2008-10-30MIPS: Sort out CPU type to name translation.Ralf Baechle
As noticed by David Daney <ddaney@caviumnetworks.com>, the old long switch statement did not comply with the Linux C coding style. It was also yet another place of code to be changed when adding a new processor type leading to annoying bugs for example in /proc/cpuinfo. Fixed by moving the setting of the CPU type string into the core of the probing code and a few BUG_ON() test to ensure the CPU probing code indeed did its job and removing multiple now redundant tests.

2008-10-30MIPS: Switch FPU emulator trap to BREAK instruction.Ralf Baechle
Arguably using the address error handler has always been ugly.

2008-10-28x86, gart: fix gart detection for Fam11h CPUsJoerg Roedel
Impact: fix AMD Family 11h boot hangs / USB device problems The AMD Fam11h CPUs have a K8 northbridge. This northbridge is different from other family's because it lacks GART support (as I just learned). But the kernel implicitly expects a GART if it finds an AMD northbridge. Fix this by removing the Fam11h northbridge id from the scan list of K8 northbridges. This patch also changes the message in the GART driver about missing K8 northbridges to tell that the GART is missing which is the correct information in this case.

2008-10-28x86, kdump: fix invalid access on i386 sparsememKen'ichi Ohmichi
Impact: fix kdump crash on 32-bit sparsemem kernels Since linux-2.6.27, kdump has failed on i386 sparsemem kernel. 1st-kernel gets a panic just before switching to 2nd-kernel. The cause is that a kernel accesses invalid mem_section by page_to_pfn(image->swap_page) at machine_kexec(). image->swap_page is allocated if kexec for hibernation, but it is not allocated if kdump. So if kdump, a kernel should not access the mem_section corresponding to image->swap_page. The attached patch fixes this invalid access.

2008-10-28KVM: Fix guest shared interrupt with in-kernel irqchipSheng Yang
Every call of kvm_set_irq() should offer an irq_source_id, which is allocated by kvm_request_irq_source_id(). Based on irq_source_id, we identify the irq source and implement logical OR for shared level interrupts. The allocated irq_source_id can be freed by kvm_free_irq_source_id(). Currently, we support at most sizeof(unsigned long) different irq sources.

2008-10-28[S390] No more 4kb stacks.Heiko Carstens
We got a stack overflow with a small stack configuration on a 32 bit system. It just looks like as 4kb isn't enough and too dangerous. So lets get rid of 4kb stacks on 32 bit. But one thing I completely dislike about the call trace below is that just for debugging or tracing purposes sprintf gets called (cio_start_key): /* process condition code */ sprintf(dbf_txt, "ccode:%d", ccode); CIO_TRACE_EVENT(4, dbf_txt); But maybe its just me who thinks that this could be done better. <4>Kernel stack overflow. <4>Modules linked in: dm_multipath sunrpc bonding qeth_l2 dm_mod qeth ccwgroup vmur <4>CPU: 1 Not tainted 2.6.27-30.x.20081015-s390default #1 <4>Process httpd (pid: 3807, task: 20ae2df8, ksp: 1666fb78) <4>Krnl PSW : 040c0000 8027098a (number+0xe/0x348) <4> R:0 T:1 IO:0 EX:0 Key:0 M:1 W:0 P:0 AS:0 CC:0 PM:0 <4>Krnl GPRS: 00d43318 0027097c 1666f277 9666f270 <4> 00000000 00000000 0000000a ffffffff <4> 9666f270 1666f228 1666f277 1666f098 <4> 00000002 80270982 80271016 1666f098 <4>Krnl Code: 8027097e: f0340dd0a7f1 srp 3536(4,%r0),2033(%r10),4 <4> 80270984: 0f00 clcl %r0,%r0 <4> 80270986: a7840001 brc 8,80270988 <4> >8027098a: 18ef lr %r14,%r15 <4> 8027098c: a7faff68 ahi %r15,-152 <4> 80270990: 18bf lr %r11,%r15 <4> 80270992: 18a2 lr %r10,%r2 <4> 80270994: 1893 lr %r9,%r3 Modified calltrace with annotated stackframe size of each function: stackframe size | 0 304 vsnprintf+850 [0x271016] 1 72 sprintf+74 [0x271522] 2 56 cio_start_key+262 [0x2d4c16] 3 56 ccw_device_start_key+222 [0x2dfe92] 4 56 ccw_device_start+40 [0x2dff28] 5 48 raw3215_start_io+104 [0x30b0f8] 6 56 raw3215_write+494 [0x30ba0a] 7 40 con3215_write+68 [0x30bafc] 8 40 __call_console_drivers+146 [0x12b0fa] 9 32 _call_console_drivers+102 [0x12b192] 10 64 release_console_sem+268 [0x12b614] 11 168 vprintk+462 [0x12bca6] 12 72 printk+68 [0x12bfd0] 13 256 __print_symbol+50 [0x15a882] 14 56 __show_trace+162 [0x103d06] 15 32 show_trace+224 [0x103e70] 16 48 show_stack+152 [0x103f20] 17 56 dump_stack+126 [0x104612] 18 96 __alloc_pages_internal+592 [0x175004] 19 80 cache_alloc_refill+776 [0x196f3c] 20 40 __kmalloc+258 [0x1972ae] 21 40 __alloc_skb+94 [0x328086] 22 32 pskb_copy+50 [0x328252] 23 32 skb_realloc_headroom+110 [0x328a72] 24 104 qeth_l2_hard_start_xmit+378 [0x7803bfde] 25 56 dev_hard_start_xmit+450 [0x32ef6e] 26 56 __qdisc_run+390 [0x3425d6] 27 48 dev_queue_xmit+410 [0x331e06] 28 40 ip_finish_output+308 [0x354ac8] 29 56 ip_output+218 [0x355b6e] 30 24 ip_local_out+56 [0x354584] 31 120 ip_queue_xmit+300 [0x355cec] 32 96 tcp_transmit_skb+812 [0x367da8] 33 40 tcp_push_one+158 [0x369fda] 34 112 tcp_sendmsg+852 [0x35d5a0] 35 240 sock_sendmsg+164 [0x32035c] 36 56 kernel_sendmsg+86 [0x32064a] 37 88 sock_no_sendpage+98 [0x322b22] 38 104 tcp_sendpage+70 [0x35cc1e] 39 48 sock_sendpage+74 [0x31eb66] 40 64 pipe_to_sendpage+102 [0x1c4b2e] 41 64 __splice_from_pipe+120 [0x1c5340] 42 72 splice_from_pipe+90 [0x1c57e6] 43 56 generic_splice_sendpage+38 [0x1c5832] 44 48 do_splice_from+104 [0x1c4c38] 45 48 direct_splice_actor+52 [0x1c4c88] 46 80 splice_direct_to_actor+180 [0x1c4f80] 47 72 do_splice_direct+70 [0x1c5112] 48 64 do_sendfile+360 [0x19de18] 49 72 sys_sendfile64+126 [0x19df32] 50 336 sysc_do_restart+18 [0x111a1a] Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2008-10-28[S390] Fix sysdev class file creation.Heiko Carstens
Use sysdev_class_create_file() to create create sysdev class attributes instead of sysfs_create_file(). Using sysfs_create_file() wasn't a very good idea since the show and store functions have a different amount of parameters for sysfs files and sysdev class files. In particular the pointer to the buffer is the last argument and therefore accesses to random memory regions happened. Still worked surprisingly well until we got a kernel panic.

2008-10-28[S390] pgtables: Fix race in enable_sie vs. page table opsChristian Borntraeger
The current enable_sie code sets the mm->context.pgstes bit to tell dup_mm that the new mm should have extended page tables. This bit is also used by the s390 specific page table primitives to decide about the page table layout - which means context.pgstes has two meanings. This can cause any kind of bugs. For example - e.g. shrink_zone can call ptep_clear_flush_young while enable_sie is running. ptep_clear_flush_young will test for context.pgstes. Since enable_sie changed that value of the old struct mm without changing the page table layout ptep_clear_flush_young will do the wrong thing. The solution is to split pgstes into two bits - one for the allocation - one for the current state Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2008-10-27MIPS: TXx9: Make firmware parameter passing more robustGeert Uytterhoeven
When booting Linux on a txx9 board with VxWorks boot loader, it crashes in prom_getenv(), as VxWorks doesn't pass firmware parameters in a0-a3 (in my case, the actual leftover values in these registers were 0x80002000, 0x80001fe0, 0x2000, and 0x20). Make the parsing of argc, argv, and envp a bit more robust by checking if argc is a number below CKSEG0, and argv/envp point to CKSEG0.

Remove runtime db_* macros as we don't need them any more. In general, such helpers are useful for initial porting, but once approved, they are not indispensable. Signed-off-by: Shinya Kuribayashi <shinya.kuribayashi@necel.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
