x86/amd: Add missing feature flag for fam15h models 10h-1fh processors

2012-01-26T11:06:38+00:00

That is the last one missing for those CPUs.

Others were recently added with commits

 fb215366b3c7320ac25dca766a0152df16534932
 (KVM: expose latest Intel cpu new features (BMI1/BMI2/FMA/AVX2) to guest)

and

 commit 969df4b82904a30fef19a67398a0c854d223ea67
 (x86: Report cpb and eff_freq_ro flags correctly)

x86/uv: Fix uv_gpa_to_soc_phys_ram() shift

2012-01-26T09:58:27+00:00

uv_gpa_to_soc_phys_ram() was inadvertently ignoring the
shift values.  This fix takes the shift into account.

x86, syscall: Need __ARCH_WANT_SYS_IPC for 32 bits

2012-01-19T20:57:09+00:00

In checkin

  303395ac3bf3 x86: Generate system call tables and unistd_*.h from tables

the feature macros in  were unified between 32 and 64
bits.  Unfortunately 32 bits requires __ARCH_WANT_SYS_IPC and this was
inadvertently dropped.

x86/UV2: Add accounting for BAU strong nacks

2012-01-17T08:09:59+00:00

This patch adds separate accounting of UV2 message "strong
nack's" in the BAU statistics.

x86/UV2: Work around BAU bug

2012-01-17T08:09:54+00:00

This patch implements a workaround for a UV2 hardware bug.
The bug is a non-atomic update of a memory-mapped register. When
hardware message delivery and software message acknowledge occur
simultaneously the pending message acknowledge for the arriving
message may be lost.  This causes the sender's message status to
stay busy.

Part of the workaround is to not acknowledge a completed message
until it is verified that no other message is actually using the
resource that is mistakenly recorded in the completed message.

Part of the workaround is to test for long elapsed time in such
a busy condition, then handle it by using a spare sending
descriptor. The stay-busy condition is eventually timed out by
hardware, and then the original sending descriptor can be
re-used. Most of that logic change is in keeping track of the
current descriptor and the state of the spares.

The occurrences of the workaround are added to the BAU
statistics.

x86/UV2: Fix new UV2 hardware by using native UV2 broadcast mode

2012-01-17T08:09:51+00:00

Update the use of the Broadcast Assist Unit on SGI Altix UV2 to
the use of native UV2 mode on new hardware (not the legacy mode).

UV2 native mode has a different format for a broadcast message.
We also need quick differentiaton between UV1 and UV2.

mce: fix warning messages about static struct mce_device

2012-01-17T01:08:42+00:00

When suspending, there was a large list of warnings going something like:

	Device 'machinecheck1' does not have a release() function, it is broken and must be fixed

This patch turns the static mce_devices into dynamically allocated, and
properly frees them when they are removed from the system.  It solves
the warning messages on my laptop here.

x86: Get rid of dubious one-bit signed bitfield

2012-01-16T08:39:54+00:00

This very noisy sparse warning appears on almost every file in
the kernel:

  CHECK   init/main.c
  arch/x86/include/asm/thread_info.h:43:55: error: dubious one-bit
  signed bitfield arch/x86/include/asm/thread_info.h:44:46: error:
  dubious one-bit signed bitfield

Sparse is right and this patch changes sig_on_uaccess_error and
uaccess_err flags to unsigned type and thus fixes the warning.
