parisc: correctly display number of active CPUs

2013-11-07T21:29:05+00:00

In case we fail to power up other CPUs in a SMP system, the kernel
currently shows a wrong number of online CPUs. This change makes the
output more verbose on how many of the CPUs are online. Example:

CPU(s): 1 out of 2 PA8800 (Mako) at 900.000000 MHz online.

parisc: kernel: using strlcpy() instead of strcpy()

2013-06-01T12:29:01+00:00

'boot_args' is an input args, and 'boot_command_line' has a fix length.
So use strlcpy() instead of strcpy() to avoid memory overflow.

TTY:vt: convert remain take_over_console's users to do_take_over_console

2013-05-21T05:29:27+00:00

Impact:
1:convert all remain take_over_console to do_take_over_console
2:update take_over_console to do_take_over_console in comment

Commit dc9641895abb ("vt: delete unneeded functions
register_con_driver|take_over_console") delete take_over_console,
but forget to convert remain take_over_console's users to new API
do_take_over_console, this patch fix it.

parisc: fix partly 16/64k PAGE_SIZE boot

2013-05-06T21:08:32+00:00

This patch fixes partly PAGE_SIZEs of 16K or 64K by adjusting the
assembler PTE lookup code and the assembler TEMPALIAS code.  Furthermore
some data alignments for PAGE_SIZE have been limited to 4K (or less) to
not waste too much memory with greater page sizes. As a side note, the
palo loader can (currently) only handle up to 10 ELF segments which is
fixed with tighter aligning as well.

My testings indicated that the ldci command in the sba iommu coding
needed adjustment by the PAGE_SHIFT value and that the I/O PDIR Page
size was only set to 4K for my machine (C3000).

All this fixes partly the boot, but there are still quite some caching
problems left.  Examples are e.g. the symbios logic driver which is
failing:

sym0: <896> rev 0x7 at pci 0000:00:0f.0 irq 69
sym0: PA-RISC Firmware, ID 7, Fast-40, SE, parity checking
CACHE TEST FAILED: DMA error (dstat=0x81).sym0: CACHE INCORRECTLY CONFIGURED.

and the tulip network driver which doesn't seem to work correctly
either:

Sending BOOTP requests .net eth0: Setting full-duplex based on MII#1
link partner capability of 05e1
..... timed out!

Beside those kernel fixes glibc will need fixes too to be able to handle
>4K page sizes.

parisc: Add export.h to files needing EXPORT_SYMBOL/THIS_MODULE

2011-10-31T23:31:00+00:00

These guys were getting it implicitly via module.h before,
when module.h was everywhere.

parisc: remove dead BIO_VMERGE_BOUNDARY and BIO_VMERGE_MAX_SIZE definitions

2009-01-05T18:15:25+00:00

The block layer dropped the virtual merge feature
(b8b3e16cfe6435d961f6aaebcfd52a1ff2a988c5). BIO_VMERGE_BOUNDARY and
BIO_VMERGE_MAX_SIZE definitions are meaningless now.

parisc: initialize unwinder much earlier

2008-10-10T16:32:30+00:00

The unwinder was being initialized way too late to be any use
debugging early boot crashes. Instead of relying on module_init
initcalls to initialize it, let's do it explicitly as early as
we can.
