* [SPARC]: Mark as emulating cmpxchg, add appropriate depends for DRM.Martin Habets2007-05-292-1/+8
| | | | | | | | | The DRM code depends on an atomic version of cmpxchg(), which is not available on sparc32. Since other platforms besides sparc32 have this issue a KCONFIG option is added for it.

* [SPARC64]: Fix _PAGE_EXEC_4U check in sun4u I-TLB miss handler.David S. Miller2007-05-291-2/+2
| | | | | | | | | | It was using an immediate _PAGE_EXEC_4U value in an 'and' instruction to perform the test. This doesn't work because the immediate field is signed 13-bit, this the mask being tested against the PTE was 0x1000 sign-extended to 32-bits instead of just plain 0x1000. Signed-off-by: David S.

* [SPARC]: Linux always started with 9600 8N1Jan Engelhardt2007-05-291-3/+3
| | | | | | | | | | | | | | | | The Linux kernel ignored the PROM's serial settings (115200,n,8,1 in my case). This was because mode_prop remained "ttyX-mode" (expected: "ttya-mode") due to the constness of string literals when used with "char *". Since there is no "ttyX-mode" property in the PROM, Linux always used the default 9600.

| | | | | | | | | | This is bug 8540 on bugzilla.kernel.org arch/sparc64/time.c contains references to assorted bq4802 stuff if CONFIG_PCI is not set, and compile fails. I #ifdef'ed out everything that looks PCI-ish in that file. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Eliminate NR_CPUS limitations.David S. Miller2007-05-296-16/+43
| | | | | | | | | | | | | | | | | | | | | | | | | Cheetah systems can have cpuids as large as 1023, although physical systems don't have that many cpus. Only three limitations existed in the kernel preventing arbitrary NR_CPUS values: 1) dcache dirty cpu state stored in page->flags on D-cache aliasing platforms. With some build time calculations and some build-time BUG checks on page->flags layout, this one was easily solved. 2) The cheetah XCALL delivery code could only handle a cpumask with up to 32 cpus set. Some simple looping logic clears that up too. 3) thread_info->cpu was a u8, easily changed to a u16. There are a few spots in the kernel that still put NR_CPUS sized arrays on the kernel stack, but that's not a sparc64 specific problem. Signed-off-by: David S. Miller <davem@davemloft.net>

* fix compat console unimap regressionHugh Dickins2007-05-261-8/+25
| | | | | | | | | | | | | | | | | | | | | | Why is it that since the 2f1a2ccb9c0de632ab07193becf5f7121794f6ae console UTF-8 fixes went into 2.6.22-rc1, the PowerMac G5 shows only inverse video question marks for the text on tty2-6? whereas tty1 is fine, and so is x86. No fault of that patch: by removing the old fallback behaviour, it reveals that 32-bit setfont running on 64-bit kernels has only really worked on the current console, the rest getting faked by that inadequate fallback. Bring the compat do_unimap_ioctl into line with the main one: PIO_UNIMAP and GIO_UNIMAP apply to the specified tty, not redirected to fg_console. Use the same checks, and most particularly, remember to check access_ok: con_set_unimap and con_get_unimap are using __get_user and __put_user. And the compat vt_check should ask for the same capability as the main one, CAP_SYS_TTY_CONFIG rather than CAP_SYS_ADMIN. Added in vt_ioctl's vc_cons_allocated check for safety, though failure may well be impossible.

Right now we'll block until the key manager resolves the route. That works for simple cases, but many folks would rather packets get silently dropped until the key manager resolves the IPSEC rules. We can't tell these folks to "set the socket non-blocking" because they don't have control over the non-block setting of things like the sockets used to resolve DNS deep inside of the resolver libraries in libc. With that in mind I coded up the patch below with some help from Herbert Xu which provides packet-drop behavior during larval state resolution, controllable via sysctl and off by default. This lays the framework to either: 1) Make this default at some point or... 2) Move this logic into xfrm{4,6}_policy.c and implement the ARP-like resolution queue we've all been dreaming of. The idea would be to queue packets to the policy, then once the larval state is resolved by the key manager we re-resolve the route and push the packets out. The packets would timeout if the rule didn't get resolved in a certain amount of time. Signed-off-by: David S. Miller <davem@davemloft.net>

POSIX do not defines behaviour for sys_setsockopt in case negative timeouts, but requires that setsockopt() shall fail with -EDOM if the send and receive timeout values are too big to fit into the timeout fields in the socket structure. In current implementation negative timeout can lead to error messages like "schedule_timeout: wrong timeout value". Proposed patch: - checks tv_usec and returns -EDOM if it is wrong - do not allows to set negative timeout values (sets 0 instead) and outputs ratelimited information message about such attempts.
