* Initialize eflags in fake frame to default value rather than random one.David Xu2003-03-081-0/+1
| | | | | | | | | | The random value sometimes causes macro CLKF_USERMODE to return true because PSL_VM bit is set and really shoudn't be, this causes statclock() to execute in wrong path, and further breaks KSE code and kernel crashes when executing threaded program.

| | | | | | | | | | | | | | check, mac_check_sysarch_ioperm(), permitting MAC security policy modules to control access to these interfaces. Currently, they protect access to IOPL on i386, and setting HAE on Alpha. Additional checks might be required on other platforms to prevent bypass of kernel security protections by unauthorized processes.

* Implemented "nooption" and "nomakeoption" config(8) tokens.Ruslan Ermilov2003-02-261-9/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed memory leak in the "nodevice" option implementation. Use these instead of sed(1) in MD NOTES. Use a single makefile (sys/conf/makeLINT.mk) to generate LINT for all architectures. (Previous versions missed the LINT dependency on Makefile, and i386 version also missed the dependency on ${NOTES}.) Fixed bugs in the previous NOTES conversion using the "nodevice" token and sed(1): - i386 LINT lost "device pst". - pc98 LINT lost SC_*, MAXCONS and KBD_DISABLE_KEYMAP_LOAD options, and got needless DPT_* options. - Added nooptions PPC_DEBUG, PPC_PROBE_CHIPSET, KBD_INSTALL_CDEV to sparc64 LINT so that it has a chance to config(8). This basically returns us to where we were before. Notes: svn path=/head/; revision=111582

* Cleanup of the d_mmap_t interface.Maxime Henrion2003-02-252-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Get rid of the useless atop() / pmap_phys_address() detour. The device mmap handlers must now give back the physical address without atop()'ing it. - Don't borrow the physical address of the mapping in the returned int. Now we properly pass a vm_offset_t * and expect it to be filled by the mmap handler when the mapping was successful. The mmap handler must now return 0 when successful, any other value is considered as an error. Previously, returning -1 was the only way to fail. This change thus accidentally fixes some devices which were bogusly returning errno constants which would have been considered as addresses by the device pager. - Garbage collect the poorly named pmap_phys_address() now that it's no longer used. - Convert all the d_mmap_t consumers to the new API. I'm still not sure wheter we need a __FreeBSD_version bump for this, since and we didn't guarantee API/ABI stability until 5.1-RELEASE.

We need to be able to call this stuff from outer edges of interrupt handlers for devices that have the ISR bits in pci config space. Making the bios code mpsafe was just too hairy. We had also stubbed it out some time ago due to there simply being too much brokenness in too many systems. This adds a leaf lock so that it is safe to use pci_read_config() and pci_write_config() from interrupt handlers. We still will use pcibios to do interrupt routing if there is no acpi..
