| * hw-breakpoint: Keep track of dr7 local enable bitsFrederic Weisbecker2010-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the user enables breakpoints through dr7, he can choose between "local" or "global" enable bits but given how linux is implemented, both have the same effect. That said we don't keep track how the user enabled the breakpoints so when the user requests the dr7 value, we only translate the "enabled" status using the global enabled bits. It means that if the user enabled a breakpoint using the local enabled bit, reading back dr7 will set the global bit and clear the local one. Apps like Wine expect a full dr7 POKEUSER/PEEKUSER match for emulated softwares that implement old reverse engineering protection schemes. We fix that by keeping track of the whole dr7 value given by the user in the thread structure to drop this bug. We'll think about something more proper later. This fixes a 2.6.32 - 2.6.33-x ptrace regression.

| * hw-breakpoints: Accept breakpoints on NULL addressFrederic Weisbecker2010-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before we had a generic breakpoint API, ptrace was accepting breakpoints on NULL address in x86. The new API refuse them, without given strong reasons. We need to follow the previous behaviour as some userspace apps like Wine need such NULL breakpoints to ensure old emulated software protections are still working. This fixes a 2.6.32 - 2.6.33-x ptrace regression.

Those are of type 'int' but the structure is meant to have 'short'. So use uid16_t and gid16_t to correct this. Reported-by: Rob Landley <rob@landley.net> Signed-off-by: David S.

This can prevent systems booting properly. There is no clear hard-configurable default for this; the desired default depends on the nature of the userspace which is going to be booted. So, provide a way for the alignment fault handler to be configured via the kernel command line. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Previously, the "cpu-release-addr" property contained a value referencing the boot page translation address range of 0xfffffxxx, which then indirectly accessed RAM. The "cpu-release-addr" is currently ioremapped and the secondary cores kicked. However, due to the recent change in "cpu-release-addr", it sometimes points to a memory location in low memory that cannot be ioremapped. For example on a P2020-based board with 512MB of RAM the following error occurs on bootup: <...> mpic: requesting IPIs ... __ioremap(): phys addr 0x1ffff000 is RAM lr c05df9a0 Unable to handle kernel paging request for data at address 0x00000014 Faulting instruction address: 0xc05df9b0 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=2 P2020 RDB Modules linked in: <... eventual kernel panic> Adding logic to conditionally ioremap or access memory directly resolves the issue.

While this was implemented for 32-bit SH, sh64 neglected to make use of TIF_SINGLESTEP when it was folded in with the 32-bit code, resulting in ptrace_notify() never being called. As sh64 uses all of the other abstractions already, this simply plugs in the thread flag in the appropriate enable/disable paths and fixes up the tracehook notification accordingly. With this in place, sh64 is brought in line with what 32-bit is already doing. Reported-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Fix this by testing if we're single stepping or branch stepping and setting the flag accordingly. Tested, seems to work.

However, in the presence of CPU hotplug(with bios listing not enabled but possible cpus as disabled cpus in MADT), we have to consider the number of possible CPUs rather than the number of current CPUs; otherwise we may cross the 8-CPU boundary when CPUs are added later. 32bit apic code can use more cleanups (like the removal of vendor checks in 32bit default_setup_apic_routing()) and more unifications with 64bit code.
