Presently the LparMap, one of the structures the kernel shares with the legacy iSeries hypervisor has a fixed offset address in head.S. This patch changes this so the LparMap is a normally initialized structure, without fixed address. This allows us to use macros to compute some of the values in the structure, which wasn't previously possible because the assembler always uses signed-% which gets the wrong answers for the computations in question. Unfortunately, a gcc bug means that doing this requires another structure (hvReleaseData) to be initialized in asm instead of C, but on the whole the result is cleaner than before. Signed-off-by:

PPC64 machines before Power4 need a segment table page allocated for each CPU. Currently these are allocated statically in a big array in head.S for all CPUs. The segment tables need to be in the first segment (so do_stab_bolted doesn't take a recursive fault on the stab itself), but other than that there are no constraints which require the stabs for the secondary CPUs to be statically allocated. This patch allocates segment tables dynamically during boot, using lmb_alloc() to ensure they are within the first 256M segment. This reduces the kernel image size by 192k... Tested on RS64 iSeries, POWER3 pSeries, and POWER5. Signed-off-by:

genrtc.c won't compile on ppc64. Seems that ppc32 does support it though? We do this wrong btw - we should be selecting GEN_RTC in each arch/xxx/Kconfig. Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by:

This bites me all day when I use our default config for ppc64. We use a patch to fix the compile errors and provide the CONFIG_MAC_EMUMOUSEBTN functionality (which is behind CONFIG_INPUT_ADBHID). But Benh doesnt like it. http://ozlabs.org/pipermail/linuxppc64-dev/2005-March/003423.html Just hide all the ADB parts from via-pmu on ppc64 instead. drivers/macintosh/adbhid.c: In function `adbhid_init': drivers/macintosh/adbhid.c:1199: error: `_MACH_chrp' undeclared (first use in this function) drivers/macintosh/adbhid.c:1199: error: (Each undeclared identifier is reported only once drivers/macintosh/adbhid.c:1199: error: for each function it appears in.)

Typo bug that was using PCI1 defines instead of PCI2 when setting up the second PCI bus controller on 85xx based systems. This hasn't been a real issue since currently the PCI2 sizes are the same as the PCI1 sizes for currently supported boards. Thanks to Andrew Klossner @ Xerox for point this out. Signed-off-by:

On PPC 8xx, the DataTLBMiss handler does not jump directly to the page fault handler, as was the case in v2.4. It instead loads an invalid TLB which causes a subsequent DataTLBError exception. The comment on top of it haven't been update to reflect the change, though. Signed-off-by:

The UARTs on the MPC824x are unique devices and really shouldn't be thought of as a DUART. In addition, if both UARTs are in use we need to configure the part to enable the 2nd UART since the pins for the UARTs are multiplexed. Adds support to run the 824x Sandpoint with both UARTs if desired. Signed-off-by:

Originally __free_pages_bulk used the relative page number within a zone to define its buddies. This meant that to maintain the "maximally aligned" requirements (that an allocation of size N will be aligned at least to N physically) zones had to also be aligned to 1<<MAX_ORDER pages. When __free_pages_bulk was updated to use the relative page frame numbers of the free'd pages to pair buddies this released the alignment constraint on the 'left' edge of the zone. This allows _either_ edge of the zone to contain partial MAX_ORDER sized buddies. These simply never will have matching buddies and thus will never make it to the 'top' of the pyramid. The patch below removes a now redundant check ensuring that the mem_map was aligned to MAX_ORDER. Signed-off-by:

Add support for the MRi PCIDS1 dual port serial card. This card is a little controversial since it is the subject of a PCI vendor/device ID clash. (See http://www.ussg.iu.edu/hypermail/linux/kernel/0303.1/0516.html). I have for now just used the hex ID 0x950a. The divisor was part calculated part iterated, so may not be exactly correct (but works for me at all settings between 300 - 115300 bps). Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by:

Fix bug identifued by Richard Purdie <rpurdie@rpsys.net>. oprofile calls check_user_page_readable() from interrupt context, so we deadlock over various VFS locks. But check_user_page_readable() doesn't imply either a read or a write of the page's contents. Change __follow_page() so that check_user_page_readable() can tell __follow_page() that we're not accessing the page's contents, and use that info to avoid the troublesome lock-takings. Also, make follow_page() inline for the single callsite in memory.c to save a bit of stack space. Signed-off-by:

Oliver Paukstadt from our test department is testing the xip patches in Linus' git-tree. He found a problem that shows when reading a file that contains sparse blocks (holes) on a -o xip mounted ext2 filesystem: the BUG_ON() in fs/ext2/xip.c:40 triggers where it should not. The problem was introduced by a cleanup in my previous patch, this patch fixes it. Signed-off-by:

This patch fixes a microcode lockup in my CD-ROM adapters when a blank CD is inserted. However, do not try to burn CDs yet! I'm pretty sure that trying it will end in coasters. - Fix a few cases where we were unable to resynchronize with replies for previous commands. The main thing is to keep reading replies in case of a stall. This is done with the new state CLRRS. - Since I am forgetting the basic state machine already, document it. - Move counter increments in the looping path in its own function. - Fix a harmless buglet in case CSW read fails to submit: do not override state. - Implement the Alan Stern's idea for adaptive signature checking.
