[PATCH] ppc64: Fix wrong register mapping in mpic driver

2005-10-26T17:39:43+00:00

The mpic interrupt controller driver (used on G5 and early pSeries among
others) has a bug where it doesn't get the right virtual address for the
timer registers.  It causes the driver to poke at the MMIO space of
whatever has been mapped just next to it (ouch !) when initializing and
causes boot failures on some IBM machines.

[PATCH] ppc64: Fix typo bug in iSeries hash code

2005-10-21T19:24:41+00:00

This fixes a stupid typo bug in the iSeries hash table code.

When we place a hash PTE in the secondary bucket, instead of setting the
SECONDARY flag bit, as we should, we (redundantly) set the VALID flag.

This was introduced with the patch abolishing bitfields from the hash
table code.  Mea culpa, oops.  It hasn't been noticed until now because
in practice we don't hit the secondary bucket terribly often.

[PATCH] ppc64: Fix typo in time calculations

2005-10-21T19:17:43+00:00

This fixes a typo in the div128_by_32 function used in the timekeeping
calculations on ppc64.  If you look at the code it's quite obvious
that we need (rb + c) rather than (rb + b).  The "b" is clearly just a
typo.

[PATCH] ppc64: Fix error in vDSO 32 bits date

2005-10-20T06:04:30+00:00

The implementation of __kernel_gettimeofday() in the 32 bits vDSO has a
small bug (a typo actually) that will cause it to lose 1 bit of precision.
Not terribly bad but worth fixing.

[PATCH] ppc64: Fix G5 model in /proc/cpuinfo

2005-10-15T00:10:12+00:00

Andreas Schwab spotted that recent kernels broke reporting of the PowerMac
machine model in /proc/cpuinfo.  This fixes it.

[PATCH] ppc64: Add R_PPC64_TOC16 module reloc

2005-10-11T16:46:54+00:00

Newer gcc's are generating this relocation, so the module loader needs to
handle it.

[PATCH] ppc64: Fix PCI hotplug

2005-10-11T16:46:53+00:00

pSeries_irq_bus_setup is marked __devinit but references s7a_workaround
which is marked __initdata.

Depending on who got the memory for s7a_workaround (and if the value was
now positive), it was possible for PCI hotplugged devices to have 3
subtracted from their interrupt number.  This would happen randomly and
caused me much confusion :)

[PATCH] gfp flags annotations - part 1

2005-10-08T22:00:57+00:00

 - added typedef unsigned int __nocast gfp_t;

 - replaced __nocast uses for gfp flags with gfp_t - it gives exactly
   the same warnings as far as sparse is concerned, doesn't change
   generated code (from gcc point of view we replaced unsigned int with
   typedef) and documents what's going on far better.

[PATCH] ppc64: fix up()/down() usage for kprobe_mutex

2005-10-01T17:54:47+00:00

The incorrect kprobe_mutex usage on x86_64 had percolated to ppc64 too.
First noticed by Yanmin Zhang.

[PATCH] bogus BUILD_BUG_ON() in bpa_iommu

2005-09-30T15:42:24+00:00

BUILD_BUG_ON(1) is asking for trouble (and getting it) when used in that
manner - dead code elimination happens after we parse it and invalid
type is invalid type, dead code or not.

It might be version-dependent, but at least 4.0.1 refuses to accept
that.
