with the presumption that if a future Itanium processor increases the number of registers, it would also remove the need for this patch). Move the start of the RBS up to a mod32 boundary to avoid some corner cases. The dispatch_illegal_op_fault code outgrew the spot it was squatting in when built with this patch and CONFIG_VIRT_CPU_ACCOUNTING=y Move it out to the end of the ivt. Signed-off-by: Tony Luck

[IA64] Synchronize RBS on PTRACE_ATTACH

2008-02-08T20:01:29+00:00

When attaching to a stopped process, the RSE must be explicitly synced to user-space, so the debugger can read the correct values. Signed-off-by: Petr Tesarik CC: Roland McGrath Signed-off-by: Tony Luck

[IA64] Synchronize kernel RSE to user-space and back

2008-02-08T20:01:18+00:00

This is base kernel patch for ptrace RSE bug. It's basically a backport from the utrace RSE patch I sent out several weeks ago. please review. when a thread is stopped (ptraced), debugger might change thread's user stack (change memory directly), and we must avoid the RSE stored in kernel to override user stack (user space's RSE is newer than kernel's in the case). To workaround the issue, we copy kernel RSE to user RSE before the task is stopped, so user RSE has updated data. we then copy user RSE to kernel after the task is resummed from traced stop and kernel will use the newer RSE to return to user.

[PATCH] Add regs_return_value() helper

2006-10-02T14:57:16+00:00

Add the regs_return_value() macro to extract the return value in an architecture agnostic manner, given the pt_regs. Other architecture maintainers may want to add similar helpers.
