2007-05-29[SPARC64]: Fill holes in hypervisor APIs and fix KTSB registry.David S. Miller
Several interfaces were missing and others misnumbered or improperly documented. Also, make sure to check the return value when registering the kernel TSBs with the hypervisor. This helped to find the 4MB kernel TSB alignment bug fixed in a previous changeset. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-05-29[SPARC64]: Fix two bugs wrt. kernel 4MB TSB.David S. Miller
1) The TSB lookup was not using the correct hash mask. 2) It was not aligned on a boundary equal to it's size, which is required by the sun4v Hypervisor. wasn't having it's return value checked, and that bug will be fixed up as well in a subsequent changeset.

2007-05-29[SPARC64]: Fix _PAGE_EXEC_4U check in sun4u I-TLB miss handler.David S. Miller
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. Miller <davem@davemloft.net>
2007-05-29[SPARC64]: arch/sparc64/time.c doesn't compile on Ultra 1 (no PCI)Horst H. von Brand
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>
2007-05-29[SPARC64]: Eliminate NR_CPUS limitations.David S. Miller
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>

2007-05-29[SPARC64]: PCI device scan is way too verbose by default.David S. Miller
These messages were very useful when bringing up the OBP based PCI device scan code, but it's just a lot of noise every bootup now especially on big machines. The messages can be re-enabled via 'ofpci_debug=1' on the kernel command line. Signed-off-by: David S. Miller <davem@davemloft.net>

Section mismatch: reference to .init.text:acpi_find_rsdp (between 'acpi_get_sysname' and 'acpi_request_vector') acpi_get_sysname() needs to call the __init function acpi_find_rsdp, but it doesn't have the __init attribute itself, hence the warning. Luckily it is only called from machvec_init() which has __init attribute, so the fix is to define acpi_get_sysname() as __init too. Signed-off-by: Tony Luck <tony.luck@intel.com>

Sam's recent change in 7664709b44a13e2e0b545e2dd8e7b8797a1748dc broke things for us because we ended up with *(.text.*) before *(.text), whereas previously *(.text) was first. This was important because the start of the text section contains the kernel entry point.

2007-05-21x86_64: vsyscall time() fixjohn stultz
The vsyscall time() function basically returns the second portion of xtime directly. This however means that there is about a ticks worth of time each second where time() will return a second value less then what gettimeofday() does. Additionally, this window where vtime() is behind vgettimeofday() grows when dynticks is enabled, so its probably good to get this in before dynticks lands. Big thanks to Sripathi for noticing this issue and creating a test case to work with!
