* [ARM] nwfpe: fix 'floatx80_is_nan' sparse warningBen Dooks2009-05-15
| | | | | | | | | | | | | The symbol 'floatx80_is_nan' prototype was defined locally in fpa11_cprt.c when it was built outside the file in softfloat-specialisze. Move this into softfloat.h to fix the following sparse warning: softfloat-specialize:276:6: warning: symbol 'floatx80_is_nan' was not declared. Should it be static? Signed-off-by: Ben Dooks <ben-linux@fluff.org>
* [ARM] nwfpe: Add decleration for ExtendedCPDOBen Dooks2009-05-15
| | | | | | | | | Add header file decleration for 'ExtendedCPDO' in fpa11.h to stop the following sparse warning: extended_cpdo.c:90:14: warning: symbol 'ExtendedCPDO' was not declared. Should it be static? Signed-off-by: Ben Dooks <ben-linux@fluff.org>

* Convert files to UTF-8 and some cleanupsJan Engelhardt2007-10-19
| | | | | | | | | | | | | | | | | | * Convert files to UTF-8. * Also correct some people's names (one example is Eißfeldt, which was found in a source file. Given that the author used an ß at all in a source file indicates that the real name has in fact a 'ß' and not an 'ss', which is commonly used as a substitute for 'ß' when limited to 7bit.) * Correct town names (Goettingen -> Göttingen) * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313) Signed-off-by: Jan Engelhardt <jengelh@gmx.de> Signed-off-by: Adrian Bunk <bunk@kernel.org>
* Replace __attribute_pure__ with __pureRalf Baechle2007-10-18

* [ARM] 4581/1: Fix the conditional execution of the NWFPE instructionsCatalin Marinas2007-10-12
| | | | | | | | | | Starting with ARMv7-A, conditional execution of undefined instructions can trigger an exception even if the condition check fails. This patch modifies the NWFPE support to check the condition before emulating the instruction.

* [ARM] Remove MODE_(SVC|IRQ|FIQ|USR) and DEFAULT_FIQRussell King2006-06-25
| | | | | | | DEFAULT_FIQ was entirely unused. MODE_* are just redefinitions of *_MODE. Use *_MODE instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Add thread_notify infrastructureRussell King2006-06-22
| | | | | | | | | | | | | Some machine classes need to allow VFP support to be built into the kernel, but still allow the kernel to run even though VFP isn't present. Unfortunately, the kernel hard-codes VFP instructions into the thread switch, which prevents this being run-time selectable. Solve this by introducing a notifier which things such as VFP can hook into to be informed of events which affect the VFP subsystem (eg, creation and destruction of threads, switches between threads.)

* [ARM] 3118/1: fix and reenable nwfpe extended precision emulation for big-endianLennert Buytenhek2005-11-07
| | | | | | | | | | | | | Patch from Lennert Buytenhek nwfpe extended precision emulation used to be broken on big-endian and was therefore disabled. This patch fixes nwfpe so that it copies extended precision floats to/from userspace in the proper word order (similar to patch #2046, see the description of that patch for an explanation) and reenables the Kconfig option.

* [ARM] 3117/1: nwfpe kernel memory info leakLennert Buytenhek2005-11-07
| | | | | | | | | | | | | | | Patch from Lennert Buytenhek The routine that nwfpe uses for converting floats/doubles to extended precision fails to zero two bytes of kernel stack. This is not immediately obvious, as the floatx80 structure has 16 bits of implicit padding (by design.) These two bytes are copied to userspace when an stfe is emulated, causing a possible info leak. Make the padding explicit and zero it out in the relevant places. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [PATCH] ARM: 2837/2: Re: ARM: Make NWFPE preempt safeRichard Purdie2005-08-03
| | | | | | | | | | | | | | Patch from Richard Purdie NWFPE used global variables which meant it wasn't safe for use with preemptive kernels. This patch removes them and communicates the information between functions in a preempt safe manner. Generation of some exceptions was broken and this has also been corrected. Tests with glibc's maths test suite show no change in the results before/after this patch. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [PATCH] ARM: Remove global nwfpe register variableRussell King2005-07-17
| | | | | | | | | | | | | | | Recent changes to nwfpe broke the build with some gcc versions: In file included from arch/arm/nwfpe/softfloat.c:33: arch/arm/nwfpe/fpa11.h:32: global register variable follows a function definition make[1]: *** [arch/arm/nwfpe/softfloat.o] Error 1 Since we now ensure that the kernel stack is empty when returning to user space, we can now access the userspace registers with reference to the kernel stack using current_thread_info(), rather than remembering the stack pointer at the time nwfpe was called.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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. Let it rip!
