* [PATCH] FRV: improve FRV's use of generic IRQ handlingDavid Howells2006-09-264-69/+53
| | | | | | | | | | | | | | | | | | | | | | | Improve FRV's use of generic IRQ handling: (*) Use generic_handle_irq() rather than __do_IRQ() as the latter is obsolete. (*) Don't implement enable() and disable() ops as these will fall back to using unmask() and mask(). (*) Provide mask_ack() functions to avoid a call each to mask() and ack(). (*) Make the cascade handlers always return IRQ_HANDLED. (*) Implement the mask() and unmask() functions in the same order as they're listed in the ops table.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | - When setting a sighandler using sigaction() call, if the flag SA_ONSTACK is set and no alternate stack is provided via sigaltstack(), the kernel still try to install the alternate stack. This behavior is the opposite of the one which is documented in Single Unix Specifications V3. - Also when setting an alternate stack using sigaltstack() with the flag SS_DISABLE, the kernel try to install the alternate stack on signal delivery. These two use cases makes the process crash at signal delivery.

* [PATCH] No arch-specific strpbrk implementationsKyle McMartin2006-04-111-1/+0
| | | | | | | | | | | | | | | While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't being exported from lib/string.c. Investigating further, I noticed a changeset that removed its export and added it to _ksyms.c on a few more architectures. The justification was that "other arches do it." I think this is wrong, since no architecture currently defines __HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it themselves. Therefore, consolidate the export to lib/string.c.

* [PATCH] frv: define MMU mode specific syscalls as 'cond_syscall' and clean ↵Hyok S. Choi2006-04-111-16/+10
| | | | | | | | | | | | | | | | | | | up unneeded macros For some architectures, a few syscalls are not linked in noMMU mode. In that case, the MMU depending syscalls are needed to be defined as 'cond_syscall'. For example, ARM architecture selectively links sys_mlock by the mode configuration. In case of FRV, it has been managed by #ifdef CONFIG_MMU macro in arch/frv/kernel/entry.S. However these conditional macros are just duplicates if they were defined as cond_syscall. Compilation test is done with FRV toolchains for both of MMU and noMMU mode. Signed-off-by: Hyok S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we stop allocating percpu memory for not-possible CPUs we must not touch the percpu data for not-possible CPUs at all. The correct way of doing this is to test cpu_possible() or to use for_each_cpu(). This patch is a kernel-wide sweep of all instances of NR_CPUS. I found very few instances of this bug, if any. But the patch converts lots of open-coded test to use the preferred helper macros.

* [PATCH] FRV: Use virtual interrupt disablementDavid Howells2006-02-146-55/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the FRV arch use virtual interrupt disablement because accesses to the processor status register (PSR) are relatively slow and because we will soon have the need to deal with multiple interrupt controls at the same time (separate h/w and inter-core interrupts). The way this is done is to dedicate one of the four integer condition code registers (ICC2) to maintaining a virtual interrupt disablement state whilst inside the kernel. This uses the ICC2.Z flag (Zero) to indicate whether the interrupts are virtually disabled and the ICC2.C flag (Carry) to indicate whether the interrupts are physically disabled. ICC2.Z is set to indicate interrupts are virtually disabled. ICC2.C is set to indicate interrupts are physically enabled. Under normal running conditions Z==0 and C==1. Disabling interrupts with local_irq_disable() doesn't then actually physically disable interrupts - it merely sets ICC2.Z to 1. Should an interrupt then happen, the exception prologue will note ICC2.Z is set and branch out of line using one instruction (an unlikely BEQ). Here it will physically disable interrupts and clear ICC2.C. When it comes time to enable interrupts (local_irq_enable()), this simply clears the ICC2.Z flag and invokes a trap #2 if both Z and C flags are clear (the HI integer condition). This can be done with the TIHI conditional trap instruction. The trap then physically reenables interrupts and sets ICC2.C again. Upon returning the interrupt will be taken as interrupts will then be enabled. Note that whilst processing the trap, the whole exceptions system is disabled, and so an interrupt can't happen till it returns. If no pending interrupt had happened, ICC2.C would still be set, the HI condition would not be fulfilled, and no trap will happen. Saving interrupts (local_irq_save) is simply a matter of pulling the ICC2.Z flag out of the CCR register, shifting it down and masking it off. This gives a result of 0 if interrupts were enabled and 1 if they weren't. Restoring interrupts (local_irq_restore) is then a matter of taking the saved value mentioned previously and XOR'ing it against 1. If it was one, the result will be zero, and if it was zero the result will be non-zero. This result is then used to affect the ICC2.Z flag directly (it is a condition code flag after all). An XOR instruction does not affect the Carry flag, and so that bit of state is unchanged. The two flags can then be sampled to see if they're both zero using the trap (TIHI) as for the unconditional reenablement (local_irq_enable). This patch also: (1) Modifies the debugging stub (break.S) to handle single-stepping crossing into the trap #2 handler and into virtually disabled interrupts. (2) Removes superseded fixup pointers from the second instructions in the trap tables (there's no a separate fixup table for this). (3) Declares the trap #3 vector for use in .org directives in the trap table. (4) Moves irq_enter() and irq_exit() in do_IRQ() to avoid problems with virtual interrupt handling, and removes the duplicate code that has now been folded into irq_exit() (softirq and preemption handling). (5) Tells the compiler in the arch Makefile that ICC2 is now reserved. (6) Documents the in-kernel ABI, including the virtual interrupts. (7) Renames the old irq management functions to different names.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handle TIF_RESTORE_SIGMASK as added by David Woodhouse's patch entitled: [PATCH] 2/3 Add TIF_RESTORE_SIGMASK support for arch/powerpc [PATCH] 3/3 Generic sys_rt_sigsuspend It does the following: (1) Declares TIF_RESTORE_SIGMASK for FRV. (2) Invokes it over to do_signal() when TIF_RESTORE_SIGMASK is set. (3) Makes do_signal() support TIF_RESTORE_SIGMASK, using the signal mask saved in current->saved_sigmask. (4) Discards sys_rt_sigsuspend() from the arch, using the generic one instead. (5) Makes sys_sigsuspend() save the signal mask and set TIF_RESTORE_SIGMASK rather than attempting to fudge the return registers. (6) Makes sys_sigsuspend() return -ERESTARTNOHAND rather than looping intrinsically. (7) Makes setup_frame(), setup_rt_frame() and handle_signal() return 0 or -EFAULT rather than true/false to be consistent with the rest of the kernel. Due to the fact do_signal() is then only called from one place: (8) Make do_signal() no longer have a return value is it was just being ignored; force_sig() takes care of this. (9) Discards the old sigmask argument to do_signal() as it's no longer necessary. This patch depends on the FRV signalling patches as well as the sys_rt_sigsuspend patch.

* | [PATCH] "tiny-make-id16-support-optional" fixesAdrian Bunk2006-01-101-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems the "make UID16 support optional" patch was checked when it edited the -tiny tree some time ago, but it wasn't checked whether it still matches the current situation when it was submitted for inclusion in -mm. This patch fixes the following bugs: - ARCH_S390X does no longer exist, nowadays this has to be expressed through (S390 && 64BIT) - in five architecture specific Kconfig files the UID16 options weren't removed Additionally, it changes the fragile negative dependencies of UID16 to positive dependencies (new architectures are more likely to not require UID16 support).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a number of miscellanous items: (1) Declare lock sections in the linker script. (2) Recurse in the correct manner in the arch makefile. (3) asm/bug.h requires asm/linkage.h to be included first. One C file puts asm/bug.h first. (4) Add an empty RTC header file to avoid missing header file errors. (5) sg_dma_address() should use the dma_address member of a scatter list. (6) Add trivial pci_unmap support. (7) Add pgprot_noncached() (8) Discard u_quad_t. (9) Use ~0UL rather than ULONG_MAX in unistd.h in case the latter isn't declared. (10) Add an empty VGA header file to avoid missing header file errors. (11) Add an XOR header file to use the generic XOR stuff.
