alpha: Use new generic strncpy_from_user() and strnlen_user()

2012-08-19T15:41:18+00:00

Similar to x86/sparc/powerpc implementations except:
1) we implement an extremely efficient has_zero()/find_zero()
   sequence with both prep_zero_mask() and create_zero_mask()
   no-operations.
2) Our output from prep_zero_mask() differs in that only the
   lowest eight bits are used to represent the zero bytes
   nevertheless it can be safely ORed with other similar masks
   from prep_zero_mask() and forms input to create_zero_mask(),
   the two fundamental properties prep_zero_mask() must satisfy.

Tests on EV67 and EV68 CPUs revealed that the generic code is
essentially as fast (to within 0.5% of CPU cycles) of the old
Alpha specific code for large quadword-aligned strings, despite
the 30% extra CPU instructions executed.  In contrast, the
generic code for unaligned strings is substantially slower (by
more than a factor of 3) than the old Alpha specific code.

ipc: use Kconfig options for __ARCH_WANT_[COMPAT_]IPC_PARSE_VERSION

2012-07-31T00:25:21+00:00

Rather than #define the options manually in the architecture code, add
Kconfig options for them and select them there instead.  This also allows
us to select the compat IPC version parsing automatically for platforms
using the old compat IPC interface.

Pull timer updates from Thomas Gleixner.

Various trivial conflict fixups in arch Kconfig due to addition of
unrelated entries nearby.  And one slightly more subtle one for sparc32
(new user of GENERIC_CLOCKEVENTS), fixed up as per Thomas.

Pull smp hotplug cleanups from Thomas Gleixner:
 "This series is merily a cleanup of code copied around in arch/* and
  not changing any of the real cpu hotplug horrors yet.  I wish I'd had
  something more substantial for 3.5, but I underestimated the lurking
  horror..."

alpha: VGA_HOSE depends on VGA_CONSOLE

2012-05-02T19:54:05+00:00

arch/alpha/kernel/console.c:locate_and_init_vga uses vga_con, causing
build failures if VGA_CONSOLE was not set and MARVEL, TITAN, DP264, or
GENERIC alpha system types were set.

alpha: switch to GENERIC_PCI_IOMAP

2011-11-28T19:13:01+00:00

alpha copied pci_iomap from generic code to avoid
pulling the rest of iomap.c in.  Since that's in
a separate file now, we can reuse the common implementation.

The only difference is handling of nocache flag,
that turns out to be done correctly by the
generic code since arch/alpha/include/asm/io.h
defines ioremap_nocache same as ioremap.
