parisc: Enable TOC (transfer of contents) feature unconditionally Before this patch, the TOC code used a pre-allocated stack of 16kb for each possible CPU. That space overhead was the reason why the TOC feature wasn't enabled by default for 32-bit kernels. This patch rewrites the TOC code to use a per-cpu stack. That way we use much less memory now and as such we enable the TOC feature by default on all kernels. Additionally the dump of the registers and the stacktrace wasn't serialized, which led to multiple CPUs printing the stack backtrace at once which rendered the output unreadable. Now the backtraces are nicely serialized by a lock. Signed-off-by: Helge Deller <deller@gmx.de>

parisc: Rewrite light-weight syscall and futex code The parisc architecture lacks general hardware support for compare and swap. Particularly for userspace, it is difficult to implement software atomic support. Page faults in critical regions can cause processes to sleep and block the forward progress of other processes. Thus, it is essential that page faults be disabled in critical regions. For performance reasons, we also need to disable external interrupts in critical regions. In order to do this, we need a mechanism to trigger COW breaks outside the critical region. Fortunately, parisc has the "stbys,e" instruction. When the leftmost byte of a word is addressed, this instruction triggers all the exceptions of a normal store but it does not write to memory. Thus, we can use it to trigger COW breaks outside the critical region without modifying the data that is to be updated atomically. COW breaks occur randomly. So even if we have priviously executed a "stbys,e" instruction, we still need to disable pagefaults around the critical region. If a fault occurs in the critical region, we return -EAGAIN. I had to add a wrapper around _arch_futex_atomic_op_inuser() as I found in testing that returning -EAGAIN caused problems for some processes even though it is listed as a possible return value. The patch implements the above. The code no longer attempts to sleep with interrupts disabled and I haven't seen any stalls with the change. I have attempted to merge common code and streamline the fast path. In the futex code, we only compute the spinlock address once. I eliminated some debug code in the original CAS routine that just made the flow more complicated. I don't clip the arguments when called from wide mode. As a result, the LWS routines should work when called from 64-bit processes. I defined TASK_PAGEFAULT_DISABLED offset for use in the lws_pagefault_disable and lws_pagefault_enable macros. Since we now disable interrupts on the gateway page where necessary, it might be possible to allow processes to be scheduled when they are on the gateway page. Change has been tested on c8000 and rp3440. It improves glibc build and test time by about 10%. In v2, I removed the lws_atomic_xchg and and lws_atomic_store calls. I also removed the bug fixes that were not directly related to this patch. In v3, I removed the code to force interruptions from arch_futex_atomic_op_inuser(). It is always called with page faults disabled, so this code had no effect. In v4, I fixed a typo in depi_safe line. In v5, I moved the code to disable/enable page faults inside the spinlocks.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

parisc: Move thread_info into task struct This implements the CONFIG_THREAD_INFO_IN_TASK option. With this change: - before thread_info was part of the stack and located at the beginning of the stack - now the thread_info struct is moved and located inside the task_struct structure - the stack is allocated and handled like the major other platforms - drop the cpu field of thread_info and use instead the one in task_struct Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Sven Schnelle <svens@stackframe.org>
