      [PATCH] ppc/ppc64: Cleanup PPC970 CPU initialization · 80d62805
      Benjamin Herrenschmidt authored
      This cleans up the code used to initialize the 970 CPU.
      
      More specifically, it adds support for the 970FX, makes sure we don't
      touch registers we aren't supposed to when running in LPAR mode, and
      stop blindly zeroing out HID4 and HID5, we just clear the bits we really
      want clear in there and leave the rest to the firmware.

      [SERIAL] default to serial console when possible · f34acba3
      Bjorn Helgaas authored
      Patch from Bjorn Helgaas
      
      This adds efi_uart_console_only() so we can default to using a serial
      console if the EFI console path only contains UARTs.

      [SERIAL] 8250_hcdp needs irq sharing · 7c6d39f1
      Alex Williamson authored
      Patch from Alex Williamson
      
      Here's a trivial patch that makes 8250_hcdp setup the correct flags
      when IRQ sharing is enabled for serial ports.
      
      The HCDP table tells us if the device is a PCI UART.  We can use this
      to set the shared interrupt flag as well as program the interrupt with
      the correct polarity/trigger (should get rid of "changing vector <x>
      from IO-SAPIC-edge to IO-SAPIC-level" messages at bootup).  This also
      allows non-PCI UARTs to be left un-shareable, which is likely much
      more safe (edge triggered).
      
      The bit that I'm keying on is still part of the older 1.0a HCDP spec,
      so should be implemented (it was on all the boxes I tested).  If
      there's firmware out there that doesn't set this bit or the interrupt
      supported flag, the HCDP UART may run in polling mode, but should
      still be functional.

      Patch from Daniel Ritz.
      
      This patch clears an almost undocumented EnE specific test register
      that makes sound on RME Hammerfall DSP Carbus work...should even work
      after suspend.

      [PATCH] report size of printk buffer · 70d5032e
      Andrew Morton authored
      From: <Andries.Brouwer@cwi.nl>
      
      In the old days the printk log buffer had a constant size, and dmesg asked
      for the 4096, later 8192, later 16384 bytes in there.  These days the
      printk log buffer has variable size, and it is not easy for dmesg to do the
      right thing, especially when doing a "read and clear".  The patch below
      adds a syslog subfuntion that reports the buffer size.

      Move error handling to capture all three possible error conditions on

      [PATCH] ppc32: Updated boot fix · 3bbadbdf
      Paul Mackerras authored
      This fixes booting on some PPC32 machines, notably CHRP and powermac
      machines.  This is a modified version of Tom Rini's patch that addresses
      the concerns I had with it.
      
      The problem was that the linker script was getting included in the list
      of things that got put together to make some of the sorts of bootable
      images that we produce.  This removes ld.script in cases where it wasn't
      appropriate and changes the rules in others so that although we have the
      dependency on ld.script, it doesn't get included in the list of things
      to link.

      [PATCH] ppc64: Use slbie, not slbia in hugepage code · 59fe352b
      David Gibson authored
      On PPC64, when we prepare segments below 4G for use with hugepages, we
      need to flush their entries from the SLB, in case SLB entries
      specifying normal pages were already present.
      
      Previously we did that by flushing the entire SLB, the patch below
      changes this to individually flush each necessary segment with slbie.
      The new version may well be slightly faster, but the real reason for
      it is so that this code path doesn't need to be changed to reinstate
      any bolted SLB entries, if we add them.  The existing version has
      already caused problems (read, crashes) when combined with some
      patches that add bolted SLB entries.
